Hi,
Please help me out on this

I have to store some distribution lists(dl) in a file say mail.txt
Say the file format be
d1 = alok@yahoo.co.in;alvin@rediffmail.com;vijay@yahoo.com; & so on...
d2 = abhinav@gmail.com;dalpit@hotmail.com;garima@yahoo.com;& so on...
d3 = ....
& so on
Now what i want is-->if i pass a keyword say d2 in shell script then it should return me all the id's corrosponding to d2.

Can anybody lemme know how that can be done using shell script?

findKey.sh d1

findkey.sh:

Code:

#!/bin/ksh

key="${1}"

file='mail.txt'

while read currentKey eq addr
do
 [ "${currentKey}" = "${key}" ] && echo "[${addr}]"
done < "${file}"

or with awk:

Code:

nawk -v key=d1 -v FS=" *= *" '$1 == key {print $2}' mail.txt
