Greetings
I'm trying to get as close to a switch statement in hush shell language
as possible and thought that a set of if/then/elif/else would be tidier
than nested if/then/else. It doesn't work how I expected however. The
example below illustrates the problem - I was expecting execution after
a true test (in the first 'if' in this case) to continue after the 'fi'
but instead it ploughs through all the other executable (echo)
statements having skipped the elif statements. It does correctly skip
the else clause however :-))
Could someone assist in the navigation of this module to point out where
would be a good place to start (i.e. some basic principles and
assumptions of how the parser works).
[apologies for the word wrapping]
=>if iml; then echo "one"; elif iml; then echo "two"; elif iml; then
echo "three"; else echo "four"; fi
