Question

I have the following in a file which is sourced both by .bashrc and .zshrc. The syntax is from the site.

if $SHELL=/bin/zsh                                                               
         then
     # to not java .class when running java 
             myclasslist () { reply=(${$(ls *.class)%.class}) }
             compctl -K myclasslist java
fi

Both Zsh and Bash go upset of it.

How can you make a if -clause in sh?

Answer 1

You need to wrap your condition in the test operator (as well as quotes to get in the habit):

In shell:

#!/bin/sh
if [ "$SHELL" = "/bin/zsh" ]; then
       # do your thing
fi

In bash:

#!/bin/bash
if [ "$SHELL" == "/bin/zsh" ]; then
    # just do it!
fi
