The coloured messages on the screen.
The following shows that the bash is on my system.
[ka@c83-250-94-177 ka]$ cat /etc/shells
/bin/bash
/bin/csh
/bin/sh
/bin/tcsh
[ka@c83-250-94-177 ka]$
-----------------------------------------------------------------------------------------
The following echo command prints message in Blue color on console. I found this on a website.
$ echo -e "\033[34m Hello Colorful World!"
Hello Colorful World!
-------------------------------------------------------------------------------------------------------------------
However, it didn't work the way it should work. Please read the following:
[ka@c83-250-94-177 ka]$ echo -e "\033[34m Hello Colorful World!"
bash: !": event not found
[ka@c83-250-94-177 ka]$
What is the problem?
