										 |  |  | ``` | 
					
						
							|  |  |  | touch [options] filename |

 | 
					
						
							|  |  |  | Commonly used options: | 
					
						
							|  |  |  | - `-t` change timestamp to specific date ((YYYYMMDDHHMM.SS)) instead of current time. | 
					
						
							|  |  |  | - `-r` use timestamp from first file to second file. |

										 |  |  | - `-a` In case you want to only change the access time, use the -a command line option. | 
					
						
							|  |  |  | - `-m` Similarly, if the requirement is to only change the modification time, use the -m command line option. |
