'for {variable_name}' can replace foreach in Bourne Shell.
If you can provide more information, like what you're doing with the
shell script, please let us know.
I'm a big fan of Perl, in particular in cases where text parsing
doesn't cut it in Bourne shell / with the simple utilities (i.e. cut(1),
sed(1), etc), but in an effort to try and avoid having Perl installed on
every single machine, I provided the previous Bourne shell example.
