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'' specifies 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
