3. Search files which begin with test

>>> ls -lRs | grep -i test*

by using '-i' option, you can display the information of location (folders)


or


>>> find . -name 'test*' -print

this would be searching from this present folder


4. Search files which begin with test and then remove all or them

>>> find . -name 'test*' -exec rm {} \;

-exec command ;       : Execute command.
{}                         : The string {} is replaced by the current file name
\                         : For escaping

From this present folder, change all of folder's permission to 755
