bash scripts

Explains: echo Command (echo $”string”) Double-quoted String Preceded By a Dollar Sign

by on October 22, 2010 · 2 comments

I noticed that many shell scripts in /etc/init.d/ directory use the following syntax:

echo $“Usage $prog start|stop|reload|restart”

Why a double-quoted string preceded by a dollar sign ($”string”) using the echo command under Linux / UNIX bash scripts?
