When removing old files from server and then update mysql:
UPDATE`catalogues`SET`active`='0'WHERE validnost_end_date <='2021-02-01 00:00:00';Delete duplicate entries mysql
delete t1 FROM cataloguestext_2 t1
INNER JOIN cataloguestext_2 t2
WHERE
t1.id < t2.id AND
t1.page = t2.page AND
t1.catalogues_id = t2.catalogues_id;

Adminer without password
Very important sometimes.
Download adminer .php and then change this on line 1152.
login($_e,$F){if($F==””)return to login($_e,$F){if($F==”abc”)return.
Save and you are good to go. Delete after everything has been setup and working ok.
Change character in filename linux bash
I’m figuring this out for some time. It’s not that I can’t read but most of the time when trying out bash stuff you can make more damage then good to your system so you have to be really really easy.
Now, this one here makes the difference. I had a job to change & in many many many files in different directories and subdirectories and after trying many scripts this one came up working just fine and fast.
find . -type f -exec rename 's/string1/string2/g' {} +If you want to target specific filename extension then you need to add:
find . -type f -name "*.webp" -exec rename 's/&/-/g' {} + It was taken from here:

Bash script for transferring files

rm -rf $db_database*

#rsync -avz -e "ssh -p 4444" /home/users/nikola/www/somedomain.com/ nikola@$url:/home/users/nikola/www/somedomain.com/Mogrify and delete all from current folder and subfolders
Here is some nice code for converting all jpg to webp and also code for deleting all files excluding .webp or any other you want. This is for my personal reference 🙂
nohup find . -type f -regex ".*\.\(jpg\|jpeg\)" -exec mogrify -quality 40 -format webp {} \; -print &
find . -type f ! \( -name "*.webp" \) -exec rm -rf {} \;Biggest folders in current path
If you need to find what is the biggest folders in current path in linux then this is the command:
du -sh * 2>/dev/null | sort -hIt needs couple of seconds to calculate (if you have slow io vps or hdd) and this is what you get:
root@vps3345:/home/nick/web# du -sh * 2>/dev/null | sort -h
