NAME

     find2perl - translate find command lines to Perl code



SYNOPSIS
             find2perl [paths] [predicates] | perl




DESCRIPTION
     find2perl is a little translator to convert find command
     lines to equivalent Perl code.  The resulting code is
     typically faster than running find itself.

     "paths" are a set of paths where find2perl will start its
     searches and "predicates" are taken from the following list.

     `! PREDICATE'
         Negate the sense of the following predicate.  The `!'
         must be passed as a distinct argument, so it may need to
         be surrounded by whitespace and/or quoted from
         interpretation by the shell using a backslash (just as
         with using `find(1)').

     `( PREDICATES )'
         Group the given PREDICATES.  The parentheses must be
         passed as distinct arguments, so they may need to be
         surrounded by whitespace and/or quoted from
         interpretation by the shell using a backslash (just as
         with using `find(1)').

     `PREDICATE1 PREDICATE2'
         True if _both_ PREDICATE1 and PREDICATE2 are true;
         PREDICATE2 is not evaluated if PREDICATE1 is false.

     `PREDICATE1 -o PREDICATE2'
         True if either one of PREDICATE1 or PREDICATE2 is true;
         PREDICATE2 is not evaluated if PREDICATE1 is true.

     `-follow'
         Follow (dereference) symlinks.  The checking of file
         attributes depends on the position of the `-follow'
         option. If it precedes the file check option, an `stat'
         is done which means the file check applies to the file
         the symbolic link is pointing to. If `-follow' option
         follows the file check option, this now applies to the
         symbolic link itself, i.e.  an `lstat' is done.

     `-depth'
         Change directory traversal algorithm from breadth-first
         to depth-first.

     `-prune'
         Do not descend into the directory currently matched.

     `-xdev'
         Do not traverse mount points (prunes search at mount-
         point directories).

     `-name GLOB'
         File name matches specified GLOB wildcard pattern.  GLOB
         may need to be quoted to avoid interpretation by the
         shell (just as with using `find(1)').

     `-perm PERM'
         Low-order 9 bits of permission match octal value PERM.

     `-perm -PERM'
         The bits specified in PERM are all set in file's
         permissions.

     `-type X'
         The file's type matches perl's `-X' operator.

     `-fstype TYPE'
         Filesystem of current path is of type TYPE (only
         NFS/non-NFS distinction is implemented).

     `-user USER'
         True if USER is owner of file.

     `-group GROUP'
         True if file's group is GROUP.

     `-nouser'
         True if file's owner is not in password database.

     `-nogroup'
         True if file's group is not in group database.

     `-inum INUM'
         True file's inode number is INUM.

     `-links N'
         True if (hard) link count of file matches N (see below).

     `-size N'
         True if file's size matches N (see below) N is normally
         counted in 512-byte blocks, but a suffix of "c"
         specifies that size should be counted in characters
         (bytes) and a suffix of "k" specifes that size should be
         counted in 1024-byte blocks.

     `-atime N'
         True if last-access time of file matches N (measured in
         days) (see below).

     `-ctime N'
         True if last-changed time of file's inode matches N
         (measured in days, see below).

     `-mtime N'
         True if last-modified time of file matches N (measured
         in days, see below).

     `-newer FILE'
         True if last-modified time of file matches N.

     `-print'
         Print out path of file (always true).

     `-print0'
         Like -print, but terminates with \0 instead of \n.

     `-exec OPTIONS ;'
         exec() the arguments in OPTIONS in a subprocess; any
         occurence of {} in OPTIONS will first be substituted
         with the path of the current file.  Note that the
         command "rm" has been special-cased to use perl's
         unlink() function instead (as an optimization).  The `;'
         must be passed as a distinct argument, so it may need to
         be surrounded by whitespace and/or quoted from
         interpretation by the shell using a backslash (just as
         with using `find(1)').

     `-ok OPTIONS ;'
         Like -exec, but first prompts user; if user's response
         does not begin with a y, skip the exec.  The `;' must be
         passed as a distinct argument, so it may need to be
         surrounded by whitespace and/or quoted from
         interpretation by the shell using a backslash (just as
         with using `find(1)').

     `-eval EXPR'
         Has the perl script eval() the EXPR.

     `-ls'
         Simulates `-exec ls -dils {} ;'

     `-tar FILE'
         Adds current output to tar-format FILE.

     `-cpio FILE'
         Adds current output to old-style cpio-format FILE.

     `-ncpio FILE'
         Adds current output to "new"-style cpio-format FILE.


     Predicates which take a numeric argument N can come in three
     forms:

        * N is prefixed with a +: match values greater than N
        * N is prefixed with a -: match values less than N
        * N is not prefixed with either + or -: match only values equal to N
