Since you're interested in going deeper into terminal customization, tput offers several more advanced text styling capabilities. These are excellent for creating more readable and professional-looking bash scripts.
Here are more tput styles you can explore in your LabEx VM:
1. Formatting Styles (The "Look")
While we've seen bold and underline, there are a few other specific capabilities:
- Dim/Faint:
tput dim; echo "This is subtle text"; tput sgr0- Useful for: Secondary info or timestamps.
- Standout Mode:
tput smso; echo "Standout Mode"; tput rmso- Effect: Usually similar to reversed colors, used to make text pop.
- Blink (Warning):
tput blink; echo "WARNING!"; tput sgr0- Effect: Makes the text flash (Note: some modern terminal emulators disable this for accessibility).
2. Background Colors
You can change the background color of the text using setab (Set ANSI Background):
- Yellow Background:
tput setab 3; echo "Highlighted Background"; tput sgr0 - Blue Background:
tput setab 4; tput setaf 7; echo "White on Blue"; tput sgr0
3. Cursor Visibility
This is useful if you are writing a script and don't want the blinking cursor to distract the user:
- Hide Cursor:
tput civis - Show Cursor:
tput cnorm- Pro-tip: If you hide the cursor, always make sure your script shows it again before exiting!
4. Grouping for Better Readability
Instead of typing tput every time, you can store these in variables. This is a common practice in professional Linux scripting:
# Define styles
GREEN=$(tput setaf 2)
BOLD=$(tput bold)
RESET=$(tput sgr0)
# Use them
echo "${GREEN}${BOLD}Task Completed Successfully!${RESET}"Why this is part of your "Learning Journey":
