Hi,

One way to do this would be to take the output of your awk command, and directly use that via command substitution as input for the date command to work on.

In the following example, we have a file containing UNIX timestamps. We want to convert those timestamps to human-readable dates. So we read in each line of the file, get our timestamp, and pass it to the date command.

Code:
$ cat date.txt
Timestamp 1561734809
Timestamp 1561734820
Timestamp 1561734842
$ cat timestamp.sh
#!/bin/bash
for timestamp in `/bin/cat date.txt | /usr/bin/awk '{print $2}'`
do
        /usr/bin/date -d @"$timestamp"
done

$ ./timestamp.sh

$

Note that this example assumes you are using Bash as your shell - if you're using something different, then please provide full information on the nature of your environment.

Hope this helps !
