Here's how:

echo -e "text \033[1mbold\033[0m text"

See "Colorizing" Scripts tutorial.

It's not possible to do for cat that way. cat will merely print the characters of the file onto standard out. The closest thing I can come up with is the following:

If you put text \033[1mbold\033[0m text you can do

echo -e `cat test.txt`

what I wanted in cat is the same. I do 'echo -e "text \033[1mbold\033[0m text" > myfile' and then 'cat myfile' thank you for showing this. –  varsketiz May 26 '11 at 9:07

More generally, "echo $(tput bold)" and "echo $(tput sgr0)" will work for any terminal, not just ANSI/VTxxx-compatible ones. –  njd May 26 '11 at 10:28
    
@njd, ah, good point. –  aioobe May 26 '11 at 10:31
