    <p>I have a simple php page that writes a file to my server.</p> <pre><code>// open new file $filename = "$name.txt"; $fh = fopen($filename, "w"); fwrite($fh, "$name".";"."$abbreviation".";"."$uid".";"); fclose($fh); </code></pre> <p>I then have a cron job that I know runs as root as test that and need that.</p> <pre><code>if [[ $EUID -ne 0 ]]; then echo "This script must be run as root" 1&gt;&amp;2 exit 1 fi </code></pre> <p>The cronjob is a bash script that can detect the file exists, but it can't seem to read the contents of the file.</p> <pre><code>#!/bin/bash ###################################################### #### Loop through the files and generate coincode #### ###################################################### for file in /home/test/customcoincode/queue/* do echo $file chmod 777 $file echo "read file" while read -r coinfile; do echo $coinfile echo "Assign variables from file" ############################################# #### Set the variables to from the file ##### ############################################# coinName=$(echo $coinfile | cut -f1 -d\;) coinNameAbreviation=$(echo $coinfile | cut -f2 -d\;) UId=$(echo $coinfile | cut -f3 -d\;) done &lt; $file echo "`date +%H:%M:%S` - $coinName : Your Kryptocoin is being compiled!" echo $file echo "copy $coinName file to generated directory" cp -b $file /home/test/customcoincode/generatedCoins/$coinName.txt echo "`date +%H:%M:%S` : Delete queue file" # rm -f $file done </code></pre> <p><code>echo $file</code> recognises the file exists</p> <p><code>echo $coinfile</code> is blank</p> <p>Yet when I <code>nano ./coinfile.txt</code> in terminal I can see clearly there is text in there</p> <p>I run <code>ls -l</code> and I see that the file has the permissions</p> <pre><code>-rw-r--r-- 1 www-data www-data </code></pre> <p>I was under the impression that this would still mean the file can be read by other users? Do I need to be able to execute the file if i am opening it and reading the contents?</p> <p>Any advice would be greatly appreciated. I can expand and show my code if you want, but it was working before when I called a bash script to write the file... and that time it would save the file under root user with rwx for most and then could be read. But this then caused other issues in the php page, so is not an option.</p>

    2. COI didn't downvote, but you're going to need to post more information for people to be able to help you. As it is this question is unanswerable. Please post the contents of your bash script, the crontab, the full path to the file, and the *exact* error you get.

    3. COHey thank you for the constructive comments :) I have added code in to show the basics of what is going on. There is no error message, simply that the file is being read as being empty. full path /home/test/customcoincode/queue/coinfile.txt

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
