If you have scripts deleting/moving or otherwise playing around with
the filesystems you might want to double check they are null safe for
variables that end up filenames...
example:
#!/bin/bash
MYFILE=$1
scp ${MYFILE} m...@backup:
rm -fr ./${MYFILE}
Very basic but illustrates the point.... if the bash argument (in this
case) was invalid or missed out somehow the result could be the
removal of the entire PWD. This only gets worse with absolute paths
(oops bye bye /) and more complicated setups... when quickly scripting
it is also something that often gets overlooked....
