Pankaj,
See if this would work for you:

Code:

BU=`tput smul`
EU=`tput rmul`
echo "${BU}All underline${EU}"

It may be dependent on termcap/terminfo.

The command is any command that sends the correct escape sequence to the screen. The sequence doesn't change.

Shell:

Code:

printf "\e[4m%s\e[0m\n" TESTING

AWK:

Code:

printf "\e[4m%s\e[0m\n", "TESTING"

If your terminal isn't standard, it may not support underlining, or may require a different sequence. These days, such terminals are rare, but you may be able to get the sequence with tput.. Read the man pages for tput and terminfo and/or termcap.
