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.
