Tab completion is awesome. It helps to quickly call commands without typing it entirely. For example in my home directory there is the directory Downloads. If I want to change into it in a Bash-shell I simply have to enter cd Dow [tab]. After the tab-press the directory name is completed automatically. To enable this feature you have to install the appropriate package. In Feodra it is bash-completion, most distributions call the package similar.
However, sometimes there are more choices:
$ cd Do Dokumente/ Downloads/
In that case tab has to be pressed two times to unveil the two options. To have both options already on the first tab, create the file ~/.inputrc and enter the lines
set show-all-if-ambiguous on
As usual, if you have other useful and short tips regarding Bash or the command line please let me know.
(Yes, I know about zsh’s great completion tool. Yes, I already used zsh quite some time. No, a tip how to set up Bash/ZSH with a fifty lines bashrc/zshrc is not suited for a comment here.)
