Top Forums Shell Programming and Scripting Trying to email text, getting blank email Post 302575993 by Corona688 on Wednesday 23rd of November 2011 10:47:40 AM

Code:
for EACH in `cat serverlist.txt`
do
ssh $EACH zoneadm list -ipc | grep running | grep -v "global" >> installed_zones.txt
done

Useless use of cat, dangerous use of backticks. You don't need to run grep 18,000 times for 9,000 hosts either. This would be faster and more reliable:

Code:
while read EACH
do
        ssh "$EACH" zoneadm list -ipc
done < serverlist.txt | grep running | grep -v "global" > installed_zones.txt

Code:
cat /home/galanteb/stuff/installed_zones.txt | mail xxx@xxx.com

Another useless use of cat, though probably not as big a deal. Redirect in a file with < instead. Also, as vbe says, try giving it a subject.

Code:
mail xxx@xxx.com -s "subject" < /home/galanteb/stuff/installed_zones.txt
