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 convers=
e
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 whol=
e
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 t=
he
two. Typically you'ld have to know both languages and laboriously transl=
ate
between them.
Cheers,
Matthew
