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

928e06a6 | 860 | =item C<-eval EXPR> |
431613dd | 861 | |
928e06a6 | 862 | Has the perl script eval() the EXPR. |

868 | =item C<-tar FILE> | |
869 | ||
870 | Adds current output to tar-format FILE. | |
871 | ||
872 | =item C<-cpio FILE> | |
873 | ||
874 | Adds current output to old-style cpio-format FILE. | |

876 | =item C<-ncpio FILE> | |
877 | ||
878 | Adds current output to "new"-style cpio-format FILE. | |

882 | Predicates which take a numeric argument N can come in three forms: | |
883 | ||
884 | * N is prefixed with a +: match values greater than N | |
885 | * N is prefixed with a -: match values less than N | |
886 | * N is not prefixed with either + or -: match only values equal to N | |
