Monitor logs in Linux using Tail
Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option.

scp with compression.
-C is for compression.

count processes with status "D" uninterruptible sleep

VIM subst any char different from literal " + EOL with searched string + white space
---- this line ends here but must be concatenated with this one "this line ends here" and should NOT be concatenated with this one
