On my Fedora 19 system tab completion doesn't work for bash scripts when I have a sh at the beginning of the command line unless the script filename ends with a .sh.

That is, if I type:

$ sh file<tab>

And the current directory contains:

filename

...tab completion doesn't work.

But if the current directory contains:

filename.sh

Completion works.

Completion works for everything else, so I suspect that there is a custom completer for commands that begin with sh and it is looking for files that end .sh.

Is there an easy way to fix this? I want to fix it for my user, not for all users, because I don't want to modify the operating system.

As @AlexanderPoteriachin pointed out, if you type filename yourself and the file is named filename there nothing more to complete. Do you mean you type e.g. only filen and [TAB] is not working? –  mpy Jul 17 '13 at 11:36

The most basic commands to customize your completions in bash are:

  • To only complete .sh files after (G stands for globbing):

    complete -G '*.sh' sh
    

    Probably this is somewhere in your (system wide) config. (You can check with complete -pr which prints all definitions)

  • To complete any filename after sh just issue

    complete -A file sh
    

    -A takes much more possible actions (here: file), please check out the description of the complete builtin in man bashbuiltins for much more options.

For a permanent fix of that behavior, put the last command also to your ~/.bashrc.

Yep. That did the trick. Thanks! –  vy32 Jul 17 '13 at 21:54

No, there should be anything custom. Haven't seen on anything like that on any Linux version. The tab completion works as expected.

By the way, what is the point

$ sh filename<tab>

of that anyway if you have "filename" in your directory?

Maybe you're confused a little bit, as if you have two similar filenames in a directory, the completion only goes until the characters are the same and then it shows all available options.
