grep error on login, related to alias-completion

[daniejstriata]

On some of the installs I get an error when I login the first time:

Usage: grep [OPTION]... PATTERN [FILE]...

I'm not able to replicate this or figure out why the grep error happens as it is not on all the hosts but when I disable alias-completion the error goes away.

Steps to Reproduce

1. Login to server
2. Grep error will be the last entry seen before the prompt.

@daniejstriata, pls try to disable the alias-completion plug-in and enable the aliases completion. Does that remove the error?

I've just noticed this report is from a checkout from November, so you don't have an aliases completion. I would recommend disabling that version of the aliases-completion plug-in: It runs all defined aliases in an eval at every load.

[daniejstriata]

I'll delete and check it out again.

FYI

I got this error after disabling and enabling the plugin

-bash: /tmp/alias_completion-26879C0G9go: line 1: syntax error near unexpected token `cd'
-bash: /tmp/alias_completion-26879C0G9go: line 1: `cd - '

I deleted the .bash_it directory and checkedout a new version. This time around the alias completion plugin was not found when I logged in:

aliases enabled with priority 800.
alias-completion disabled.
-bash: /root/.bash_it/completion/aliases.completion.bash: No such file or directory

[John D Pell]

@daniejstriata, sorry, that last is a typo fixed in #2089 and you should only get that not-found error the first time it loads. Do you still get the syntax errors?

Aside: you can just run bash-it update to get the new checkout. 👍

[daniejstriata]

It is like you said. The first time give that error. now the second time now longer give syntax error near unexpected tokencd'` error.

Now everytime this happens:

Once I logged in again and get the error:
-bash: /root/.bash_it/completion/aliases.completion.bash: No such file or directory
I log out and log back in again. Then the plugin no longer shows that it is active

[John D Pell]

Pls disable the plugin alias-completion and enable the completion aliases. The error is fixed in #2089, which was just merged.

[daniejstriata]

Thanks. I got this message when I logged in

aliases is already enabled.
alias-completion disabled.

I do not see aliases under plugins to enable/disable it. The only plugin enabled is base.

[John D Pell]

Now that #2089 is merged, you shouldn't see any of that again. The alias-completion plugin should be disabled automatically, and the aliases completion should be enabled automatically. Note that aliases is a completion, not a plugin. It should have priority 800. You can see it enabled as $BASH_IT/enabled/800---aliases.completion.bash.

[daniejstriata]

Thanks! Makes sense. All good.
