module: file
version_added: historical
short_description: Manage files and file properties
extends_documentation_fragment: files
description:
- Set attributes of files, symlinks or directories.
- Alternatively, remove files, symlinks or directories.
- Many other modules support the same options as the C(file) module - including M(copy), M(template), and M(assemble).
- For Windows targets, use the M(win_file) module instead.
options:
path:
description:
- Path to the file being managed.
type: path
required: yes
aliases: [ dest, name ]
state:
description:
- If C(absent), directories will be recursively deleted, and files or symlinks will
be unlinked. In the case of a directory, if C(diff) is declared, you will see the files and folders deleted listed
under C(path_contents). Note that C(absent) will not cause C(file) to fail if the C(path) does
not exist as the state did not change.
- If C(directory), all intermediate subdirectories will be created if they
do not exist. Since Ansible 1.7 they will be created with the supplied permissions.
- If C(file), without any other options this works mostly as a 'stat' and will return the current state of C(path).
Even with other options (i.e C(mode)), the file will be modified but will NOT be created if it does not exist;
see the C(touch) value or the M(copy) or M(template) module if you want that behavior.
- If C(hard), the hard link will be created or changed.
- If C(link), the symbolic link will be created or changed.
- If C(touch) (new in 1.4), an empty file will be created if the C(path) does not
exist, while an existing file or directory will receive updated file access and
modification times (similar to the way C(touch) works from the command line).
type: str
default: file
choices: [ absent, directory, file, hard, link, touch ]
src:
description:
- Path of the file to link to.
- This applies only to C(state=link) and C(state=hard).
- For C(state=link), this will also accept a non-existing path.
- Relative paths are relative to the file being created (C(path)) which is how
the Unix command C(ln -s SRC DEST) treats relative paths.
type: path
recurse:
description:
- Recursively set the specified file attributes on directory contents.
- This applies only when C(state) is set to C(directory).
type: bool
default: no
version_added: '1.1'
force:
description:
- >
Force the creation of the symlinks in two cases: the source file does
not exist (but will appear later); the destination exists and is a file (so, we need to unlink the
C(path) file and create symlink to the C(src) file in place of it).
type: bool
default: no
follow:
description:
- This flag indicates that filesystem links, if they exist, should be followed.
- Previous to Ansible 2.5, this was C(no) by default.
type: bool
default: yes
version_added: '1.8'
modification_time:
description:
- This parameter indicates the time the file's modification time should be set to.
- Should be C(preserve) when no modification is required, C(YYYYMMDDHHMM.SS) when using default time format, or C(now).
- Default is None meaning that C(preserve) is the default for C(state=[file,directory,link,hard]) and C(now) is default for C(state=touch).
type: str
version_added: "2.7"
modification_time_format:
description:
- When used with C(modification_time), indicates the time format that must be used.
- Based on default Python format (see time.strftime doc).
type: str
default: "%Y%m%d%H%M.%S"
version_added: '2.7'
access_time:
description:
- This parameter indicates the time the file's access time should be set to.
- Should be C(preserve) when no modification is required, C(YYYYMMDDHHMM.SS) when using default time format, or C(now).
- Default is C(None) meaning that C(preserve) is the default for C(state=[file,directory,link,hard]) and C(now) is default for C(state=touch).
type: str
version_added: '2.7'
access_time_format:
description:
- When used with C(access_time), indicates the time format that must be used.
- Based on default Python format (see time.strftime doc).
type: str
default: "%Y%m%d%H%M.%S"
