"Source" in bash vs csh

Question

I'd like to understand why sourcing a script in csh works but doesn't in bash. I have files for both csh and bash that set an alias for jr command.

\bsource for bash and \csource for csh

I have two scripts:

source \csource    
jr something

and this works like a charm, but:

source \bsource    
jr something

gives me

jr:command not found

Could someone please shine some light on it as I've searched far and wide to no avail.

Kind regards

BoB

In Bash, aliases are not expanded when the shell is not interactive, unless expand_aliases option is enabled explicitly. Therefore, you should enable this option before sourcing a file with aliases:

shopt -s expand_aliases
source bsource
jr
