This is a great idea! ^_^ thanks for sharing Rene

what is this ". ${MYPATH}/joomlafunctions" ?

Hi Javier, In order for this script to work, you need to install the script joomlafunctions as well" https://gist.github.com/renekreijveld/9663741
The line ". ${MYPATH}/joomlafunctions" is a sort-of include statement for Bash scripts. The joomlafunctions script figures out what Joomla version is running and sets some variables accordingly.

Won't parse configuration file.
CentOS 7, Joomla 3.6.
Manually typed database name works.

Hi Rene, found this forum by Google in search for finding pics in joomla's image folder which are unused. Have no idea how to install your code to make it work. So could you just step back from prof talk and tell a newbie how to use / where to put the code you provide here? Since it's the only hit for my search… Thanks, Herbert

Hello @HerKle,
I tried it out and after some modifications it is working now for me.

So here my Instruction:

1. in "jfindfiles" above the part:

result1=grep -c "$file2" ${dbdump} result2=grep -c "$file3" ${dbdump} if [[ $result1 = 0 ]]; then if [[ $result2 = 0 ]]; then echo $file2 >> ${notusedfile} else echo $file2 >> ${usedfile} fi else echo $file2 >> ${usedfile} fi

is not working for me. I got an error. I changed the code to:

if grep -c "$file2" ${dbdump} > 0 then echo $file2 >> ${usedfile} else if grep -c "$file3" ${dbdump} > 0 then echo $file3 >> ${usedfile} else echo $file3 >> ${notusedfile} fi fi

2. place the file "jfindfiles" in your wwwroot directory of your joomla page and give the file execution rights.
3. Place the file "jfunctions" (https://gist.github.com/renekreijveld/9663741) in your wwwroot directory of your joomla page and give the file execution rights.
4. excecute the "jfindfiles" in the command line of the server with:
   ./findfiles
5. You should not run it in the live enviroment when many users are on the page because the database dump take some resources.
6. after the script is finished you have to text files with the result.
7. remove the both scripts and the text files from the server finally, after downloading it.

Hi,

Thanks for this very useful script.

Here is my gist with @wehsemann modifications, with a script to delete files using the unused text file and with the howto

Hello,
I am not experienced in Linux, but I need to run this script with my Joomla.
So I launched it and got to the point that it works, but I get an error "Error creating database dump."

What can be the causes? How to fix it? I have diskspace available, so it's not the problem.

My system is Red Hat Enterprise Linux Server release 6.7 (Santiago)

Thanks

Thank you so much renekreijveld, wehseman and psyray!

With the usage comment by user psyray and his adapted files (as commented above) I was able to get it to work (I'm new to ssh).
I learned

• SSH access is needed for this (found on webhost help pages how to do that)
• putty (putty.org) is a nice program for SSH access
• with ls -lh there is a list of who owns the files and what the permissions are (the user that uses Putty has to have execute rights) and via ftp the chmod command changes the permissions

There were three errors for the jfunctions.sh file

grep: ./libraries/cms/version/version.php: No such file or directory
grep: ./libraries/cms/version/version.php: No such file or directory
grep: ./libraries/cms/version/version.php: No such file or directory

just because the version directory does not exist in in my Joomla 3.9.6 installation. That is not a problem at all though!
