I'm trying to echo the error message as well as writing it in a log file at the same time but I'm not sure how to do it. I've used 1>&2, but it just sends it to the log file and doesn't echo the message. Here's my code:
while read -r username password; do
egrep "^$username" /etc/passwd >/dev/null
if [ $? -eq 0 ]; then
echo "ERROR BLABLAH $DATE" 1>&2 >> /var/log/error.log
echo "ERROR BLABLAH $DATE" | tee -a /var/log/error.log 1>&2
tee # will repeat the std input. -a /var/log/error.log # will append to the error.log file 1>&2 # will send the stdin to stderr.
