The touch Command.

Using touch Command A FILE argument that does not exist is created empty, unless -c or -h is supplied.

Examples

  1. To make a new text file use the following command, and if it does not already exist a new file will be created or overwritten otherwise.
touch file.txt
  1. Touch command to create multiple files: Touch command can be used to create the multiple numbers of files at the same time. These files would be empty while creation.
touch File1_name File2_name File3_name

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.

  1. -a

change only the access time

  1. -c, --no-create

do not create any files

  1. -d, --date=STRING

parse STRING and use it instead of current time

  1. -f

(ignored)

  1. -h, --no-dereference

affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink)

  1. -m

change only the modification time

  1. -r, --reference=FILE

use this file's times instead of current time

  1. -t STAMP

use [[CC]YY]MMDDhhmm[.ss] instead of current time

  1. --time=WORD

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

  1. --help

display this help and exit

  1. --version

output version information and exit

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