|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
recursively descends the directory tree for each
|
||||
.Ar file
|
||||
listed, evaluating an
|
||||
.Ar expression
|
||||
(composed of the
|
||||
.Dq primaries
|
||||
and
|
||||
.Dq operands
|
||||
listed below) in terms
|
||||
of each file in the tree.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl H
|
||||
Causes the file information and file type (see
|
||||
.Xr stat 2 )
|
||||
returned for each symbolic link encountered on the command line to be
|
||||
those of the file referenced by the link, not the link itself.
|
||||
If the referenced file does not exist, the file information and type will
|
||||
be for the link itself.
|
||||
File information of all symbolic links not on the command line is that
|
||||
of the link itself.
|
||||
.It Fl L
|
||||
Causes the file information and file type (see
|
||||
.Xr stat 2 )
|
||||
returned for each symbolic link to be those of the file referenced by the
|
||||
link, not the link itself.
|
||||
If the referenced file does not exist, the file information and type will
|
||||
be for the link itself.
|
||||
.It Fl P
|
||||
Causes the file information and file type (see
|
||||
.Xr stat 2 )
|
||||
returned for each symbolic link to be those of the link itself.
|
||||
.It Fl d
|
||||
Causes
|
||||
.Nm
|
||||
to perform a depth-first traversal, i.e., directories
|
||||
are visited in post-order, and all entries in a directory will be acted
|
||||
on before the directory itself.
|
||||
By default,
|
||||
.Nm
|
||||
visits directories in pre-order, i.e., before their contents.
|
||||
Note, the default is
|
||||
.Ar not
|
||||
a breadth-first traversal.
|
||||
.It Fl E
|
||||
Causes
|
||||
.Ar regexp
|
||||
arguments to primaries to be interpreted as extended regular
|
||||
expressions (see
|
||||
.Xr re_format 7 ) .
|
||||
.It Fl f
|
||||
Specifies a file hierarchy for
|
||||
.Nm
|
||||
to traverse.
|
||||
File hierarchies may also be specified as the operands immediately
|
||||
following the options.
|
||||
.It Fl h
|
||||
Causes the file information and file type (see
|
||||
.Xr stat 2 )
|
||||
returned for each symbolic link to be those of the file referenced by the
|
||||
link, not the link itself.
|
||||
If the referenced file does not exist, the file information and type will
|
||||
be for the link itself.
|
||||
.It Fl s
|
||||
Causes the entries of each directory to be sorted in
|
||||
lexicographical order.
|
||||
Note that the sorting is done only inside of each directory;
|
||||
files in different directories are not sorted.
|
||||
Therefore,
|
||||
.Sq Li a/b
|
||||
appears before
|
||||
.Sq Li a.b ,
|
||||
which is different from
|
||||
.Dq Li "find ... \&| sort"
|
||||
order.
|
||||
.It Fl X
|
||||
Modifies the output to permit
|
||||
.Nm
|
||||
to be safely used in conjunction with
|
||||
.Xr xargs 1 .
|
||||
If a file name contains any of the delimiting characters used by
|
||||
.Xr xargs 1 ,
|
||||
a diagnostic message is displayed on standard error, and the file
|
||||
is skipped.
|
||||
The delimiting characters include single
|
||||
.Pq Dq \&'
|
||||
and double
|
||||
.Pq Dq \&"
|
||||
quotes, backslash
|
||||
.Pq Dq \e ,
|
||||
space, tab, and newline characters.
|
||||
Alternatively, the
|
||||
.Ic -print0
|
||||
or
|
||||
.Ic -printx
|
||||
primaries can be used to format the output in a way that
|
||||
.Xr xargs 1
|
||||
can accept.
|
||||
.It Fl x
|
||||
Restricts the search to the file system containing the
|
||||
directory specified.
|
||||
Does not list mount points to other file systems.
|
||||
.El
|
||||
.Sh PRIMARIES
|
||||
All primaries which take a numeric argument of
|
||||
.Ar n
|
||||
allow the number to be preceded by a plus sign
|
||||
.Pq Dq \&+
|
||||
or a minus sign
|
||||
.Pq Dq \- .
|
||||
A preceding plus sign means
|
||||
.Dq more than Ar n ,
|
||||
a preceding minus sign means
|
||||
.Dq less than Ar n ,
|
||||
and neither means
|
||||
.Dq exactly Ar n .
|
||||
.Pp
|
||||
.Bl -tag -width Ds -compact
|
||||
.It Ic -amin Ar n
|
||||
True if the difference between the file last access time and the time
|
||||
.Nm
|
||||
was started, rounded up to the next full minute, is
|
||||
.Ar n
|
||||
minutes.
|
||||
.Pp
|
||||
.It Ic -anewer Ar file
|
||||
True if the current file has a more recent last access time than
|
||||
.Ar file .
|
||||
.Pp
|
||||
.It Ic -atime Ar n
|
||||
True if the difference between the file last access time and the time
|
||||
.Nm
|
||||
was started, rounded up to the next full 24-hour period, is
|
||||
.Ar n
|
||||
24-hour periods.
|
||||
.Pp
|
||||
.It Ic -cmin Ar n
|
||||
True if the difference between the time of last change of file status
|
||||
information and the time
|
||||
.Nm
|
||||
was started, rounded up to the next full minute, is
|
||||
.Ar n
|
||||
minutes.
|
||||
.Pp
|
||||
.It Ic -cnewer Ar file
|
||||
True if the current file has a more recent last change time than
|
||||
.Ar file .
|
||||
.Pp
|
||||
.It Ic -ctime Ar n
|
||||
True if the difference between the time of last change of file status
|
||||
information and the time
|
||||
.Nm
|
||||
was started, rounded up to the next full 24-hour period, is
|
||||
.Ar n
|
||||
24-hour periods.
|
||||
.Pp
|
||||
.It Ic -delete
|
||||
Delete found files, symbolic links, and directories.
|
||||
Always returns true.
|
||||
This executes from the current working directory as
|
||||
.Nm
|
||||
recurses down the tree.
|
||||
To avoid deleting unexpected files, it will ignore any filenames that
|
||||
.Xr fts 3
|
||||
returns that contain a
|
||||
.Dq /
|
||||
.Xr ( fts 3
|
||||
should not return such pathnames).
|
||||
Depth-first traversal processing is implied by this option.
|
||||
This primary can also be invoked as
|
||||
.Ic -rm .
|
||||
.Pp
|
||||
.It Ic -empty
|
||||
True if the current file or directory is empty.
|
||||
.Pp
|
||||
.It Ic -exec Ar utility Oo argument ... Oc Ic \&;
|
||||
.It Ic -exec Ar utility Oo argument ... Oc Ic {} Ic \&+
|
||||
Execute the specified
|
||||
.Ar utility
|
||||
with the specified arguments.
|
||||
.Pp
|
||||
The list of arguments for
|
||||
.Ar utility
|
||||
is terminated by a lone semicolon
|
||||
.Dq Ic \&;
|
||||
or plus
|
||||
.Dq Ic \&+
|
||||
character as a separate parameter.
|
||||
The command specified by
|
||||
.Ar utility
|
||||
will be executed with its current working directory being the directory
|
||||
from which
|
||||
.Nm
|
||||
was executed.
|
||||
.Pp
|
||||
If the list of arguments is terminated by a semicolon
|
||||
.Pq Dq Ic \&; ,
|
||||
then
|
||||
.Ar utility
|
||||
is invoked once per pathname.
|
||||
If
|
||||
the string
|
||||
.Dq Ic {}
|
||||
appears one or more times in the utility name or arguments,
|
||||
then it is replaced by the pathname of the current file
|
||||
(but it need not appear, in which case the pathname
|
||||
will not be passed to
|
||||
.Ar utility ) .
|
||||
The semicolon-terminated form of the
|
||||
.Ic -exec
|
||||
primary returns true if and only if
|
||||
.Ar utility
|
||||
exits with a zero exit status.
|
||||
Note that the semicolon will have to be escaped on the shell command line
|
||||
in order to be passed as a parameter.
|
||||
.Pp
|
||||
If the list of arguments is terminated by a plus sign
|
||||
.Pq Dq Ic \&+ ,
|
||||
then the pathnames for which the primary is evaluated are aggregated
|
||||
into sets, and
|
||||
.Ar utility
|
||||
will be invoked once per set, similar to
|
||||
.Xr xargs 1 .
|
||||
In this case the string
|
||||
.Dq Ic {}
|
||||
must appear, and must appear as the last item in the argument list,
|
||||
just before the
|
||||
.Dq Ic \&+
|
||||
parameter, and is replaced by the pathnames of the current set of files.
|
||||
Each set is limited to no more than 5,000 pathnames,
|
||||
and is also limited such that the total number of bytes in the argument
|
||||
list does not exceed
|
||||
.Dv ARG_MAX .
|
||||
The plus-terminated form of the
|
||||
.Ic -exec
|
||||
primary always returns true.
|
||||
If the plus-terminated form of the
|
||||
.Ic -exec
|
||||
primary results in any invocation of
|
||||
.Ar utility
|
||||
exiting with non-zero exit status, then
|
||||
.Nm
|
||||
will eventually exit with non-zero status as well,
|
||||
but this does not cause
|
||||
.Nm
|
||||
to exit early.
|
||||
.Pp
|
||||
.It Ic -execdir Ar utility Oo argument ... Oc Ic \&;
|
||||
The
|
||||
.Ic -execdir
|
||||
primary is similar to the semicolon-terminated
|
||||
.Pq Dq Ic \&;
|
||||
variant of the
|
||||
.Ic -exec
|
||||
primary, with the exception that
|
||||
.Ar utility
|
||||
will be executed from the directory that holds
|
||||
the current file.
|
||||
Only the base filename is substituted for the string
|
||||
.Dq Ic {} .
|
||||
Set aggregation
|
||||
.Pq Do Ic \&+ Dc termination
|
||||
is not supported.
|
||||
.Pp
|
||||
.It Ic -exit Op Ar status
|
||||
This primary causes
|
||||
.Nm
|
||||
to stop traversing the file system and exit immediately,
|
||||
with the specified numeric exit status.
|
||||
If the
|
||||
.Ar status
|
||||
value is not specified, then
|
||||
.Nm
|
||||
will exit with status zero.
|
||||
Note that any preceding primaries will be evaluated and acted upon
|
||||
before exiting.
|
||||
.Pp
|
||||
.It Ic -false
|
||||
This primary always evaluates to false.
|
||||
This can be used following a primary that caused the
|
||||
expression to be true to make the expression to be false.
|
||||
This can be useful after using a
|
||||
.Ic -fprint
|
||||
primary so it can continue to the next expression (using an
|
||||
.Cm -or
|
||||
operator, for example).
|
||||
.Pp
|
||||
.It Ic -flags Oo Fl Oc Ns Ar flags
|
||||
If
|
||||
.Ar flags
|
||||
are preceded by a dash
|
||||
.Pq Dq Ic \- ,
|
||||
this primary evaluates to true
|
||||
if at least all of the bits in
|
||||
.Ar flags
|
||||
are set in the file's flags bits.
|
||||
If
|
||||
.Ar flags
|
||||
are not preceded by a dash, this primary evaluates to true if
|
||||
the bits in
|
||||
.Ar flags
|
||||
exactly match the file's flags bits.
|
||||
If

Follow symbolic links.
|
||||
.Pp
|
||||
.It Ic -fprint Ar filename
|
||||
This primary always evaluates to true.
|
||||
This creates
|
||||
.Ar filename
|
||||
or overwrites the file if it already exists.
|
||||
The file is created at startup.
|
||||
It writes the pathname of the current file to this file, followed
|
||||
by a newline character.
|
||||
The file will be empty if no files are matched.
|

.Pp
|
||||
.It Ic -fstype Ar type
|
||||
True if the file is contained in a file system of type
|
||||
.Ar type .
|
||||
The
|
||||
.Xr sysctl 8
|
||||
command can be used to find out the types of file systems
|
||||
that are available on the system:
|
||||
.Bd -literal -offset indent
|
||||
sysctl vfs.generic.fstypes
|
||||
.Ed
|
||||
.Pp
|
||||
In addition, there are two pseudo-types,
|
||||
.Dq local
|
||||
and
|
||||
.Dq rdonly .
|
||||
The former matches any file system physically mounted on the system where
|
||||
the
|
||||
.Nm
|
||||
is being executed, and the latter matches any file system which is
|
||||
mounted read-only.
|
||||
.Pp
|
||||
.It Ic -group Ar gname
|
||||
True if the file belongs to the group
|
||||
.Ar gname .
|
||||
If
|
||||
.Ar gname
|
||||
is numeric and there is no such group name, then
|
||||
.Ar gname
|
||||
is treated as a group id.
|
||||
.Pp
|
||||
.It Ic -iname Ar pattern
|
||||
True if the last component of the pathname being examined matches
|
||||
.Ar pattern
|

.Pp
|
||||
.It Ic -iregex Ar regexp
|
||||
True if the path name of the current file matches the case-insensitive
|
||||
basic regular expression
|
||||
.Pq see Xr re_format 7
|
||||
.Ar regexp .
|
||||
This is a match on the whole path, not a search for the regular expression
|
||||
within the path.
|
||||
.Pp
|
||||
.It Ic -links Ar n
|
||||
True if the file has
|

.Pp
|
||||
.It Ic -rm
|
||||
This primary is an alias for
|
||||
.Ic -delete .
|
||||
.Pp
|
||||
.It Ic -ls
|
||||
This primary always evaluates to true.
|
||||
The following information for the current file is written to standard output:
|
||||
its inode number, size in 512-byte blocks, file permissions, number of hard
|
||||
links, owner, group, size in bytes, last modification time, and pathname.
|
||||
If the file is a block or character special file, the major and minor numbers
|
||||
will be displayed instead of the size in bytes.
|
||||
If the file is a symbolic link, the pathname of the linked-to file will be
|
||||
displayed preceded by
|
||||
.Dq -\*[Gt] .
|
||||
The format is identical to that produced by
|
||||
.Dq ls -dgils .
|
||||
.Pp
|
||||
.It Ic -maxdepth Ar n
|

.It Ic -mindepth Ar n
|
||||
True if the current search depth is at least what is specified in
|
||||
.Ar n .
|
||||
.Pp
|
||||
.It Ic -mmin Ar n
|
||||
True if the difference between the file last modification time and the time

.It Ic -ok Ar utility Oo argument ... Oc Ic \&;
|
||||
The

.Ic -ok
|
||||
primary is similar to the semicolon-terminated
|
||||
.Pq Dq \&;
|
||||
variant of the
|

.Ic -exec
|
||||
primary, with the exception that
|

.Nm
|

requests user affirmation for the execution of
|

.Ar utility
|

by printing
|

a message to the terminal and reading a response.
|

.Pp
|

.It Ic -perm Oo Fl Oc Ns Ar mode
|
||||
The
|
||||
.Ar mode
|
||||
may be either symbolic (see
|
||||
.Xr chmod 1 )
|
||||
or an octal number.
|
||||
If the mode is symbolic, a starting value of zero is assumed and the
|

mode sets or clears permissions without regard to the process' file mode
|

of the file's mode bits participate
|

in the comparison.
|

If the mode is preceded by a dash
|
||||
.Pq Dq Ic \- ,
|
||||
this primary evaluates to true
|
||||
if at least all of the bits in the mode are set in the file's mode bits.
|
||||
If the mode is not preceded by a dash, this primary evaluates to true if
|
||||
the bits in the mode exactly match the file's mode bits.
|
||||
Note, the first character of a symbolic mode may not be a dash
|
||||
.Pq Dq Ic \- .
|

.Pp
|

It prints the pathname of the current file to standard output,
|
||||
with each space, tab, newline, backslash, dollar sign, and single,
|
||||
double, or back quotation mark prefixed by a backslash, so the output of
|

True if the file belongs to the user
|

.Ar uname .
|
||||
If
|
||||
.Ar uname
|
||||
is numeric and there is no such user name, then
|
||||
.Ar uname
|
||||
is treated as a user id (and considered a numeric argument).
|
||||
.Pp
|
||||
.It Ic -xdev
|

This primary always evaluates to true.
|

.Sh OPERATORS
|
||||
The primaries may be combined using the following operators.
|
||||
The operators are listed in order of decreasing precedence.
|
||||
.Bl -tag -width (expression)
|
||||
.It Cm \&( Ar expression Cm \&)
|
||||
This evaluates to true if the parenthesized expression evaluates to
|
||||
true.
|
||||
.It Cm \&! Ar expression
|
||||
This is the unary
|
||||
.Tn NOT
|
||||
operator.
|
||||
It evaluates to true if the expression is false.
|
||||
.It Ar expression Cm -and Ar expression
|
||||
.It Ar expression expression
|
||||
The
|
||||
.Cm -and
|
||||
operator is the logical
|
||||
.Tn AND
|
||||
operator.
|
||||
As it is implied by the juxtaposition of two expressions it does not
|
||||
have to be specified.
|
||||
The expression evaluates to true if both expressions are true.
|
||||
The second expression is not evaluated if the first expression is false.
|
||||
.It Ar expression Cm -or Ar expression
|
||||
The
|
||||
.Cm -or
|
||||
operator is the logical
|
||||
.Tn OR
|
||||
operator.
|
||||
The expression evaluates to true if either the first or the second expression
|
||||
is true.
|
||||
The second expression is not evaluated if the first expression is true.
|
||||
.El
|
||||
.Pp
|
||||
All operands and primaries must be separate arguments to
|
||||
.Nm .
|
||||
Primaries which themselves take arguments expect each argument
|
||||
to be a separate argument to
|
||||
.Nm .
|
||||
.Sh EXIT STATUS
|
||||
The
|
||||
.Nm
|
||||
utility normally exits 0 on success, and exits with 1 under certain
|
||||
internal error conditions.
|
||||
If any invocations of
|
||||
.Dq Ic -exec Ar ... Ic \&+
|
||||
primaries return non-zero exit-status, then
|
||||
.Nm
|
||||
will do so as well.
|
||||
.Sh EXAMPLES
|
||||
The following examples are shown as given to the shell:
|
||||

|

|
||||
primaries are extensions to
|
||||
.St -p1003.2 .
|

.Pp
|
||||
Historically, the
|
||||
.Fl d ,
|
||||
.Fl h ,
|
||||
and
|
||||
.Fl x
|
||||
options were implemented using the primaries
|
||||
.Dq Ic -depth ,
|
||||
.Dq Ic -follow ,
|
||||
and
|
||||
.Dq Ic -xdev .
|
||||
These primaries always evaluated to true, and always
|
||||
took effect when the
|
||||
.Ar expression
|
||||
was parsed, before the file system traversal began.
|
||||
As a result, some legal expressions could be confusing.
|
||||
For example, in the expression
|
||||
.Dq Ic -print Ic -or Ic -depth ,
|
||||
.Ic -print
|
||||
always evaluates to true, so the standard meaning of
|
||||
.Ic -or
|
||||
implies that
|
||||
.Ic -depth
|
||||
would never be evaluated, but that is not what happens;
|
||||
in fact,
|
||||
.Ic -depth
|
||||
takes effect immediately, without testing whether
|
||||
.Ic -print
|
||||
returns true or false.
|
||||
.Pp
|
||||
Historically, the operator
|
||||
.Dq Ic -or
|
||||
was implemented as
|
||||
.Dq Ic -o ,
|
||||
and the operator
|
||||
.Dq Ic -and
|
||||
was implemented as
|
||||
.Dq Ic -a .
|
||||
.Pp
|
||||
Historic implementations of the
|
||||
.Dq Ic -exec
|
||||
and
|
||||
.Dq Ic -ok
|
||||
primaries did not replace the string
|
||||
.Dq Ic {}
|
||||
in the utility name or the
|
||||
utility arguments if it did not appear as a separate argument.
|
||||
This version replaces it no matter where in the utility name or arguments
|
||||
it appears.
|
||||
.Pp
|
||||
Support for
|
||||
.Dq Ic -exec Ar ... Ic \&+
|
||||
is consistent with
|
||||
.Em IEEE PASC Interpretation 1003.2 #210 ,
|
||||
though the feature originated in

.Tn SVR4 .
|
||||
.Pp
|
||||
The
|
||||
.Ic -delete
|
||||
primary does not interact well with other options that cause the file system
|
||||
tree traversal options to be changed.
|
||||
.Sh HISTORY
|
||||
A much simpler
|
||||
.Nm
|
||||
command appeared in First Edition AT\*[Am]T Unix.
|
||||
The syntax had become similar to the present version by
|
||||
the time of the Fifth Edition.
|
||||
.Sh BUGS
|
||||
The special characters used by
|
||||
.Nm
|
||||
are also special characters to many shell programs.
|
||||
In particular, the characters
|
||||
.Dq \&* ,
|
||||
.Dq \&[ ,
|
||||
.Dq \&] ,
|
||||
.Dq \&? ,
|
||||
.Dq \&( ,
|
||||
.Dq \&) ,
|
||||
.Dq \&! ,
|
||||
.Dq \e ,
|
||||
and
|
||||
.Dq \&;
|
||||
may have to be escaped from the shell.
|
||||
.Pp
|
||||
As there is no delimiter separating options and file names or file
|
||||
names and the
|
||||
.Ar expression ,
|
||||
it is difficult to specify files named
|
||||
.Dq -xdev
|
||||
or
|
||||
.Dq \&! .
|
||||
These problems are handled by the
|
||||
.Fl f
|
||||
option and the
|
||||
.Xr getopt 3
|
||||
.Dq --
|
||||
construct.
