716 | =head1 NAME | |
717 | ||
718 | find2perl - translate find command lines to Perl code | |
719 | ||
720 | =head1 SYNOPSIS | |
721 | ||
722 | find2perl [paths] [predicates] | perl | |
723 | ||
724 | =head1 DESCRIPTION | |
725 | ||
726 | find2perl is a little translator to convert find command lines to | |
727 | equivalent Perl code. The resulting code is typically faster than | |
728 | running find itself. | |
729 | ||
730 | "paths" are a set of paths where find2perl will start its searches and | |
731 | "predicates" are taken from the following list. | |
732 | ||
733 | =over 4 | |
734 | ||
735 | =item C<! PREDICATE> | |
736 | ||
737 | Negate the sense of the following predicate. The C<!> must be passed as | |
738 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
739 | quoted from interpretation by the shell using a backslash (just as with | |
740 | using C<find(1)>). | |
741 | ||
742 | =item C<( PREDICATES )> | |
743 | ||
744 | Group the given PREDICATES. The parentheses must be passed as distinct | |
745 | arguments, so they may need to be surrounded by whitespace and/or | |
746 | quoted from interpretation by the shell using a backslash (just as with | |
747 | using C<find(1)>). | |
748 | ||
749 | =item C<PREDICATE1 PREDICATE2> | |
750 | ||
751 | True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not | |
752 | evaluated if PREDICATE1 is false. | |
753 | ||
754 | =item C<PREDICATE1 -o PREDICATE2> | |
755 | ||
756 | True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is | |
757 | not evaluated if PREDICATE1 is true. | |
758 | ||
759 | =item C<-follow> | |
760 | ||
3d1e7443 GS |
761 | Follow (dereference) symlinks. The checking of file attributes depends |
762 | on the position of the C<-follow> option. If it precedes the file | |
763 | check option, an C<stat> is done which means the file check applies to the | |
764 | file the symbolic link is pointing to. If C<-follow> option follows the | |
765 | file check option, this now applies to the symbolic link itself, i.e. | |
766 | an C<lstat> is done. | |
431613dd GS |
767 | |
768 | =item C<-depth> | |
769 | ||
770 | Change directory traversal algorithm from breadth-first to depth-first. | |
771 | ||
772 | =item C<-prune> | |
773 | ||
774 | Do not descend into the directory currently matched. | |
775 | ||
776 | =item C<-xdev> | |
777 | ||
778 | Do not traverse mount points (prunes search at mount-point directories). | |
779 | ||
780 | =item C<-name GLOB> | |
781 | ||
782 | File name matches specified GLOB wildcard pattern. GLOB may need to be | |
783 | quoted to avoid interpretation by the shell (just as with using | |
784 | C<find(1)>). | |
785 | ||
786 | =item C<-perm PERM> | |
787 | ||
788 | Low-order 9 bits of permission match octal value PERM. | |
789 | ||
790 | =item C<-perm -PERM> | |
791 | ||
792 | The bits specified in PERM are all set in file's permissions. | |
793 | ||
794 | =item C<-type X> | |
795 | ||
796 | The file's type matches perl's C<-X> operator. | |
797 | ||
798 | =item C<-fstype TYPE> | |
799 | ||
800 | Filesystem of current path is of type TYPE (only NFS/non-NFS distinction | |
801 | is implemented). | |
802 | ||
803 | =item C<-user USER> | |
804 | ||
805 | True if USER is owner of file. | |
806 | ||
807 | =item C<-group GROUP> | |
808 | ||
809 | True if file's group is GROUP. | |
810 | ||
811 | =item C<-nouser> | |
812 | ||
813 | True if file's owner is not in password database. | |
814 | ||
815 | =item C<-nogroup> | |
816 | ||
817 | True if file's group is not in group database. | |
818 | ||
819 | =item C<-inum INUM> | |
820 | ||
821 | True file's inode number is INUM. | |
822 | ||
823 | =item C<-links N> | |
824 | ||
825 | True if (hard) link count of file matches N (see below). | |
826 | ||
827 | =item C<-size N> | |
828 | ||
829 | True if file's size matches N (see below) N is normally counted in | |
830 | 512-byte blocks, but a suffix of "c" specifies that size should be | |
831 | counted in characters (bytes) and a suffix of "k" specifes that | |
832 | size should be counted in 1024-byte blocks. | |
833 | ||
834 | =item C<-atime N> | |
835 | ||
836 | True if last-access time of file matches N (measured in days) (see | |
837 | below). | |
838 | ||
839 | =item C<-ctime N> | |
840 | ||
841 | True if last-changed time of file's inode matches N (measured in days, | |
842 | see below). | |
843 | ||
844 | =item C<-mtime N> | |
845 | ||
846 | True if last-modified time of file matches N (measured in days, see below). | |
847 | ||
848 | =item C<-newer FILE> | |
849 | ||
850 | True if last-modified time of file matches N. | |
851 | ||
852 | =item C<-print> | |
853 | ||
9c4673c1 SR |
854 | Print out path of file (always true). If none of C<-exec>, C<-ls>, |
855 | C<-print0>, or C<-ok> is specified, then C<-print> will be added | |
856 | implicitly. | |
431613dd GS |
857 | |
858 | =item C<-print0> | |
859 | ||
860 | Like -print, but terminates with \0 instead of \n. | |
861 | ||
862 | =item C<-exec OPTIONS ;> | |
863 | ||
fb8eeed8 | 864 | exec() the arguments in OPTIONS in a subprocess; any occurrence of {} in |
431613dd GS |
865 | OPTIONS will first be substituted with the path of the current |
866 | file. Note that the command "rm" has been special-cased to use perl's | |
867 | unlink() function instead (as an optimization). The C<;> must be passed as | |
868 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
869 | quoted from interpretation by the shell using a backslash (just as with | |
870 | using C<find(1)>). | |
871 | ||
872 | =item C<-ok OPTIONS ;> | |
873 | ||
874 | Like -exec, but first prompts user; if user's response does not begin | |
875 | with a y, skip the exec. The C<;> must be passed as | |
876 | a distinct argument, so it may need to be surrounded by whitespace and/or | |
877 | quoted from interpretation by the shell using a backslash (just as with | |
878 | using C<find(1)>). | |
879 | ||
928e06a6 | 880 | =item C<-eval EXPR> |
431613dd | 881 | |
928e06a6 | 882 | Has the perl script eval() the EXPR. |
431613dd GS |
883 | |
884 | =item C<-ls> | |
885 | ||
886 | Simulates C<-exec ls -dils {} ;> | |
887 | ||
888 | =item C<-tar FILE> | |
889 | ||
890 | Adds current output to tar-format FILE. | |
891 | ||
892 | =item C<-cpio FILE> | |
893 | ||
894 | Adds current output to old-style cpio-format FILE. | |
895 | ||
896 | =item C<-ncpio FILE> | |
897 | ||
898 | Adds current output to "new"-style cpio-format FILE. | |
899 | ||
900 | =back | |
901 | ||
902 | Predicates which take a numeric argument N can come in three forms: | |
903 | ||
904 | * N is prefixed with a +: match values greater than N | |
905 | * N is prefixed with a -: match values less than N | |
906 | * N is not prefixed with either + or -: match only values equal to N | |
