What kind of undurline do you want ?

For printing ? TEXT\b\b\b\b____
For displaying on screen ? \033[4mTEXT\033[0m
Other type ?

Try..
[tt]
STRING='search text'
FILENAME='yourfile.txt'
SU=`tput smul`
EU=`tput rmul`
sed -n "s/\($STRING\)/$SU\1$EU/p" $FILENAME

Solution 1 using sed :
[tt]
--- underline.sh ---
[ $# -eq 0 ] && exit
SedFile=/tmp/underline.sed.$$
Text="$1"
shift

cat <<EOF >$SedFile
s/\($Text\)/$(tput sgr 0 1)\1$(tput sgr 0 0)/g
EOF

sed -f $SedFile $*
rm -f $SedFile
--------------------

underline.sh searched_text [ files... ]
[/tt][/i]

Solution 2 using awk :
[tt]
--- underline.awk ---
BEGIN {
if (ARGC < 2) exit;
&quot;tput sgr 0 1&quot; | getline Under_On ;
&quot;tput sgr 0 0&quot; | getline Under_Off ;
Text = ARGV[1] ;
ARGV[1] = &quot;&quot;;
if (ARGC == 2) ARGV[ARGC++] = &quot;-&quot;;
Underlined = Under_On Text Under_Off;
}
{
gsub(Text,Underlined);
print $0;
}

---------------------

awk -f underline.awk searched_text [ files... ]
[/tt]

Try something like this:

smul=`tput smul`; sgr0=`tput sgr0`
str="YourSearchedString"
awk '{gsub(/'"$str"'/,"'"${smul}${str}${sgr0}"'");print
}' /path/to/file
