Code:
while IFS='|' read f1 f2 rest; do
    echo "$f1|${f2%%.*}|$rest"
done < $1

Code:
prog.sh dataset.txt > saved_result.txt

Once that saved_result.txt is what you want, you can rename it.

check-hostname(1M)					  System Administration Commands					check-hostname(1M)

NAME
check-hostname - check if sendmail can determine the system's fully-qualified host name SYNOPSIS
/usr/sbin/check-hostname DESCRIPTION
The check-hostname script is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name (FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports success. Other- wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined. FILES
/etc/hosts Host name database /etc/nsswitch.conf Name service switch configuration file /etc/resolv.conf Configuration file for name server routines ATTRIBUTES
