I bind the "menu-complete" command to <TAB> key with the following line in my .bashrc: bind '"\t"':menu-complete
menu-complete is a bash command. It allows to bash to display in a different way completions. Instead of display a list of completion, possible completions rolls on your current line. I am pretty sure that the problem comes from bash, not bash-completion. Setting bash to verbose, auto_completion commands seem the same with "complete" (standard completion) and "menu-complete". menu-complete is not able to complete file names. However, it can complete directories names. Here to reproduce: $ mkdir bar1 bar2 $ touch foo1 foo2 $ ls ba<TAB> $ ls bar1/ # OK $ ls fo<TAB> # nothing append Jérôme
