The code you provided is unable to get the answer when i type in the keyword which existed in the list, it still return 0.
Code:
adm/alvin% [[ -n `grep 'john' list.txt` ]]&& echo `grep 'john' list.txt|cut -d" " -f2`|| echo 0
Missing ]

Program:

$1 can be Marcus or any input you want to find in the file

Code:
grep -c $1 1.txt

if [ $? -ne "0" ]
        then
        echo "0"
fi

Code:
grep 'Marcus' list.txt | awk '{print $2}; END { if (!found) print "0" }'

It returns "0" but it also returns "0" on other names that are not Mary, when you search for Mary. Is that what you wanted?
