Change a file access and modification times (atime, mtime). More information: <https://www.gnu.org/software/coreutils/touch>.

• Create a new empty file(s) or change the times for existing file(s) to current time:
  touch path/to/file
• Set the times on a file to a specific date and time:
  touch -t YYYYMMDDHHMM.SS path/to/file
• Set the time on a file to one hour in the past:
  touch -d "-1 hour" path/to/file
• Use the times from a file to set the times on a second file:
  touch -r path/to/file1 path/to/file2
• Create multiple files:
  touch path/to/file{1,2,3}.txt
