Over the years, I’ve managed thousands of websites at once, so I’ve found myself in the position where I need to perform some investigative tasks like
- Find old directories and how big they are.
- Find all the debug.log files that WordPress generates.
- Find any file larger than a specific size.
- Change a bunch of configuration files at once.
Find directories older than 30 days and tell me how big they are
find . -maxdepth 1 -mtime +30 -type d -exec du -sh {} \;
Find all debug.log files along with the size of the files
find . -name debug.log -type f -exec du -sh {} \;
Find files larger than 500MB in size
find . -size +500M -type f -exec du -sh {} \;
Find files larger than 500M and then delete them
find . -size +500M -type f -exec rm {} \;
Go through a bunch of config files and change a setting in all of them. This is an example of php-fpm pools
find . -type f -name "*.conf" -exec sed -i 's/pm.max_children = 15/pm.max_children = 1/g' {} \;
Similar as above but for wp-config files. This will change the ip address a constant points to
find . -type f -name "wp-config.php" -exec sed -i 's/10.84.72.76/10.223.242.21/g' {} \;
