Also, it represents that if the file recognized doesn't exist, the file is made, and the modification and access times are fixed as specified. The file is recognized by a pathname imported as one argument. SUS (Single Unix Specification) defines that the touch command should modify the modification times, access times, or both for the files. Also, the touch command can be helpful to quickly create files for scripts or programs that need a file with a particular name to be available for successful program operation but don't need the file to include any specific content.These programs are typically only focused on files which have been modified or created after the program was last executed.An updated modification or access date can be important for a range of other programs like backup utilities or make command-line interface programming utilities.Rather it updates the dates related to the directory or file. The touch command ignores closing, saving, and opening the file.It is the same as opening or creating a file and storing it without any notification to the file contents in its default usage.Also, the command is available for Microsoft Windows and FreeDOS. It is available in ReactOS, Unix, TSC's FLEX, Unix-like operating systems, the Microware OS-9 shell, the AROS shell, and Digital Research/Novell DR DOS.
