boolean type for while loop in bash?
- by user151841
I have a cron script on a shared web host that occasionally gets killed. I'd like to make a loop in bash that tries again if it gets killed, because most of the time it will make it. I'm having trouble with the syntax for storing a boolean value :P
#!/bin/bash
VAR=0;
while [ $VAR ]; do
if nice -19 mysqldump -uuser -ppassword -h database.hostname.com --skip-opt --all --complete-insert --add-drop-table database_name > ~/file/system/path/filename.sql; then
VAR=1;
fi
done
So the script recovers from a killed process okay, but once it's run properly, the new VAR value doesn't kill the while loop.
What am I doing wrong?
