如何使 bash 选项卡完成的行为类似于 vim 选项卡完成并循环匹配匹配项？

Question

I've been meaning to find a solution for this for YEARS.

I am sooo much more productive in vim when manipulating files than bash for this reason.

If I have

file_12390983421
file_12391983421
file_12340983421
file_12390986421

In bash and type file_1->tab , it obviously lists:

file_12390983421 file_12391983421 file_12340983421 file_12390986421

And this is a horrible bore and painful to work with.

The same sequence in vim will loop through the files one at a time.

Please someone tell me how to do this in bash, or if there is another shell that can do this, I'll switch tomorrow.

Answer 1

By default TAB is bound to the complete readline command. Your desired behavior would be menu-complete instead. You can change your readlines settings by editing ~/.inputrc . To rebind TAB , add this line:

TAB: menu-complete

For more details see the READLINE section in man bash .

Answer 2

For bash >= 4 you might like these settings. You can try them directly on the command-line, and put them in your .bashrc if you like them.

# If there are multiple matches for completion, Tab should cycle through them

bind 'TAB':menu-complete

# Display a list of the matching files

bind "set show-all-if-ambiguous on"

# Perform partial completion on the first Tab press,
# only start cycling full results on the second Tab press

bind "set menu-complete-display-prefix on"

This setup is similar to Vim's set wildmode=longest:full:list,full

I pulled these settings from this question on the Unix & Linux site.

By the way, since you are here, here is another nice pair of bindings:

# Cycle through history based on characters already typed on the line

bind '"\e[A":history-search-backward'
bind '"\e[B":history-search-forward'

This means if you type ssh<Up> it will cycle through previous lines where you ran ssh

If you don't like what you got, you can clear the line with Ctrl-K Ctrl-U

I pulled these settings from this question on AskUbuntu.

Answer 3

On top of

# cycle forward
Control-k: menu-complete
# cycle backward
Control-j: menu-complete-backward

you may also consider adding

# display one column with matches
set completion-display-width 1

This way you would preserve the current Tab functionality and make bash display the possibilities in one column. So instead of

file_12340983421 file_12390983421 file_12390986421 file_12391983421

you would get

file_12340983421
file_12390983421
file_12390986421
file_12391983421

PS You can get up to date readline library from this The GNU Readline Library website.

Answer 4

Thanks to @sth I found what works best for me:

To keep normal bash tab completion, and then use ctl-f to cycle through when needed using menu-complete

put this in your .inputrc file:

"\C-f": menu-complete

Answer 5

In my experience, the solution provided in sth's answer has never completely worked for me. TL;DR : Add set -o vi to your ~/.bashrc .

When using menu-complete in conjunction with vi keybindings, I have to make sure that my ~/.bashrc has:

set -o vi

It's never been enough for my ~/.inputrc just to have:

TAB: menu-complete

set editing-mode vi
set keymap vi

My guess is that somehow set editing-mode and set keymap are clobbering the TAB: ... setting, but I haven't looked into the documentation thoroughly to figure out why this is the case.
