Having a colourful display on shell script is something that’d beautify your experience. Using colour text and echos will help you to highlight and distinguish the shell output on a linux prompt.<\/p>\n\n\n\n

Here’s how you can have colored text in linux shell, try following command on your bash:<\/p>\n\n\n\n

bash $] tput setaf 1
You will see your text color will turn red.
To reset it you can type following command to make text color white
 bash $] tput setaf 7<\/span><\/code><\/pre>\n\n\n\n
or to reset everything again text modes
 bash $] tput sgr0<\/span><\/code><\/pre>\n\n\n\n
Same things you can use in your bash script to colorize output.<\/p>\n\n\n\n
Create following sample bash script for colourize echo:<\/p>\n\n\n\n
# vi try.sh <\/em>\n#ColourfulText<\/em>\ntxtrst=$(tput sgr0) # Text reset<\/em>\ntxtred=$(tput setaf 1) # Red<\/em>\necho \"Welcome to ${txtred} kedar.nitty-witty.com ${txtrst}!\"<\/em><\/code><\/pre>\n\n\n\n
The coloured text output is as follows::<\/span><\/span><\/em><\/span><\/p>\n\n\n
\n
\"colored-shell-script\"<\/a><\/figure>\n<\/div>\n\n\n
If you need more colors, you may define them as follows in shell script:<\/p>\n\n\n\n
Other variables you can define as follows:<\/p>\n\n\n\n
txtgrn=$(tput setaf 2) # Green\ntxtylw=$(tput setaf 3) # Yellow\ntxtblu=$(tput setaf 4) # Blue\ntxtpur=$(tput setaf 5) # Purple\ntxtcyn=$(tput setaf 6) # Cyan\ntxtwht=$(tput setaf 7) # White\ntxtrst=$(tput sgr0) # Text reset.<\/code><\/pre>\n\n\n\n
Following are the tput details further:<\/strong>
tput setab [1-7] : Set a background colour using ANSI escape
tput setb [1-7] : Set a background colour
tput setaf [1-7] : Set a foreground colour using ANSI escape
tput setf [1-7] : Set a foreground colour<\/p>\n\n\n\n
tput Text Mode Capabilities:<\/strong><\/p>\n\n\n\n
tput bold : Set bold mode
tput dim : turn on half-bright mode
tput smul : begin underline mode
tput rmul : exit underline mode
tput rev : Turn on reverse mode
tput smso : Enter standout mode (bold on rxvt)
tput rmso : Exit standout mode
tput sgr0 : Turn off all attributes (doesn’t work quite as expected)
