How to remove Bash under Debian.

Some people were wondering how to say goodbye to bash.
Personal reasons vary from security risks to bloat, or "Just because I can, and I want too."
Only if you are aware of the risks, have decided it is your OS/machine/time anyway, and are hellbent on this action should you continue.

Pardon my asking, but this is helpful how, and to who?

I do not mean to be impolite, but please reconsider this and do not fill LQ with harmful, pointless and useless "how-to's".

I always like these posts.

The Be Operating System was build up from ground up without a shell. Linux can't seem and maybe doesn't really need to get along without a shell.

I just read your howto, and it will probably last until the next time you install or upgrade anything with apt-get.

It's tremendously likely that it will leave a lot of stuff in a nonworking state too.

How are you going to be aware of the risks if you don't even look at the list of files that you're changing?

The howto is intended to replace bash with dash.

Debian already has changed from bash to dash as much as possible.

Ubuntu follows debian.

I think it's a matter of distribution makers. Casual users must not attempt. Else there is chance of not functioning OS.

I sym-linked /bin/sh to /bin/ksh (actually pdksh) years ago. The only thing that broke was ldd, which was easily fixed:

Code:

head -1 /usr/bin/ldd
#! /bin/bash

So it seems that Slackware (or slackware 11.0, at least) can live without bash -- ldd is useful but hardly essential. There are a few other scripts around which explicitly require bash i.e. they have a #!/bin/bash line, but nothing important.

well there is csh and ksh

but almost every "*.sh" script is pointing to "#!/bin/bash " or "#!/bin/sh "
