 Posted: Sat Sep 27, 2003 1:24 am Post subject: Unexpected bash completion behavior |
 |
|
I recently noticed strange behavior with bash completion. If I use the tab key multiple times on the same command line to complete, on the second or higher time I hit tab the completion does not leave a trailing "/" at the end of the line. I seem to remember that hitting tab would continue to leave trailing slashes if the completion was a directory.
For instance, if I am using tabs to quickly get to /usr/portage/kde-base/kdebase/kdebase-3.2.0_alpha2.ebuild, this is what happens:
| Code: | I type:
/usr/port [tab]
The completion works as expected:
"/usr/portage/"
I then type:
kde-b [tab]
The completion looks like this:
"/usr/portage/kdebase " {note trailing space, no trailing slash}
I expect the completion to look like this:
"/usr/portage/kdebase/"
|
If I keep trying to use [tab] to complete, I keep getting trailing spaces instead of trailing slashes.
This may or may not be related, but I first noticed this after trying to emerge KDE 3.2 alpha packages, but this behavior persists even if I am working in a regular console (no desktop/window manager).

Good spot.
I guess it's a bug in /etc/bash_completion.d/gentoo.
Try this patch: | Code: | --- gentoo.completion-20031225 2003-12-27 11:40:37.000000000 +0000
+++ /etc/bash_completion.d/gentoo 2003-12-31 20:32:26.000000000 +0000

Thanks for the patch -- I'll try it tomorrow. Somehow I missed this thread when it came out.
Regarding my .sig: So I guess that the good news is that a stupid l33t ranking, like most things, shall pass eventually.
The bad news is that I guess I'll have to start hanging out in Off The Wall.
