De-bashing DebianDe-bashing DebianPosted May 27, 2010 13:54 UTC (Thu) by Tobu (subscriber, #24111)Parent article: De-bashing Debian Many bashisms tend to improve maintainability. For example, [[ ]] helps prevent quoting errors, and >() is more foolproof than creating temporary files or fifos. I don't see a big performance impact in supporting some of these extensions in an extended mode for dash, to get a bit more speed than bash without doing a lot of pointless porting.

And with systemd [see recent LWN article], eventually there is less need to use shell for booting.

Hopefully not -- bash syntax makes for perfectly readable conf files. One of my biggest annoyances with upstart is that Scott invented yet another poorly documented config file syntax instead of just embedding bash and using it for all his config needs.

the usage of globs on the RHS of tests makes life a lot nicer too
POSIX: case ${foo} in *"simple string"*) bar=true;; *) bar=false;; esac

By all means, use bash in your scripts... just don't lie to the computer by telling it the script is written in sh.

this article is about moving from bash to POSIX shell, not about bashisms showing up in scripts using /bin/sh as their interpreter

In that case I have completely misunderstood this article, as I read it as being entirely about bashisms showing up in scripts using /bin/sh as their interpreter.

The correct thing to do if you have a good reason to use a bash-specific feature in your shell script is to put #!/bin/bash at the top of it.
