Why do they always focus on bash (or mysql, or php, or whatever).
90% of the article is applicable for other shells, like zsh or fish.
Why not write "how to debug shell scripts"?
- scott_s 17y agoI almost exclusively use bash. Not because of a particular love of bash, but just because that's the default install on Linux (and even OSX). Consequently, I don't know what the real differences are between bash and other shells. It's possible the author is like me: because he's not familiar with what the differences between the shells are, he can't say what does and does not apply to other shells.
- blasdel 17y agoThe differences: * zsh has a ton of interactive chrome built-in, and a lot of it is on by default. This leads to some incompatibility with bash for scripting purposes the contextual completion stuff is infuriating when it's overly restrictive * A pure bourne shell (like dash) by nature doesn't support bashisms like $() as an alternative to `` On almost all gnu systems /bin/sh is a link to bash which checks $0 and operates in sh mode Unfortunately bash's sh mode is completely broken it allows most bash-specific syntax so almost a lot of Linux users's #!/bin/sh scripts really need bash The takeaway is that you should give up and use bash, or write your own shell if you're an asshole (I have done this).
