UNIX for Beginners Questions & Answers

Hello,

I am using the command below to send emails to users using a for loop. If The command finds the user Id in 1st column then it will print the email Id of the user from the 2nd column.

Code:

/usr/bin/awk -F "," ' $1 == "username"  {print $2}' file.csv

This command is getting executed when I give the username directly or execute it manually in command line. But when I try to use the same code in shell script to process various usernames in a for loop, the awk command doesn't recognize the variables

The code I am using in shell script is below. Can someone please let me know how to fix this?

Code:

For usr in ${users[@]}; do
/usr/bin/awk -F "," ' $1 == "$usr"  {print $2}' file.csv
done > out.txt
