Exactly the same in posix standard /bin/sh or in bash. bash(1) should
be capable of running any compliant /bin/sh script directly. The converse
is not generally true, so for maximum portability write according to sh(1)
and avoid bash-isms.
If you're asking about converting csh to bourne shell, then that's a whole
other kettle of fish. The echo commands above just happen to be the same in
either language, but that's one of the few points of confluence between the
two. Typically you'ld have to know both languages and laboriously translate
between them.
Cheers,
Matthew
