   touch    ( 1 )

изменить временные метки файла (change file timestamps)

Имя (Name)

touch - change file timestamps

Синопсис (Synopsis)

touch [OPTION]... FILE...

Описание (Description)

Update the access and modification times of each FILE to the
       current time.

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.

-a 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

-f (ignored)

-h, --no-dereference affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink)

-m 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

--time=WORD change the specified time: WORD is access, atime, or use: equivalent to -a WORD is modify or mtime: equivalent to -m

--help display this help and exit

--version output version information and exit

Note that the -d and -t options accept different time-date formats.


DATE STRING

The --date=STRING is a mostly free format human readable date
       string such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29
       16:21:42" or even "next Thursday".  A date string may contain
       items indicating calendar date, time of day, time zone, day of
       week, relative time, relative date, and numbers.  An empty string
       indicates the beginning of the day.  The date string format is
       more complex than is easily documented here but is fully
       described in the info documentation.
