sed: -e expression#1, char3 : expected newer vesrion of sed.

sed -n '$vp' file

Can you please tell me if i have to print specific line number from the found pattern. Eg, if i have found pattern on line 6 , i need to print next to next line or say third line from the found pattern

Hi sarbjit,
sed -n "$vp" file won't work as shell will search for value of vp variable instead of variable v. Try this.
sed -n "${v}p" file
Also if you have multiple matches of the search string & you need line no of first match try this:
v=`awk '/searchtext/{print NR ; exit}' file`
