WRONG!! This is just another one of these
religious statements that confuse many newcomers.
You write in whatever shell language you need to
do the job, using *ALL* the features that make the
task easy to write and maintain.
What if you are using csh...? Are you still
supposed to make it compatible with sh...? Bash is
no different than awk, perl, sed, csh, python
which are all scripting languages.
If you are a software developer that *Needs* to be
compatible with many different Unix systems, then
it would be a good idea, but *Not* absolutely
necessary.
For localized tasks you should use *All* the
features of the shell of your choice and don't
listen to the religious crap.
