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
