Question

I’ve got bash variable

USE_DOTNET="a b c"

I need to go foreach USE_DOTNET and have some case (switch) for each pattern.

alike

foreach x in USE_DOTNET
switch(x)
case a -> do something
case b -> ...

in pseudo code but I don’t know how to implement it in bash?

Answer 1

#!/bin/bash

USE_DOTNET="a b c"

for x in ${USE_DOTNET} ; do
   case ${x} in 
      a) echo "found x="$x ;;
      b) echo "found b"
      c) echo "FOUND c"
      * ) echo "unexpected value found for x=$x" 1>&2
   esac
done

OR, per @jordanm’s comment, you can try

USE_DOTNET=(a b c)
for x in "${USE_DOTNET[@]}" ;do ...

IHTH

(FWIW, your pcode looks close to csh syntax)
