I use the command line everyday at for work and home. Command switches a part of life but the problem is remembering switches. The man files have always helped and always will continue doing so.
Bash-completion came along to help in this area. It displays a list of a available switched for a specific command by simply hitting the TAB key twice. See screenshots below for clearer picture.
Download the rpm . Currently no packages available from the CentOS repos.
Install the rpm
#“rpm -ivh bash-completion-20060301-1.noarch.rpm”
Start a new shell or execute the command below
Test out your new shell enhancement
#“ls — [TAB][TAB]"
