A FILE argument that does not exist is created empty, unless -c or -h is supplied.
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
- -h, --no-dereference
- affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink)
- 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.
