Linux touch command
Linux touch command is used to create empty files or change time stamp for existing files.
For this example, first, check the number of files available in the current directory. I have one file in our directory as below
$ ls -l -rw-r--r-- 1 root root 656 Dec 28 2015 testfile.doc
Check the modification date of existing file and create a new file myfile.txt using touch command. Also, try touch command with the existing file.
$ touch myfile.txt $ touch testfile.doc
Again list the files in current directory. You can see a new empty file created and existing file modification time is changed to current date/time.
$ ls -l -rw-r--r-- 1 root root 0 Sep 5 14:37 myfile.txt -rwxr-xr-x 1 root root 104 Sep 5 14:38 testfile.doc
