SYNOPSIS touch [OPTION]... FILE... DESCRIPTION Update the access and modification times of each FILE to the current time. timestamp更新到当前时间,链接文件需要-h选项才可以 A FILE argument that does not exist is created empty, unless -c or -h is supplied. 文件不存在会被创建 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 改变文件的读取时间记录 -c, --no-create do not create any files 假如目标文件不存在,不会建立新的文件。与 --no-create 的效果一样 -d, --date=STRING parse STRING and use it instead of current time 指定时间,字符串的格式见后文 -f (ignored) <不使用,是为了与其他 unix 系统的相容性而保留 -h, --no-dereference affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink) 可以更改链接文件的timestamps -m change only the modification time 改变文件的修改时间记录 -r, --reference=FILE use this file's times instead of current time 使用参考文件的时间记录,与 --file 的效果一样 -t STAMP use [[CC]YY]MMDDhhmm[.ss] instead of current time --time=WORD change the specified time: WORD is access, atime, or use: equiv‐ alent 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 cal‐ endar date, time of day, time zone, day of week, relative time, rela‐ tive 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.
