[Linux]How to use basename command in CentOS - strip directory and suffix from filenames

Purpose

Print NAME with any leading directory components removed. If specified, also remove a trailing SUFFIX.

파일명에서 접미사를 삭제할 때 사용한다.

나의 경우 gitlab restore 스크립트를 작성할 때 사용하였다.
backup 파일이 "1620209195_2021_05_05_13.2.0_gitlab_backup.tar" 와 같은 형식으로 떨어졌고, restore 명령어에서는 "_gitlab_backup.tar" 이 부분이 불필요하여 basename 명령어를 사용하여 해당 내용을 제거 하였다.
