Well, I think the problem is with your read keys from the keyboard

When you run the script, make sure that you enter the text when prompted. I dont see any other reason why it wouldn't work. Good luck

Code:
#!/bin/bash 

read -p "first name:" nme 
awk -F":" '/$nme/{print $1}' listfile.txt > otherfile
file1="${nme}"
if grep -q "$file1" otherfile 
then 
echo "$file1"| sed -i "s/two:$(date '+%Y%m%d')/one:::/" 
else 
echo "it is out" 
fi

now format of listfile is
firstname:lastname:two:date:

I want this to be change to:
firstname:lastname: one

can someone check problem in this script?

Few questions for you:
1. What is the o/p you are getting now?
2. when you say "date", do you literally mean the string "date" or the actual date as in time.
3. Can you tell what is that you want to achieve?

It would be just easier, if you give us the input file content and the expected output.

1. It is giving else option all the time " it is out"
2. it is not string, it is actual date
3. firstname: lastname: two: date:
this is already in file
and i want to change it to
firstname:lastname: one::

Take $nme instead of $title

As I mentioned, it will be easier for us to solve the problem, the need of the script rather than trying to fix a script without not the real background.

May be you can try something like this


Code:
#!/bin/bash

read -p "first name:" nme
echo $nme
awk -F":" -v nme=$nme '$0 ~ nme{print $1}' listfile.txt > otherfile
file1="${nme}"
if grep -q "$file1" otherfile
then
sed "s/two:$(date '+%Y%m%d')/one:::/" listfile.txt
else
echo "it is out"
fi
