/bin/zsh for shell language

[OliverJAsh]

I see /bin/bash as a language for shell scripts, but I don't see /bin/zsh. Is there any reason for this? zsh is quite popular…

Is zsh installed by default on OS X? If not, that'd be why.

But you can always launch into another shell environment from within bash though, right?

[OliverJAsh]

You're right - you can launch it from within bash.

 

I believe it is shipped with OS X.

 

If I launch /bin/zsh from within bash, will it execute my zshrc, do you know? It's not finding any of the command-line utilities in my bins.

I believe Andrew has said that none of the user-specific environment settings are loaded when shell scripts run. This is to make them able to be transferred freely to other users without compatibility issues. You just have to make sure you call the full path rather than any aliases you have set up. For example, in my own (bash) scripts, I can't just use "growlnotify" like I normally would, I have to put the whole "/usr/local/bin/growlnotify" into my scripts. Personally, if it's a command I'm going to be using a lot, I just manually add an alias at the top of the script. Or just do a find-replace when you're done. )

Perfect answer. Cheers!

Strangely, when I alias, I cannot execute the binary:

 

 

 

#!/bin/zsh


alias audiodevice="/Users/Oliver/.bin/audiodevice"


audiodevice

This doesn't work. Nothing is echoed, thus the `audiodevice` binary is not running.

 

If I do this, however, it works:

 

 

 

#!/bin/zsh


/Users/Oliver/.bin/audiodevice

I don't know if it's the same for zsh, but for bash I discovered (thank you Google) that aliases aren't loaded by default when running scripts.

 

I had to add this to the top of my scripts:

 

 

#Enable aliases for this script
shopt -s expand_aliases

 

 

 

which did the trick.

 

Hope that helps.
