    <p><strong>Hello all,</strong></p> <p>I trust you're well as you read this request for assistance. I am not very experienced in the Linux world, but all the same I'm striving to learn as quickly as possible. So please pardon any obvious ignorance on my part and assist if possible.</p> <p>I am running a ClearOS v5.2 Enterprise server (based on the Centos linux distro) and I'm using the following command in a shell script to backup my MySQL database.</p> <pre><code>mysqldump -u root -pMYPASSWORD --all-databases &gt; /mnt/shares/flexshares/backup/MySQL/mysql-backup-`date +%Y-%m-%d-%H-%M`.sql </code></pre> <p>I use a cron job to call this script @ 1:15 AM daily. Now, I can see in the cron log that the job is executed at that time and the script is called, but the command doesn't execute (log entries below). I say this because I don't see the sql file being created in the <strong>/mnt/shares/flexshares/backup/MySQL</strong> directory.</p> <pre><code>Aug 21 01:15:01 server1 crond[27842]: (root) CMD (/root/my_scripts/backup-mysql.sh) Aug 22 01:15:01 server1 crond[9031]: (root) CMD (/root/my_scripts/backup-mysql.sh) </code></pre> <p>Strangely enough, if I run the same command from the CLI it executes without any problems and the MySQL database is dumped to the target directory (<strong>/mnt/shares/flexshares/backup/MySQL</strong>).</p> <p>What am I missing or what have I included in the script that's causing it not to run? Here's my shell script (<strong>"backup-mysql.sh"</strong>):</p> <pre><code>#!/bin/bash # FULL BACKUP OF MySQL DATABASE mysqldump -u root -pMYPASSWORD --all-databases &gt; /mnt/shares/flexshares/backup/MySQL/mysql-backup-`date +%Y-%m-%d-%H-%M`.sql </code></pre> <p>I am very grateful for any help I can get, thanks.</p> <p>v/r</p> <p>Kismet</p>

    1. COWhere are you looking for your dumped file ? They supposed to save under /mnt/shares/flexshares/backup/MySQL/mysql-backup-`date +%Y-%m-%d-%H-%M`.sql

    2. COOne possibility(?) Q: Is "/mnt/shares/flexshares/backup" on a local filesystem, are is that on an auto-mounted remote filesystem? If its not local, then maybe that's not available at the time cron runs the script(?). If it were me, I'd verify that and run a test that writes to known filesystem that has write permissions: `/tmp`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
