file extension renaming (bash to csh)?

[tuathan]

How do i write this bash script that changes file extension from .abc to .def in csh:

> $ ls
> test1.abc test2.abc test3.abc test4.abc
>
>
> $ for i in *.abc; do
> > mv "$i" "${i%.abc}.def" ;
> > done
>
> $ ls
> test1.def test2.def test3.def test4.def

>ls
test1.abc test2.abc test3.abc

>foreach n ( `ls *.abc` )
foreach? set base = `basename $n .abc`
foreach? mv $n $base.def
foreach? end

>ls
test1.def test2.def test3.def

>echo $shell
/bin/csh

there's also a built in csh command "rename"!


>ls
test1.abc test2.abc test3.abc

>rename abc def *.abc

>ls
test1.def test2.def test3.def
