find command and multiple * usage
 

Please can i use:

find /home/username/public_html/_sub/*/wp-content/*cache* -type f -delete

command to empty all folders contianing "cache" in wp-content directory.

issue is that in /home/username/public_html/_sub/
i have around 50 folders and i want to use this rule on all of them, so im using *.

im asking there because im afraid could delete whole /_sub contents or similar horror story

i just want to empty folders containing cache in that wp-content directories

i cant say it my english is bad

is above command safe?

You could always check it by printing what files are found (and hence what would be deleted):

you can check this one, you can use cp or mv to make sure there is no disaster rather than deletion

find . -type f -name "some*.fil" -exec cp -iv {} /destination/folder \;
# or less likely...
find . -type f -name "some*.fil" -print0 | xargs -J % cp -iv /destination %
