touch – change file timestamps
touch [OPTION]… FILE…
Update the access and modification times of each FILE to the current time.
A FILE argument that does not exist is created empty.
A FILE argument string of – is handled specially and causes touch to change the times of the file associated with standard output.
Mandatory arguments to long options are mandatory for short options too.
- change only the access time
- -c, –no-create
- do not create any files
- -d, –date=STRING
- parse STRING and use it instead of current time
- change only the modification time
- -r, –reference=FILE
- use this file’s times instead of current time
- -t STAMP
- use [[CC]YY]MMDDhhmm[.ss] instead of current time
- change the specified time: WORD is access, atime, or use: equivalent to -a WORD is modify or mtime: equivalent to -m
- display this help and exit
- output version information and exit
Note that the -d and -t options accept different time-date formats.
