Ok, can you show me a snippet of the contents of the file.

Apprarently, grep is not able to find the string in the file and hence your "else" part of the program is only executed.

to make sure , do a
Code:
echo $file1

and see the o/p of it is there indeed in the file "listfile"

do you want to see how my file look like?

if yes this is the format of data stored in the file

Code:
jo:adam:one::
joseph ul: fernendez:one::



and so on

Can you show me the o/p of this script below:

Code:
#!/bin/bash 
read -p "one name:" nme 
read -p "second name" sn 
file1="${nme}:${sn}:one::" 
echo $file1
grep "$file1" listfile
if grep -q "$file1" listfile 
then 
echo "$file1"| sed "s/one::/two:$(date '+%Y%m%d'):/" 
else 
echo "The book is checked out" 
fi
