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. =over 4 =item C<! PREDICATE> Negate the sense of the following predicate. The C<!> 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 C<find(1)>). =item C<( 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 C<find(1)>). =item C<PREDICATE1 PREDICATE2> True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not evaluated if PREDICATE1 is false. =item C<PREDICATE1 -o PREDICATE2> True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is not evaluated if PREDICATE1 is true. =item C<-follow> Follow (dereference) symlinks. The checking of file attributes depends on the position of the C<-follow> option. If it precedes the file check option, an C<stat> is done which means the file check applies to the file the symbolic link is pointing to. If C<-follow> option follows the file check option, this now applies to the symbolic link itself, i.e. an C<lstat> is done. =item C<-depth> Change directory traversal algorithm from breadth-first to depth-first. =item C<-prune> Do not descend into the directory currently matched. =item C<-xdev> Do not traverse mount points (prunes search at mount-point directories). =item C<-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 C<find(1)>). =item C<-iname GLOB> Like C<-name>, but the match is case insensitive. =item C<-path GLOB> Path name matches specified GLOB wildcard pattern. =item C<-ipath GLOB> Like C<-path>, but the match is case insensitive. =item C<-perm PERM> Low-order 9 bits of permission match octal value PERM. =item C<-perm -PERM> The bits specified in PERM are all set in file's permissions. =item C<-type X> The file's type matches perl's C<-X> operator. =item C<-fstype TYPE> Filesystem of current path is of type TYPE (only NFS/non-NFS distinction is implemented). =item C<-user USER> True if USER is owner of file. =item C<-group GROUP> True if file's group is GROUP. =item C<-nouser> True if file's owner is not in password database. =item C<-nogroup> True if file's group is not in group database. =item C<-inum INUM> True file's inode number is INUM. =item C<-links N> True if (hard) link count of file matches N (see below). =item C<-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" specifies that size should be counted in 1024-byte blocks. =item C<-atime N> True if last-access time of file matches N (measured in days) (see below). =item C<-ctime N> True if last-changed time of file's inode matches N (measured in days, see below). =item C<-mtime N> True if last-modified time of file matches N (measured in days, see below). =item C<-newer FILE> True if last-modified time of file matches N. =item C<-print> Print out path of file (always true). If none of C<-exec>, C<-ls>, C<-print0>, or C<-ok> is specified, then C<-print> will be added implicitly. =item C<-print0> Like -print, but terminates with \0 instead of \n. =item C<-exec OPTIONS ;> exec() the arguments in OPTIONS in a subprocess; any occurrence 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 C<;> 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 C<find(1)>). =item C<-ok OPTIONS ;> Like -exec, but first prompts user; if user's response does not begin with a y, skip the exec. The C<;> 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 C<find(1)>). =item C<-eval EXPR> Has the perl script eval() the EXPR. =item C<-ls> Simulates C<-exec ls -dils {} ;> =item C<-tar FILE> Adds current output to tar-format FILE. =item C<-cpio FILE> Adds current output to old-style cpio-format FILE. =item C<-ncpio FILE> Adds current output to "new"-style cpio-format FILE. =back 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 =head1 SEE ALSO find, File::Find. =cut
