718=head1 NAME
719
720find2perl - translate find command lines to Perl code
721
722=head1 SYNOPSIS
723
724 find2perl [paths] [predicates] | perl
725
726=head1 DESCRIPTION
727
728find2perl is a little translator to convert find command lines to
729equivalent Perl code. The resulting code is typically faster than
730running find itself.
731
732"paths" are a set of paths where find2perl will start its searches and
733"predicates" are taken from the following list.
734
735=over 4
736
737=item C<! PREDICATE>
738
739Negate the sense of the following predicate. The C<!> must be passed as
740a distinct argument, so it may need to be surrounded by whitespace and/or
741quoted from interpretation by the shell using a backslash (just as with
742using C<find(1)>).
743
744=item C<( PREDICATES )>
745
746Group the given PREDICATES. The parentheses must be passed as distinct
747arguments, so they may need to be surrounded by whitespace and/or
748quoted from interpretation by the shell using a backslash (just as with
749using C<find(1)>).
750
751=item C<PREDICATE1 PREDICATE2>
752
753True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not
754evaluated if PREDICATE1 is false.
755
756=item C<PREDICATE1 -o PREDICATE2>
757
758True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is
759not evaluated if PREDICATE1 is true.
760
761=item C<-follow>
762
3d1e7443 763Follow (dereference) symlinks. The checking of file attributes depends
764on the position of the C<-follow> option. If it precedes the file
765check option, an C<stat> is done which means the file check applies to the
766file the symbolic link is pointing to. If C<-follow> option follows the
767file check option, this now applies to the symbolic link itself, i.e.
768an C<lstat> is done.
431613dd 769
770=item C<-depth>
771
772Change directory traversal algorithm from breadth-first to depth-first.
773
774=item C<-prune>
775
776Do not descend into the directory currently matched.
777
778=item C<-xdev>
779
780Do not traverse mount points (prunes search at mount-point directories).
781
782=item C<-name GLOB>
783
784File name matches specified GLOB wildcard pattern. GLOB may need to be
785quoted to avoid interpretation by the shell (just as with using
786C<find(1)>).
787
6f028b01 788=item C<-iname GLOB>
789
790Like C<-name>, but the match is case insensitive.
791
792=item C<-path GLOB>
793
794Path name matches specified GLOB wildcard pattern.
795
796=item C<-ipath GLOB>
797
798Like C<-path>, but the match is case insensitive.
799
431613dd 800=item C<-perm PERM>
801
802Low-order 9 bits of permission match octal value PERM.
803
804=item C<-perm -PERM>
805
806The bits specified in PERM are all set in file's permissions.
807
808=item C<-type X>
809
810The file's type matches perl's C<-X> operator.
811
812=item C<-fstype TYPE>
813
814Filesystem of current path is of type TYPE (only NFS/non-NFS distinction
815is implemented).
816
817=item C<-user USER>
818
819True if USER is owner of file.
820
821=item C<-group GROUP>
822
823True if file's group is GROUP.
824
825=item C<-nouser>
826
827True if file's owner is not in password database.
828
829=item C<-nogroup>
830
831True if file's group is not in group database.
832
833=item C<-inum INUM>
834
835True file's inode number is INUM.
836
837=item C<-links N>
838
839True if (hard) link count of file matches N (see below).
840
841=item C<-size N>
842
843True if file's size matches N (see below) N is normally counted in
844512-byte blocks, but a suffix of "c" specifies that size should be
845counted in characters (bytes) and a suffix of "k" specifes that
846size should be counted in 1024-byte blocks.
847
848=item C<-atime N>
849
850True if last-access time of file matches N (measured in days) (see
851below).
852
853=item C<-ctime N>
854
855True if last-changed time of file's inode matches N (measured in days,
856see below).
857
858=item C<-mtime N>
859
860True if last-modified time of file matches N (measured in days, see below).
861
862=item C<-newer FILE>
863
864True if last-modified time of file matches N.
865
866=item C<-print>
867
9c4673c1 868Print out path of file (always true). If none of C<-exec>, C<-ls>,
869C<-print0>, or C<-ok> is specified, then C<-print> will be added
870implicitly.
431613dd 871
872=item C<-print0>
873
874Like -print, but terminates with \0 instead of \n.
875
876=item C<-exec OPTIONS ;>
877
fb8eeed8 878exec() the arguments in OPTIONS in a subprocess; any occurrence of {} in
431613dd 879OPTIONS will first be substituted with the path of the current
880file. Note that the command "rm" has been special-cased to use perl's
881unlink() function instead (as an optimization). The C<;> must be passed as
882a distinct argument, so it may need to be surrounded by whitespace and/or
883quoted from interpretation by the shell using a backslash (just as with
884using C<find(1)>).
885
886=item C<-ok OPTIONS ;>
887
888Like -exec, but first prompts user; if user's response does not begin
889with a y, skip the exec. The C<;> must be passed as
890a distinct argument, so it may need to be surrounded by whitespace and/or
891quoted from interpretation by the shell using a backslash (just as with
892using C<find(1)>).
893
928e06a6 894=item C<-eval EXPR>
431613dd 895
928e06a6 896Has the perl script eval() the EXPR.
431613dd 897
898=item C<-ls>
899
900Simulates C<-exec ls -dils {} ;>
901
902=item C<-tar FILE>
903
904Adds current output to tar-format FILE.
905
906=item C<-cpio FILE>
907
908Adds current output to old-style cpio-format FILE.
909
910=item C<-ncpio FILE>
911
912Adds current output to "new"-style cpio-format FILE.
913
914=back
915
916Predicates which take a numeric argument N can come in three forms:
917
918 * N is prefixed with a +: match values greater than N
919 * N is prefixed with a -: match values less than N
920 * N is not prefixed with either + or -: match only values equal to N
