The rm Command
rm stands for remove, and it is used to remove files, directories, and links. By default, it does not remove directories.
This command normally works silently and it should be used carefully, because once you delete a file in Linux the content cannot be recovered.
rm [OPTION]... FILE...
There are a couple of common options, which you might notice are similar to the options for both cp and mv.
|-i||Prompt before every removal.|
|-r, -R, --recursive||Remove directories and their contents recursively.|
The unlink command is very similar to the rm command, but only removes a single file at a time, and does not remove directories.
The touch Command
The touch command updates the access and modification times of each file to the current time. The touch command is a standard command in Linux used to create, change, and modify the timestamp of a file. If the file specified does not exist touch will create the file, but the file does not have any content.
|-a||Change only the access time.|
|-c, --no-create||Do not create any files.|
|-d, --date=STRING||Parse STRING and use it instead of current time.|
|-h, --no-dereference||Affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink).|
|-m||Change only the modification time.|
|-r, --reference=FILE||Use this file's times instead of current time.|
|-t STAMP||Use [[CC]YY]MMDDhhmm[.ss] instead of current time.|
|--time=WORD||Change the specified time: WORD is access, atime, or use: equivalent to -a WORD is modify or mtime.|
