| 718 | =head1 NAME
|
|---|
| 719 |
|
|---|
| 720 | find2perl - translate find command lines to Perl code
|
|---|
| 721 |
|
|---|
| 722 | =head1 SYNOPSIS
|
|---|
| 723 |
|
|---|
| 724 | find2perl [paths] [predicates] | perl
|
|---|
| 725 |
|
|---|
| 726 | =head1 DESCRIPTION
|
|---|
| 727 |
|
|---|
| 728 | find2perl is a little translator to convert find command lines to
|
|---|
| 729 | equivalent Perl code. The resulting code is typically faster than
|
|---|
| 730 | running 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 |
|
|---|
| 739 | Negate the sense of the following predicate. The C<!> must be passed as
|
|---|
| 740 | a distinct argument, so it may need to be surrounded by whitespace and/or
|
|---|
| 741 | quoted from interpretation by the shell using a backslash (just as with
|
|---|
| 742 | using C<find(1)>).
|
|---|
| 743 |
|
|---|
| 744 | =item C<( PREDICATES )>
|
|---|
| 745 |
|
|---|
| 746 | Group the given PREDICATES. The parentheses must be passed as distinct
|
|---|
| 747 | arguments, so they may need to be surrounded by whitespace and/or
|
|---|
| 748 | quoted from interpretation by the shell using a backslash (just as with
|
|---|
| 749 | using C<find(1)>).
|
|---|
| 750 |
|
|---|
| 751 | =item C<PREDICATE1 PREDICATE2>
|
|---|
| 752 |
|
|---|
| 753 | True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not
|
|---|
| 754 | evaluated if PREDICATE1 is false.
|
|---|
| 755 |
|
|---|
| 756 | =item C<PREDICATE1 -o PREDICATE2>
|
|---|
| 757 |
|
|---|
| 758 | True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is
|
|---|
| 759 | not evaluated if PREDICATE1 is true.
|
|---|
| 760 |
|
|---|
| 761 | =item C<-follow>
|
|---|
| 762 |
|
|---|
| 763 | Follow (dereference) symlinks. The checking of file attributes depends
|
|---|
| 764 | on the position of the C<-follow> option. If it precedes the file
|
|---|
| 765 | check option, an C<stat> is done which means the file check applies to the
|
|---|
| 766 | file the symbolic link is pointing to. If C<-follow> option follows the
|
|---|
| 767 | file check option, this now applies to the symbolic link itself, i.e.
|
|---|
| 768 | an C<lstat> is done.
|
|---|
| 769 |
|
|---|
| 770 | =item C<-depth>
|
|---|
| 771 |
|
|---|
| 772 | Change directory traversal algorithm from breadth-first to depth-first.
|
|---|
| 773 |
|
|---|
| 774 | =item C<-prune>
|
|---|
| 775 |
|
|---|
| 776 | Do not descend into the directory currently matched.
|
|---|
| 777 |
|
|---|
| 778 | =item C<-xdev>
|
|---|
| 779 |
|
|---|
| 780 | Do not traverse mount points (prunes search at mount-point directories).
|
|---|
| 781 |
|
|---|
| 782 | =item C<-name GLOB>
|
|---|
| 783 |
|
|---|
| 784 | File name matches specified GLOB wildcard pattern. GLOB may need to be
|
|---|
| 785 | quoted to avoid interpretation by the shell (just as with using
|
|---|
| 786 | C<find(1)>).
|
|---|
| 787 |
|
|---|
| 788 | =item C<-iname GLOB>
|
|---|
| 789 |
|
|---|
| 790 | Like C<-name>, but the match is case insensitive.
|
|---|
| 791 |
|
|---|
| 792 | =item C<-path GLOB>
|
|---|
| 793 |
|
|---|
| 794 | Path name matches specified GLOB wildcard pattern.
|
|---|
| 795 |
|
|---|
| 796 | =item C<-ipath GLOB>
|
|---|
| 797 |
|
|---|
| 798 | Like C<-path>, but the match is case insensitive.
|
|---|
| 799 |
|
|---|
| 800 | =item C<-perm PERM>
|
|---|
| 801 |
|
|---|
| 802 | Low-order 9 bits of permission match octal value PERM.
|
|---|
| 803 |
|
|---|
| 804 | =item C<-perm -PERM>
|
|---|
| 805 |
|
|---|
| 806 | The bits specified in PERM are all set in file's permissions.
|
|---|
| 807 |
|
|---|
| 808 | =item C<-type X>
|
|---|
| 809 |
|
|---|
| 810 | The file's type matches perl's C<-X> operator.
|
|---|
| 811 |
|
|---|
| 812 | =item C<-fstype TYPE>
|
|---|
| 813 |
|
|---|
| 814 | Filesystem of current path is of type TYPE (only NFS/non-NFS distinction
|
|---|
| 815 | is implemented).
|
|---|
| 816 |
|
|---|
| 817 | =item C<-user USER>
|
|---|
| 818 |
|
|---|
| 819 | True if USER is owner of file.
|
|---|
| 820 |
|
|---|
| 821 | =item C<-group GROUP>
|
|---|
| 822 |
|
|---|
| 823 | True if file's group is GROUP.
|
|---|
| 824 |
|
|---|
| 825 | =item C<-nouser>
|
|---|
| 826 |
|
|---|
| 827 | True if file's owner is not in password database.
|
|---|
| 828 |
|
|---|
| 829 | =item C<-nogroup>
|
|---|
| 830 |
|
|---|
| 831 | True if file's group is not in group database.
|
|---|
| 832 |
|
|---|
| 833 | =item C<-inum INUM>
|
|---|
| 834 |
|
|---|
| 835 | True file's inode number is INUM.
|
|---|
| 836 |
|
|---|
| 837 | =item C<-links N>
|
|---|
| 838 |
|
|---|
| 839 | True if (hard) link count of file matches N (see below).
|
|---|
| 840 |
|
|---|
| 841 | =item C<-size N>
|
|---|
| 842 |
|
|---|
| 843 | True if file's size matches N (see below) N is normally counted in
|
|---|
| 844 | 512-byte blocks, but a suffix of "c" specifies that size should be
|
|---|
| 845 | counted in characters (bytes) and a suffix of "k" specifes that
|
|---|
| 846 | size should be counted in 1024-byte blocks.
|
|---|
| 847 |
|
|---|
| 848 | =item C<-atime N>
|
|---|
| 849 |
|
|---|
| 850 | True if last-access time of file matches N (measured in days) (see
|
|---|
| 851 | below).
|
|---|
| 852 |
|
|---|
| 853 | =item C<-ctime N>
|
|---|
| 854 |
|
|---|
| 855 | True if last-changed time of file's inode matches N (measured in days,
|
|---|
| 856 | see below).
|
|---|
| 857 |
|
|---|
| 858 | =item C<-mtime N>
|
|---|
| 859 |
|
|---|
| 860 | True if last-modified time of file matches N (measured in days, see below).
|
|---|
| 861 |
|
|---|
| 862 | =item C<-newer FILE>
|
|---|
| 863 |
|
|---|
| 864 | True if last-modified time of file matches N.
|
|---|
| 865 |
|
|---|
| 866 | =item C<-print>
|
|---|
| 867 |
|
|---|
| 868 | Print out path of file (always true). If none of C<-exec>, C<-ls>,
|
|---|
| 869 | C<-print0>, or C<-ok> is specified, then C<-print> will be added
|
|---|
| 870 | implicitly.
|
|---|
| 871 |
|
|---|
| 872 | =item C<-print0>
|
|---|
| 873 |
|
|---|
| 874 | Like -print, but terminates with \0 instead of \n.
|
|---|
| 875 |
|
|---|
| 876 | =item C<-exec OPTIONS ;>
|
|---|
| 877 |
|
|---|
| 878 | exec() the arguments in OPTIONS in a subprocess; any occurrence of {} in
|
|---|
| 879 | OPTIONS will first be substituted with the path of the current
|
|---|
| 880 | file. Note that the command "rm" has been special-cased to use perl's
|
|---|
| 881 | unlink() function instead (as an optimization). The C<;> must be passed as
|
|---|
| 882 | a distinct argument, so it may need to be surrounded by whitespace and/or
|
|---|
| 883 | quoted from interpretation by the shell using a backslash (just as with
|
|---|
| 884 | using C<find(1)>).
|
|---|
| 885 |
|
|---|
| 886 | =item C<-ok OPTIONS ;>
|
|---|
| 887 |
|
|---|
| 888 | Like -exec, but first prompts user; if user's response does not begin
|
|---|
| 889 | with a y, skip the exec. The C<;> must be passed as
|
|---|
| 890 | a distinct argument, so it may need to be surrounded by whitespace and/or
|
|---|
| 891 | quoted from interpretation by the shell using a backslash (just as with
|
|---|
| 892 | using C<find(1)>).
|
|---|
| 893 |
|
|---|
| 894 | =item C<-eval EXPR>
|
|---|
| 895 |
|
|---|
| 896 | Has the perl script eval() the EXPR.
|
|---|
| 897 |
|
|---|
| 898 | =item C<-ls>
|
|---|
| 899 |
|
|---|
| 900 | Simulates C<-exec ls -dils {} ;>
|
|---|
| 901 |
|
|---|
| 902 | =item C<-tar FILE>
|
|---|
| 903 |
|
|---|
| 904 | Adds current output to tar-format FILE.
|
|---|
| 905 |
|
|---|
| 906 | =item C<-cpio FILE>
|
|---|
| 907 |
|
|---|
| 908 | Adds current output to old-style cpio-format FILE.
|
|---|
| 909 |
|
|---|
| 910 | =item C<-ncpio FILE>
|
|---|
| 911 |
|
|---|
| 912 | Adds current output to "new"-style cpio-format FILE.

| 913 |
|
|---|
| 914 | =back
|
|---|
| 915 |
|
|---|
| 916 | Predicates 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
