Incorrect execution of `killall` on `plugin-container`

[ill]

When using the `killall` command on the `plugin-container` process, the command does not correctly identify the program and does not terminate the program.

The command `killall plugin-container` will return this:
plugin-container: no process found

When the command `killall plugin-containe`, the process `plugin-container` will correctly be terminated.

ill,
If would please provide some basic info on your version of Ubuntu using the output of 'lsb_release -a' and 'apt-cache policy 'gnome-terminal' it would be appreciated.

I confirmed this behaviour using gnome-terminal, Firefox and a youtube video to provide the plugin-container. Once I had the video open I used gnome terminal to enter 'killall plug +TAB', which did show the tab completion however the command would return 'plugin-container: no process found' until I deleted the last 'r' in 'plugin-container', at which point the command completed successfully.

[Thomas Ward (teward)]

I tested this with Bash and gnome-terminal in 12.04.

This bug exists in Precise, however it exists in all terminal emulators, tty terminals, and is not specific to gnome-terminal, which suggests this is a bug with bash-completion or the source pacakge for killall, psmisc.

Therefore, I am adding that this affects bash-completion, and setting this for gnome-terminal as Opinion, as this can occur in any and all terminal emulators, including remote SSH sessions.

I am also adding this to affecting killall's source package, psmisc, because of the issue that james-plate is having (which I can confirm) that when you do `killall plugin-container` it cannot find the process, but can find the process with `killall plugin-containe`.

ill: in regards to your post, those are apt-get error logs, and do not particularly help this situation. However, since you have confirmed that this is not gnome-terminal specific, the status of 'opinion' is validated.

[Thomas Ward (teward)]

Disregard everything in #6, except that the status of 'opinion' is invalidated. (clicked 'post comment' too early)

[Thomas Ward (teward)]

correction to #7 (auto-complete error in Firefox in my instance): invalidated should be validated

[Thomas Ward (teward)]

Confirmed against 'psmisc' because the bug is reproducible in other shells (tested: bash, zsh) under the same circumstances.

Reconsideration may be needed by other bug squad members for bash-completion bugs, as this bug is reproducible under zsh for `killall`, but tab-completion is not handled for killall in zsh.

Setting Low importance per Thomas Ward on IRC

[Micah Gersten (micahg)]

Removed gnome-terminal and bash-completion tasks per Thomas Ward on IRC (this bug will focus on the issue of not killing the process properly and a new one will be filed for the bash completion issue)
