That depends on what you want 'echo "raghu\tkumar"' to display. I'm assuming
that you want it to output a tab. If so, why not just embed a tab in the
string? That avoids having to modify echo on every Linux box you'll ever want
to run the script on.
Or you could implement a run-time test:
if uname | grep -i linux >/dev/null 2>&1; then
ECHO="echo -e";
else
ECHO="echo";
fi
and then use $ECHO in all places.
