667 | =head1 NAME | |
668 | ||
669 | find2perl - translate find command lines to Perl code | |
670 | ||
671 | =head1 SYNOPSIS | |
672 | ||
673 | find2perl [paths] [predicates] | perl | |
674 | ||
675 | =head1 DESCRIPTION | |
676 | ||
677 | find2perl is a little translator to convert find command lines to | |
678 | equivalent Perl code. The resulting code is typically faster than | |
679 | running find itself. | |
680 | ||
681 | "paths" are a set of paths where find2perl will start its searches and | |
682 | "predicates" are taken from the following list. | |
683 | ||
684 | =over 4 | |
685 | ||
686 | =item C<! PREDICATE> | |
687 | ||
688 | Negate the sense of the following predicate. The C<!> must be passed as | |
689 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
690 | quoted from interpretation by the shell using a backslash (just as with | |
691 | using C<find(1)>). | |
692 | ||
693 | =item C<( PREDICATES )> | |
694 | ||
695 | Group the given PREDICATES. The parentheses must be passed as distinct | |
696 | arguments, so they may need to be surrounded by whitespace and/or | |
697 | quoted from interpretation by the shell using a backslash (just as with | |
698 | using C<find(1)>). | |
699 | ||
700 | =item C<PREDICATE1 PREDICATE2> | |
701 | ||
702 | True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not | |
703 | evaluated if PREDICATE1 is false. | |
704 | ||
705 | =item C<PREDICATE1 -o PREDICATE2> | |
706 | ||
707 | True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is | |
708 | not evaluated if PREDICATE1 is true. | |
709 | ||
710 | =item C<-follow> | |
711 | ||
712 | Follow (dereference) symlinks. [XXX doesn't work fully, see L<BUGS>] | |
713 | ||
714 | =item C<-depth> | |
715 | ||
716 | Change directory traversal algorithm from breadth-first to depth-first. | |
717 | ||
718 | =item C<-prune> | |
719 | ||
720 | Do not descend into the directory currently matched. | |
721 | ||
722 | =item C<-xdev> | |
723 | ||
724 | Do not traverse mount points (prunes search at mount-point directories). | |
725 | ||
726 | =item C<-name GLOB> | |
727 | ||
728 | File name matches specified GLOB wildcard pattern. GLOB may need to be | |
729 | quoted to avoid interpretation by the shell (just as with using | |
730 | C<find(1)>). | |
731 | ||
732 | =item C<-perm PERM> | |
733 | ||
734 | Low-order 9 bits of permission match octal value PERM. | |
735 | ||
736 | =item C<-perm -PERM> | |
737 | ||
738 | The bits specified in PERM are all set in file's permissions. | |
739 | ||
740 | =item C<-type X> | |
741 | ||
742 | The file's type matches perl's C<-X> operator. | |
743 | ||
744 | =item C<-fstype TYPE> | |
745 | ||
746 | Filesystem of current path is of type TYPE (only NFS/non-NFS distinction | |
747 | is implemented). | |
748 | ||
749 | =item C<-user USER> | |
750 | ||
751 | True if USER is owner of file. | |
752 | ||
753 | =item C<-group GROUP> | |
754 | ||
755 | True if file's group is GROUP. | |
756 | ||
757 | =item C<-nouser> | |
758 | ||
759 | True if file's owner is not in password database. | |
760 | ||
761 | =item C<-nogroup> | |
762 | ||
763 | True if file's group is not in group database. | |
764 | ||
765 | =item C<-inum INUM> | |
766 | ||
767 | True file's inode number is INUM. | |
768 | ||
769 | =item C<-links N> | |
770 | ||
771 | True if (hard) link count of file matches N (see below). | |
772 | ||
773 | =item C<-size N> | |
774 | ||
775 | True if file's size matches N (see below) N is normally counted in | |
776 | 512-byte blocks, but a suffix of "c" specifies that size should be | |
777 | counted in characters (bytes) and a suffix of "k" specifes that | |
778 | size should be counted in 1024-byte blocks. | |
779 | ||
780 | =item C<-atime N> | |
781 | ||
782 | True if last-access time of file matches N (measured in days) (see | |
783 | below). | |
784 | ||
785 | =item C<-ctime N> | |
786 | ||
787 | True if last-changed time of file's inode matches N (measured in days, | |
788 | see below). | |
789 | ||
790 | =item C<-mtime N> | |
791 | ||
792 | True if last-modified time of file matches N (measured in days, see below). | |
793 | ||
794 | =item C<-newer FILE> | |
795 | ||
796 | True if last-modified time of file matches N. | |
797 | ||
798 | =item C<-print> | |
799 | ||
800 | Print out path of file (always true). | |
801 | ||
802 | =item C<-print0> | |
803 | ||
804 | Like -print, but terminates with \0 instead of \n. | |
805 | ||
806 | =item C<-exec OPTIONS ;> | |
807 | ||
808 | exec() the arguments in OPTIONS in a subprocess; any occurence of {} in | |
809 | OPTIONS will first be substituted with the path of the current | |
810 | file. Note that the command "rm" has been special-cased to use perl's | |
811 | unlink() function instead (as an optimization). The C<;> must be passed as | |
812 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
813 | quoted from interpretation by the shell using a backslash (just as with | |
814 | using C<find(1)>). | |
815 | ||
816 | =item C<-ok OPTIONS ;> | |
817 | ||
818 | Like -exec, but first prompts user; if user's response does not begin | |
819 | with a y, skip the exec. The C<;> must be passed as | |
820 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
821 | quoted from interpretation by the shell using a backslash (just as with | |
822 | using C<find(1)>). | |
823 | ||
824 | =item C<-eval EXPR ;> | |
825 | ||
826 | Has the perl script eval() the EXPR. The C<;> must be passed as | |
827 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
828 | quoted from interpretation by the shell using a backslash (just as with | |
829 | using C<find(1)>). | |
830 | ||
831 | =item C<-ls> | |
832 | ||
833 | Simulates C<-exec ls -dils {} ;> | |
834 | ||
835 | =item C<-tar FILE> | |
836 | ||
837 | Adds current output to tar-format FILE. | |
838 | ||
839 | =item C<-cpio FILE> | |
840 | ||
841 | Adds current output to old-style cpio-format FILE. | |
842 | ||
843 | =item C<-ncpio FILE> | |
844 | ||
845 | Adds current output to "new"-style cpio-format FILE. | |
846 | ||
847 | =back | |
848 | ||
849 | Predicates which take a numeric argument N can come in three forms: | |
850 | ||
851 | * N is prefixed with a +: match values greater than N | |
852 | * N is prefixed with a -: match values less than N | |
853 | * N is not prefixed with either + or -: match only values equal to N | |
854 | ||
855 | =head1 BUGS | |
856 | ||
857 | The -follow option doesn't really work yet, because File::Find doesn't | |
858 | support following symlinks. | |
