Get Colored Man Pages Using Less Command
There is another way to get colored man pages and you can use the less command that is a free, open-source file pager. and you can use this command to view the file contents on screen from top to buttom.
You just need to append the following line into the .bashrc file which is a hidden file located in your home directory which gets read each time a new bash instance launched. and the new bash shell will read all the commands found in this file and executes them.
export LESS_TERMCAP_mb=$'\E[1;31m' # begin bold export LESS_TERMCAP_md=$'\E[1;36m' # begin blink export LESS_TERMCAP_me=$'\E[0m' # reset bold/blink export LESS_TERMCAP_so=$'\E[01;44;33m' # begin reverse video export LESS_TERMCAP_se=$'\E[0m' # reset reverse video export LESS_TERMCAP_us=$'\E[1;32m' # begin underline export LESS_TERMCAP_ue=$'\E[0m' # reset underline export GROFF_NO_SGR=1 # for konsole and gnome-terminal
Then you need to run source command to make the newly variable to take effect.
$ source .bashrc
Trying to run one man command to check if you get the colored man page:
# man ls
