Bug 305257 – bash-completion ssh -bash: _known_hosts_real: command not found

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Krzysiek Bielicki 2010-02-15 14:21:01 UTC]

Bash completion for ssh in not working.
After installing app-shells/bash-completion and eselect bashcomp enable ssh, ssh <tab> prints "-bash: _known_hosts_real: command not found" instead of printing known hosts suggestions.

Run `. /etc/profile.d/bash-completion.sh` or launch a new shell.

[Comment 2 Krzysiek Bielicki 2010-02-16 12:30:03 UTC]

Generally bash completion is working (ex. for emerge) so bash-completion is initialized.

_known_hosts_real is called only from bash_completion.d/ssh so bashcomp scripts are executed as they should, but _known_hosts_real function/executable does not exist.

I can confirm that bashcomp is generally working, but the the issue with ssh host completion

Well, it works perfectly fine here w/ app-shells/bash-completion-1.1-r5:

$ ssh <TAB><TAB>
::1          alfa         gw           localhost    notorcomp    printserver  

_known_hosts_real exists in /etc/bash_completion.d/base

I've been having this problem for some time. Enabling the `base' bash_completion module brings in the _known_hosts_real function (and the /etc/bash_completion.d/base file), which fixed it for me.

Try the following,
`eselect bashcomp enable --global base'

[Comment 6 Nick Loeve 2010-02-22 10:18:55 UTC]

Yep, enabling base fixes the issue!

[Comment 7 Jeremy Olexa (darkside) (RETIRED) 2010-02-27 21:10:44 UTC]

almost everything needs base, glad you resolved the issue

[Comment 8 Adrian 2010-10-13 11:57:13 UTC]

This is not a good solution. Enabling 'base' causes e.g. ~username completion to fail in lots of cases, e.g. tab-completing the username in 'cd ~someuser'

cd ~userna<tab> completes to /home/username/

[Comment 10 Adrian 2010-10-13 13:21:55 UTC]

As soon as I enable the 'base' bashcomp it stops working.
