 |
|
Hi
Normal completion of bash-commands and filenames seems to work but combined with sudo it does not. If I have a file in the current directory which matches a command then the filename will be used. Example: I have a file 'emerge-log.txt' and when I want to run 'sudo emerge ....' the result is 'sudo emerge-log.txt'. What module must be activated? I have an other machine where it works, but I cannot find the difference.

eselect bashomp list
|
Doesn't show me a sudo module, which to me makes sense. Until sudo runs, how would bashcomp know which commands you would have access to...
What I mean is, a normal or restricted user doesn't have access to all commands, or necessarily even permission to view directories that contain commands. So bashcomp wouldn't list those anyway, with sudo in the mix it would have to run and access the sudoers list before bashcomp could do it's thing. Therefore, rightfully:
would only expand to files in the current directory. |

| The user is in the portage group so 'emerge -p stuff' works with completion of the command. It should work with sudo too. It works on one machine and not the other so it must be some kind of missing setup. |

su
yoursecretpassword
auto-complete to your hearts desire
exit?
Just because sudo is mostly used for running as root doesn't mean that it can't be used to run as other users. If sudo were to concatenate all of the possible users PATHs just for the convenience of auto-completion by any user capable of executing sudo, I wouldn't like it at all.
edit: I must not have been taking my meds when I wrote this.

To use auto completion with sudo You must add to your .bashrc
I have same thing set to man
I think it is what You mean. |

For sudo you need to enable the base eselect bashcomp module:
| Code: | | eselect bashcomp enable base |
