====== A list of the most dangerous commands ====== With great power, comes great responsibility. - **rm -rf * ** - deletes all files and directories. Recursively. Always check that you are - not root - not in the root-directory - **dd** - according to the manpage, dd copies and converts. The problem arises with the fact that it can be used to copy and convert harddisk-partitions blockwise. Great power (harddisk-mirroring and more), but with great reposibility: If you accidently specify the wrong destination, you are in deep trouble! - **tar** - perfect for backups. But take care of where you are and which paths are stored inside the archive, or you can overwrite good, current data with good, **outdated** data. (That is, if you just want to recover **some** files from the archive, but unpack the whole bunch to a temporary location. You need to make sure that you **really are** in that temporary location.
