Alias exists from removed app

jchambers · 11-10-2007, 11:47 AM

Hello --

I am trying to get rid of the alias.

I did:

apt-get remove ffmpeg
dpkg -r ffmpeg
dpkg --purge ffmpep

But I still get:

# ffmpeg
-bash: /usr/local/bin/ffmpeg: No such file or directory

I tried to find it with grep but I was not successful.

Is there a way to remove this?

Thank you

Start a new shell and see if you get the same thing there. If you do, verify if "ffmpeg" is an alias (do this in the newly-started shell):

Code:

type ffmpeg

What does that command output?

It's gone.

I did not know that... so is caches it for that session?

One more question...

So I installed ffmpeg from source at first then removed it and used apt-get. Would that cached alias/path corrupt an isntall that used ffmpeg? Because I kept getting errors.

I am going to reboot and try again.

Thank you for the help.

AFAIK it shouldn't cause a problem with the package manager. I've never heard of anything like that, and I don't think it is the case. I think you must have encountered some other problem.

Ok thank you.

I have tried so many variations that I may have done some damage at this point... going to reinstall and try that.

Perhaps you ran ffmpeg on the terminal you removed ffmpeg. That terminal still remembers ffmpeg. If you open a new terminal, it will be gone. You can try this: (i) create /usr/local/bin/aaa which contains

Quote:

#!/bin/sh
ls

(ii) chmod +x /usr/local/bin/aaa, (iii) run aaa, (iv) rm /usr/local/bin/aaa, (v) run aaa again. See if you get the same error message. There should be a simple command to clear this "cache" but I don't know what it is.

It was cached..?
I opened a new ssh session and it was gone.
Anyway thank you for the tips.
I had corrupted my system with too many experiments and had to reinstall.
I guess if it's painful you remember not to do that again..
