Usage

zzfind [ option ] ... file-or-dir ... [ expression ]

Apply "expression" to "file-or-dir ..." and all nested directory members, archive entries and compressed files.

File name "-" stands for STDIN.

Options

--help

Print this text and terminate.

--look-into format-glob:path-glob

Look into compressed and archive contents if the format and the path match the globs. The default is to look into any recognised archive or compressed contents.
Supported archive formats in this runtime configuration are:
${archive.formats}
Supported compression formats in this runtime configuration are:
${compression.formats}

--depth

Process each directory's contents before the directory itself, and each archive's entries before the archive itself, and each compressed contents before the enclosing file or archive entry.

--min-depth levels

Do not apply any tests or actions at levels less than levels. E.g. "1" means "process all files except the top level files and directories".

--max-depth levels

Descend at most levels of directories below the top level files and directories. "0" means "only apply the tests and actions to the top level files and directories".

If in doubt, try:

zzfind ... -print -echo @{depth}

--nowarn

Suppress all messages except errors.

--quiet

Suppress normal output.

--verbose

Print verbose messages.

--debug

Print verbose and debug messages.

--log level:logger:handler:formatter:format

Add logging at level FINE on logger "de.unkrig" to STDERR using the "FormatFormatter" and "SIMPLE" format, or the given arguments, which are all optional.

-zip

-zz

-nested-zip

-z

(These are no longer supported; use "--look-into" instead.)

Expressions

Tests

-name glob

Name matches "glob" (see below).

-path glob

The full path (e.g. "dir/file.zip!dir/file.zip!dir/file" or "dir/file") matches "glob" (see below).

-type glob

Whether the type matches the glob. See the "type" property, described below. If you are unsure about types, run zzfind with -echo "@{type} @{path}" first.

-readable

Whether this file is readable.

-writable

Whether this file is writable.

-executable

Whether this file is executable.

-size N

-size -N

-size +N

Whether the size is exactly/less than/more than N (e.g. "100", "-1K", "+10M").

-mtime N

-mtime +N

-mtime -N

Whether this file/archive entry was last modified (exactly/more than/less than) N days ago (N=0: 0...24h, N=1: 24...48h, ...).

-mmin N

-mmin +N

-mmin -N

Whether this file/archive entry was last modified (exactly/more than/less than) N minutes ago (N=0: 0...59sec, N=1: 60...119sec, ...).

exp1 -a exp2

exp1 exp2

Whether both exp1 and exp2 are true. exp2 is not evaluated if exp1 is false.

exp1 -o exp2

Whether exp1 or exp2 is true. exp2 is not evaluated if exp1 is true.

exp1 , exp2

Evaluates both expressions and returns the result of exp2.

-not exp

! exp

Whether exp is false.

( exp )

Whether exp is true.

Actions

-print

Print file path and return true.

-echo message

Print the message and return true. All occurrences of "@{property-name}" in the message are replaced with the value of the property. For the list of supported properties, see section "Properties of files and archive entries", below.

-ls

Print file type, readability, writability, executability, size, modification time and path, and return true.

-exec word... ;

Execute "word..." as an external command; "{}" is replaced with the current file's path (which may contain "!" and would then NOT denote a physical file in the file system).

-pipe word... ;

Copy the file contents to the standard input of an external command "word..."; "{}" is replaced with the current file's path (which may contain "!" and would then NOT denote a physical file in the file system).

-cat

Print file contents and return true.

-copy tofile

Copy file contents to the named file. All occurrences of "@{property-name}" in the tofile are replaced with the value of the property. For the list of supported properties, see section "Properties of files and archive entries", below.

-disassemble [ -hideLines ] [ -hideVars ]

Disassembles a Java class file.

-digest algorithm

Calculate a "message digest" of the contents, print it and return true.
Algorithms available in this environment are: ${digest.providers}

-checksum CRC32|ADLER32

Calculate a checksum of the contents, print it and return true.

-true

Return true.

-false

Return false.

If no action is given, then "-print" is implicitly added.

Properties of files and archive entries

Various tests and actions (e.g. "-echo") have access to a set of "properties" of the current file or archive entry.

"name":

The last component of the path.

"path":

The path to the resources as it was found. "!" indicates an archive, "%" a compressed file.

"depth":

Zero for the files/directories specified on the command line, +1 for files/directories in a subdirectory, +1 for compressed content, and +1 for the entries of archive files.

"type":

The "type" of the current subject; the actual types are:

directory

A directory

file

A (non-archive, not-compressed) file

archive-file

compressed-file

A compressed file

archive

A nested archive

normal-contents

Normal (non-archive, not-compressed) content

directory-entry

A "directory entry" in an archive.

"absolutePath":

The absolute path of the file or directory, typically by resolving relative paths against the current user directory. For all other types: That of the enclosing file.
