@Martijn
Are you setting up the cron job yourself, or using a hosting provider?

The error simply means it can’t find the script on the path, $HOME/scripts/daily_sql_backup.sh

There are a few possible causes:
1) That’s not where you saved the script (try pasting that command directly in the command line, with the full path)
2) The $HOME variable is not set (replace with full /home/myUserName)
3) Your host uses a different user to run the cron jobs, and $HOME is invalid (replace with full /home/myUserName)

Thanks! That is a handy trick to backup multiple databases on the same host.

Since I use a few hosts I may tweak that script above to use one master password for each host, and then run through all contained databases. Easy change by wrapping your loop inside a larger loop based on hostnames.
Fantastic!

This script has served me well for the last year or more, but when I mentioned that new databases need to be added by hand a learned friend suggested the following:
for db in $(mysql -e "show databases" -B --skip-column-names); do mysqldump --opt --databases $db | gzip -3 --rsyncable > /var/backups/$db.sql.gz done
of course you may need to append your host, user & password credentials, depending on your environment.

hi i made a shell script to dump mysql select result to csv file
the script works very well when i run it manual,but the crontab doesnt run,
it is just creating the empty csv file
below is the file

#!/bin/bash
datetime=`date +”%Y%m%d”`
FILE=”/tmp/mysql_dump/mydumpfile_$datetime.csv”
mysql -uuser -pmypasswor db1 -e “select subtoken MSISDN,state,expiration_date from comp_subscription,comp_subscription_information
where comp_subscription.id=comp_subscription_information.comp_subscription_id
order by expiration_date” > $FILE

Please advise
Regards

@Tony
Did you add the script specification at the start of the file
#! /bin/bash
and mark it executable?
chmod 0755 daily_sql_backup.sh

Hi,

thanks for the post, I get:

/bin/sh: /var/www/vhosts/troid.org/httpdocs/backups/daily_sql_backup.sh: cannot execute binary file

So it seems the cron command is executing (had to delete the log part first) but it can’t run the file, I’m on Plesk if that means anything.

Appreciate your efforts!

Tony
