I find --help usefulluseful as it lets me call help up while imI'm modding a command
For example
rsync -vPn ./* ./newfolder/.
Oh -- What is the dam flag for compress?
rsync -vPn --help ./* ./newfolder/. | less
I find the help command on flags sometimes very very usefulluseful and less time consuming. With man ive gotaI've got to type it in and the go back through my history to get back to the command I was in.
