ksh vs bash

Both are POSIX compliant. So they have a LOT of common function. This is expected.

When you look at "features" - meaning something like the _ variable in ksh and substring ${str:2:2} paramter substitution in bash then you see differences. Neither one of these is a standard shell feature.

External commands, /usr/bin[somecommandname], have nothing to do with shells. They live in their own world.

Hi, pasricha.kunal

Welcome to the forum..

See these links as well as others you find with a Google search:
Comparison of command shells - Wikipedia, the free encyclopedia

somewhat obsolete, but occasionally useful:
UNIX shell differences and how to change your shell (Monthly Posting)

and a more general comparison of scripting languages:
Rosetta Stone for Scripting Languages

Best wishes ... cheers, drl
