When using the command I know a friend of mine who used to re-use last part of previous command. He unfortunately moved far away and I can't get hold of him.
First:
cp -r folder ~/folder
Then he was re-using ~/folder in a very quick way.
Anyone who knows how to do this?
The variable $_ is used to substitute the most recent parameter.
So, in the example you mentioned, you'd do something like:
cp -r folder ~/folder cd $_
cd $_ will change directory to the most recent parameter i.e. ~/folder.
For more such variables, have a look at https://stackoverflow.com/a/5163260/1626345.
With the arrow up key you can quickly access the last command you used.
With Ctrl+R you can do a 'reverse-i-search'. That means you just type in any letter or word of a command you already used and it will show up when enough identifying input is given.
Typing !$ will insert the last word (or a whole path if it's one) of the last command you used. See here for a lot of useful tips. I just bookmarked it. :)
If you are planning to do this quite often with the same paths, this tutorial might help.
