683 | =head1 NAME | |
684 | ||
685 | find2perl - translate find command lines to Perl code | |
686 | ||
687 | =head1 SYNOPSIS | |
688 | ||
689 | find2perl [paths] [predicates] | perl | |
690 | ||
691 | =head1 DESCRIPTION | |
692 | ||
693 | find2perl is a little translator to convert find command lines to | |
694 | equivalent Perl code. The resulting code is typically faster than | |
695 | running find itself. | |
696 | ||
697 | "paths" are a set of paths where find2perl will start its searches and | |
698 | "predicates" are taken from the following list. | |
699 | ||
700 | =over 4 | |
701 | ||
702 | =item C<! PREDICATE> | |
703 | ||
704 | Negate the sense of the following predicate. The C<!> must be passed as | |
705 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
706 | quoted from interpretation by the shell using a backslash (just as with | |
707 | using C<find(1)>). | |
708 | ||
709 | =item C<( PREDICATES )> | |
710 | ||
711 | Group the given PREDICATES. The parentheses must be passed as distinct | |
712 | arguments, so they may need to be surrounded by whitespace and/or | |
713 | quoted from interpretation by the shell using a backslash (just as with | |
714 | using C<find(1)>). | |
715 | ||
716 | =item C<PREDICATE1 PREDICATE2> | |
717 | ||
718 | True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not | |
719 | evaluated if PREDICATE1 is false. | |
720 | ||
721 | =item C<PREDICATE1 -o PREDICATE2> | |
722 | ||
723 | True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is | |
724 | not evaluated if PREDICATE1 is true. | |
725 | ||
726 | =item C<-follow> | |
727 | ||
3d1e7443 GS |
728 | Follow (dereference) symlinks. The checking of file attributes depends |
729 | on the position of the C<-follow> option. If it precedes the file | |
730 | check option, an C<stat> is done which means the file check applies to the | |
731 | file the symbolic link is pointing to. If C<-follow> option follows the | |
732 | file check option, this now applies to the symbolic link itself, i.e. | |
733 | an C<lstat> is done. | |
431613dd GS |
734 | |
735 | =item C<-depth> | |
736 | ||
737 | Change directory traversal algorithm from breadth-first to depth-first. | |
738 | ||
739 | =item C<-prune> | |
740 | ||
741 | Do not descend into the directory currently matched. | |
742 | ||
743 | =item C<-xdev> | |
744 | ||
745 | Do not traverse mount points (prunes search at mount-point directories). | |
746 | ||
747 | =item C<-name GLOB> | |
748 | ||
749 | File name matches specified GLOB wildcard pattern. GLOB may need to be | |
750 | quoted to avoid interpretation by the shell (just as with using | |
751 | C<find(1)>). | |
752 | ||
753 | =item C<-perm PERM> | |
754 | ||
755 | Low-order 9 bits of permission match octal value PERM. | |
756 | ||
757 | =item C<-perm -PERM> | |
758 | ||
759 | The bits specified in PERM are all set in file's permissions. | |
760 | ||
761 | =item C<-type X> | |
762 | ||
763 | The file's type matches perl's C<-X> operator. | |
764 | ||
765 | =item C<-fstype TYPE> | |
766 | ||
767 | Filesystem of current path is of type TYPE (only NFS/non-NFS distinction | |
768 | is implemented). | |
769 | ||
770 | =item C<-user USER> | |
771 | ||
772 | True if USER is owner of file. | |
773 | ||
774 | =item C<-group GROUP> | |
775 | ||
776 | True if file's group is GROUP. | |
777 | ||
778 | =item C<-nouser> | |
779 | ||
780 | True if file's owner is not in password database. | |
781 | ||
782 | =item C<-nogroup> | |
783 | ||
784 | True if file's group is not in group database. | |
785 | ||
786 | =item C<-inum INUM> | |
787 | ||
788 | True file's inode number is INUM. | |
789 | ||
790 | =item C<-links N> | |
791 | ||
792 | True if (hard) link count of file matches N (see below). | |
793 | ||
794 | =item C<-size N> | |
795 | ||
796 | True if file's size matches N (see below) N is normally counted in | |
797 | 512-byte blocks, but a suffix of "c" specifies that size should be | |
798 | counted in characters (bytes) and a suffix of "k" specifes that | |
799 | size should be counted in 1024-byte blocks. | |
800 | ||
801 | =item C<-atime N> | |
802 | ||
803 | True if last-access time of file matches N (measured in days) (see | |
804 | below). | |
805 | ||
806 | =item C<-ctime N> | |
807 | ||
808 | True if last-changed time of file's inode matches N (measured in days, | |
809 | see below). | |
810 | ||
811 | =item C<-mtime N> | |
812 | ||
813 | True if last-modified time of file matches N (measured in days, see below). | |
814 | ||
815 | =item C<-newer FILE> | |
816 | ||
817 | True if last-modified time of file matches N. | |
818 | ||
819 | =item C<-print> | |
820 | ||
821 | Print out path of file (always true). | |
822 | ||
823 | =item C<-print0> | |
824 | ||
825 | Like -print, but terminates with \0 instead of \n. | |
826 | ||
827 | =item C<-exec OPTIONS ;> | |
828 | ||
829 | exec() the arguments in OPTIONS in a subprocess; any occurence of {} in | |
830 | OPTIONS will first be substituted with the path of the current | |
831 | file. Note that the command "rm" has been special-cased to use perl's | |
832 | unlink() function instead (as an optimization). The C<;> must be passed as | |
833 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
834 | quoted from interpretation by the shell using a backslash (just as with | |
835 | using C<find(1)>). | |
836 | ||
837 | =item C<-ok OPTIONS ;> | |
838 | ||
839 | Like -exec, but first prompts user; if user's response does not begin | |
840 | with a y, skip the exec. The C<;> must be passed as | |
841 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
842 | quoted from interpretation by the shell using a backslash (just as with | |
843 | using C<find(1)>). | |
844 | ||
928e06a6 | 845 | =item C<-eval EXPR> |
431613dd | 846 | |
928e06a6 | 847 | Has the perl script eval() the EXPR. |
431613dd GS |
848 | |
849 | =item C<-ls> | |
850 | ||
851 | Simulates C<-exec ls -dils {} ;> | |
852 | ||
853 | =item C<-tar FILE> | |
854 | ||
855 | Adds current output to tar-format FILE. | |
856 | ||
857 | =item C<-cpio FILE> | |
858 | ||
859 | Adds current output to old-style cpio-format FILE. | |
860 | ||
861 | =item C<-ncpio FILE> | |
862 | ||
863 | Adds current output to "new"-style cpio-format FILE. | |
864 | ||
865 | =back | |
866 | ||
867 | Predicates which take a numeric argument N can come in three forms: | |
868 | ||
869 | * N is prefixed with a +: match values greater than N | |
870 | * N is prefixed with a -: match values less than N | |
871 | * N is not prefixed with either + or -: match only values equal to N | |
