=head1 NAME
|
|
|
|
find2perl - translate find command lines to Perl code
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
find2perl [paths] [predicates] | perl
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
find2perl is a little translator to convert find command lines to
|
|
equivalent Perl code. The resulting code is typically faster than
|
|
running find itself.
|
|
|
|
"paths" are a set of paths where find2perl will start its searches and
|
|
"predicates" are taken from the following list.
|
|
|
|
=over 4
|
|
|
|
=item C<! PREDICATE>
|
|
|
|
Negate the sense of the following predicate. The C<!> must be passed as
|
|
a distinct argument, so it may need to be surrounded by whitespace and/or
|
|
quoted from interpretation by the shell using a backslash (just as with
|
|
using C<find(1)>).
|
|
|
|
=item C<( PREDICATES )>
|
|
|
|
Group the given PREDICATES. The parentheses must be passed as distinct
|
|
arguments, so they may need to be surrounded by whitespace and/or
|
|
quoted from interpretation by the shell using a backslash (just as with
|
|
using C<find(1)>).
|
|
|
|
=item C<PREDICATE1 PREDICATE2>
|
|
|
|
True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not
|
|
evaluated if PREDICATE1 is false.
|
|
|
|
=item C<PREDICATE1 -o PREDICATE2>
|
|
|
|
True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is
|
|
not evaluated if PREDICATE1 is true.
|
|
|
|
=item C<-follow>
|
|
|
|
Follow (dereference) symlinks. The checking of file attributes depends
|
|
on the position of the C<-follow> option. If it precedes the file
|
|
check option, an C<stat> is done which means the file check applies to the
|
|
file the symbolic link is pointing to. If C<-follow> option follows the
|
|
file check option, this now applies to the symbolic link itself, i.e.
|
|
an C<lstat> is done.
|
|
|
|
=item C<-depth>
|
|
|
|
Change directory traversal algorithm from breadth-first to depth-first.
|
|
|
|
=item C<-prune>
|
|
|
|
Do not descend into the directory currently matched.
|
|
|
|
=item C<-xdev>
|
|
|
|
Do not traverse mount points (prunes search at mount-point directories).
|
|
|
|
=item C<-name GLOB>
|
|
|
|
File name matches specified GLOB wildcard pattern. GLOB may need to be
|
|
quoted to avoid interpretation by the shell (just as with using
|
|
C<find(1)>).
|
|
|
|
=item C<-perm PERM>
|
|
|
|
Low-order 9 bits of permission match octal value PERM.
|
|
|
|
=item C<-perm -PERM>
|
|
|
|
The bits specified in PERM are all set in file's permissions.
|
|
|
|
=item C<-type X>
|
|
|
|
The file's type matches perl's C<-X> operator.
|
|
|
|
=item C<-fstype TYPE>
|
|
|
|
Filesystem of current path is of type TYPE (only NFS/non-NFS distinction
|
|
is implemented).
|
|
|
|
=item C<-user USER>
|
|
|
|
True if USER is owner of file.
|
|
|
|
=item C<-group GROUP>
|
|
|
|
True if file's group is GROUP.
|
|
|
|
=item C<-nouser>
|
|
|
|
True if file's owner is not in password database.
|
|
|
|
=item C<-nogroup>
|
|
|
|
True if file's group is not in group database.
|
|
|
|
=item C<-inum INUM>
|
|
|
|
True file's inode number is INUM.
|
|
|
|
=item C<-links N>
|
|
|
|
True if (hard) link count of file matches N (see below).
|
|
|
|
=item C<-size N>
|
|
|
|
True if file's size matches N (see below) N is normally counted in
|
|
512-byte blocks, but a suffix of "c" specifies that size should be
|
|
counted in characters (bytes) and a suffix of "k" specifes that
|
|
size should be counted in 1024-byte blocks.
|
|
|
|
=item C<-atime N>
|
|
|
|
True if last-access time of file matches N (measured in days) (see
|
|
below).
|
|
|
|
=item C<-ctime N>
|
|
|
|
True if last-changed time of file's inode matches N (measured in days,
|
|
see below).
|
|
|
|
=item C<-mtime N>
|
|
|
|
True if last-modified time of file matches N (measured in days, see below).
|
|
|
|
=item C<-newer FILE>
|
|
|
|
True if last-modified time of file matches N.
|
|
|
|
=item C<-print>
|
|
|
|
Print out path of file (always true).
|
|
|
|
=item C<-print0>
|
|
|
|
Like -print, but terminates with \0 instead of \n.
|
|
|
|
=item C<-exec OPTIONS ;>
|
|
|
|
exec() the arguments in OPTIONS in a subprocess; any occurence of {} in
|
|
OPTIONS will first be substituted with the path of the current
|
|
file. Note that the command "rm" has been special-cased to use perl's
|
|
unlink() function instead (as an optimization). The C<;> must be passed as
|
|
a distinct argument, so it may need to be surrounded by whitespace and/or
|
|
quoted from interpretation by the shell using a backslash (just as with
|
|
using C<find(1)>).
|
|
|
|
=item C<-ok OPTIONS ;>
|
|
|
|
Like -exec, but first prompts user; if user's response does not begin
|
|
with a y, skip the exec. The C<;> must be passed as
|
|
a distinct argument, so it may need to be surrounded by whitespace and/or
|
|
quoted from interpretation by the shell using a backslash (just as with
|
|
using C<find(1)>).
|
|
|
|
=item C<-eval EXPR>
|
|
|
|
Has the perl script eval() the EXPR.
|
|
|
|
=item C<-ls>
|
|
|
|
Simulates C<-exec ls -dils {} ;>
|
|
|
|
=item C<-tar FILE>
|
|
|
|
Adds current output to tar-format FILE.
|
|
|
|
=item C<-cpio FILE>
|
|
|
|
Adds current output to old-style cpio-format FILE.
|
|
|
|
=item C<-ncpio FILE>
|
|
|
|
Adds current output to "new"-style cpio-format FILE.
|
|
|
|
=back
|
|
|
|
Predicates which take a numeric argument N can come in three forms:
|
|
|
|
* N is prefixed with a +: match values greater than N
|
|
* N is prefixed with a -: match values less than N
|
|
* N is not prefixed with either + or -: match only values equal to N
