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)).
-iname GLOB
Like "-name", but the match is case insensitive.
-path GLOB
Path name matches specified GLOB wildcard pattern.
-ipath GLOB
Like "-path", but the match is case insensitive.
-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). If none of "-exec", "-ls", "-print0", or "-ok" is specified, then "-print" will be added implicitly.
-print0
Like -print, but terminates with \0 instead of \n.
-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 ";" 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
