How to easily add colored text output in bash scripts
Here is small snippet that can give your shell scripts some nice output: colortext.sh As with the debug.sh script, just download it to the same directory as your own script and add it with
1 |
. colortext.sh
|
It contains one simple function called text with the syntax text “text to be output”. Color can be red, green, yellow, blue or grey. The function does not automatically add a linebreak to the putput, so pop a \n in there if you need it. I prefer using it together with printf for clean and easy color output.
Here are some examples of how the function can be used, and below the corresponding output:

. colortext.sh
echo "normal text"
text blue "blue text, "
text yellow "yellow text\n"
# Using it together with echo
echo -n "Status of script: [";text red "ERROR";echo "]"
# more elegant usage with printf
printf "Status of script: [%s]\n" $(text green "OK")

Output:
normal text
blue text, yellow text
Status of script: [ERROR]
Status of script: [OK]
