# File timestamp
|
|
|
|
## atime
|
|
|
|
This timestamp indicates when a file was last accessed (read). `cat`ing
|
|
a file or executing a shellscript will set it, for example.
|
|
|
|
## ctime
|
|
|
|
This timestamp is set, whenever the metadata of a file (stored in the
|
|
responsible inode) is set. The metadata includes for example:
|
|
|
|
- file name
|
|
- fize size
|
|
- file mode (permissions)
|
|
|
|
and some other things. `ctime` will also be updated when a file is
|
|
written to (when `mtime` is updated.
|
|
|
|
## mtime
|
|
|
|
The mtime is set, whenever a file's contents are changed, for example
|
|
by editing a file.
