module: find
author: Brian Coca (based on Ruggero Marchei's Tidy)
version_added: "2.0"
short_description: Return a list of files based on specific criteria
description:
- Return a list of files based on specific criteria. Multiple criteria are AND'd together.
- For Windows targets, use the M(win_find) module instead.
options:
age:
description:
- Select files whose age is equal to or greater than the specified time.
Use a negative age to find files equal to or less than the specified time.
You can choose seconds, minutes, hours, days, or weeks by specifying the
first letter of any of those words (e.g., "1w").
patterns:
default: '*'
description:
- One or more (shell or regex) patterns, which type is controlled by C(use_regex) option.
- The patterns restrict the list of files to be returned to those whose basenames match at
least one of the patterns specified. Multiple patterns can be specified using a list.
aliases: ['pattern']
excludes:
description:
- One or more (shell or regex) patterns, which type is controlled by C(use_regex) option.
- Items matching an C(excludes) pattern are culled from C(patterns) matches.
Multiple patterns can be specified using a list.
aliases: ['exclude']
version_added: "2.5"
contains:
description:
- One or more regex patterns which should be matched against the file content.
paths:
required: true
aliases: [ name, path ]
description:
- List of paths of directories to search. All paths must be fully qualified.
file_type:
description:
- Type of file to select.
- The 'link' and 'any' choices were added in version 2.3.
choices: [ any, directory, file, link ]
default: file
recurse:
description:
- If target is a directory, recursively descend into the directory looking for files.
type: bool
default: 'no'
size:
description:
- Select files whose size is equal to or greater than the specified size.
Use a negative size to find files equal to or less than the specified size.
Unqualified values are in bytes but b, k, m, g, and t can be appended to specify
bytes, kilobytes, megabytes, gigabytes, and terabytes, respectively.
Size is not evaluated for directories.
age_stamp:
default: mtime
choices: [ atime, ctime, mtime ]
description:
- Choose the file property against which we compare age.
hidden:
description:
- Set this to true to include hidden files, otherwise they'll be ignored.
type: bool
default: 'no'
follow:
description:
- Set this to true to follow symlinks in path for systems with python 2.6+.
type: bool
default: 'no'
get_checksum:
description:
- Set this to true to retrieve a file's sha1 checksum.
type: bool
default: 'no'
use_regex:
description:
- If false, the patterns are file globs (shell). If true, they are python regexes.
type: bool
default: 'no'
depth:
description:
- Set the maximum number of levels to decend into. Setting recurse
to false will override this value, which is effectively depth 1.
Default is unlimited depth.
version_added: "2.6"
notes:
- For Windows targets, use the M(win_find) module instead.
