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:

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 -h
It 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

About linux screen program. Really nice to have it but usually when I find some article about using some linux software, there are always some missing pieces and then I have to search google again and again and that’s not good.
Type:
screen -> it opens up new screen window and you are in it
ctrl +a is for switching windows
ctrl+a c is for creating new screen window
Now to close it (detach) use:
ctrl+a d
To list all current screens:
screen -ls
To reattach to it use:
screen -r (number)
To close it use:
screen -XS (number) quit

rsync -avz files/app_akcijekatalozi –exclude=storage/ akcijekatalozi@domain.net:/home/akcijekatalozi/
Take note, exclude path storage/ is relative to files/app_akcijekatalozi path…not root path, home path or absolute path!
I’ve been trying to figure this out for the last 2 hours. But I have finally managed to install it.
From offical composer page copy paste first two lines
https://getcomposer.org/download/
like:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'c31c1e292ad7be5f49291169c0ac8f683499edddcfd4e42232982d0fd193004208a58ff6f353fde0012d35fdd72bc394') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
Then, since KeyHelp makes users folders as root you will need to use i.e. files folder for installing Composer with command above. Then use this command:
COMPOSER_HOME=/home/users/someuser/files/ php composer-setup.php
What this command does?! COMPOSER_HOME is var and enables you to write composer.phar inside different home path.
All this without root. That was the point in the first place. Root and composer are not good option.
Problem was with the permissions in the first place. Users are from root. And Composer wanted to use $cd to access home folder. It poined to /home/users/someuser (someuser is current logged in user).
Error: Unable to create Composer home directory “/home/users/someuser/.config/composer”: mkdir(): Permission denied
