find2perl - translate find command lines to Perl code
- find2perl [paths] [predicates] | perl
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
