Shell Programming and Scripting

I would like to "BOLD" print the hostname in the following statement:

export PS1=$USER"@"$(hostname -s):'$PWD>'

Is there a special character I can put before and after the variable to make it bold or blinking?

Thanks.

Code:

export PS1='\u@\033[1m`hostname`\033[0m:\w> '
or
export PS1='\u@\033[1m\h\033[0m:\w> '

That's pretty much the copy+paste answer, but it's in bash syntax, which may or may not work for you.

In general, ANSI codes starting with esc [ and ending with m after some numbers work well, but they're not portable to all terminals. A (slightly) more portable solution would be to use tput

Code:

PS1=$USER"@"$(tput bold)$(hostname -s)$(tput sgr0):'$PWD>'

See the tput manual page for more information.

Perhaps you will find that the codes output by tput are exactly equivalent to the hard-coded escape codes given above. In theory, tput should be portable to terminals which do not speak ANSI, but I don't know of a real-world situation where this would make an enormous difference.

(The code \033 is octal for the escape character.)

cheers, drl

tput method worked for me, thank you all for your generous input.
