Deleting a directory
 

How do I manually delete a directory in terminal. For example I need to delete /opt/ibm/itm

If it's empty, you can use rmdir, i.e. "rmdir /opt/ibm/itm". If it isn't empty, you can use rm with the r and f flags, i.e. "rm -rf /opt/ibm/itm". See the rm and rmdir man pages as well. You'll likely need to be root to run these.

when deleting anything in directories such as opt/usr/bin etc. i like to use rm with the -v option to show what it's doing (if theres alot of files, i wonder if it hangs) and the -i (interactive, so i dont delete something by accident)

will tell you alot more about the command and it's switches
