Nice article :)

This article is good one, I found out some new things :)
There is just this one little problem: bash somehow calculates, where to break command line to next line, and counts in ALL the characters, not just the visible ones. So when using this technique, bash will screw up the display, if a long command line is entered.

Any ideas how to prevent it?

Guncha you are right, but for this problem there are the \[ \] tags in the lines.

Very informational. I was looking for a good tutorial on ANSI coloring for a long time. Thank you. A very small error, I discovered though. In your first example, you forgot to close off the tag to make it the default shell color when writing. Thought I'll point it out. Regards.

Nico, i've read your article and noticed that at your last example (the cron startup script) we should use "echo -e" instead of "echo" in order to get scaped commands interpreted correctly.

Hi Cadu,
i use "echo" instead of echo -e and it works correct.

I noted a small error in the text. When the second PS1 is discussed, the result lacks the hostname... \u@\h gives something like "johndoe@linux10".

Hi, there is a project that lets we easily access all text formats and colors on terminals, take a look at http://scriptechocolor.sourceforge.net/ .

Here is mine:

PS1='\[\033[0;34m\][\d]\[\033[0m\]\[\033[1;34m\][\@]\[\033[0m\]\[\033[0;36m\][\u@\h:\[\033[1;36m\]\w\[\033[0m\]\[\033[0;36m\]]\[\033[0m\]\[\033[1;37m\]\$\[\033
[0m\] '

that works only after you log in. i want to change the default setting from gray to white - the bootprocess output should be white as well.
So how can I get it?

ANSWER To Prevent bash from miscalculation of line-length, You just habve to escape the sequence of non-printable characters with \[ and \] before and afterwards.

Yes thank you very much indeed for this really helpful article.I pointed my teenage son to your explanations and he read and appreciated the way you did it.Also he gives you far more "authority" on the subject as you are in the same generation (I suppose) as he.!!We had some fun also making humorous prompts etc for ourselves and family and friends.Many thanks again from two New Zealand BASH-lovers.

Thats Nice!

Is it possible to do the color change in a php shell script? If so, how?
