If i'm writing a long command or just typing an extensive file path, is there any that i can "reuse" it with some command shortcut?
e.g:
1.cp /home/myuser/really/big/file/here/and/there.png /home/myuser/really/big/file/here/and/there.png.bkp
Do i really have to type it all over again?

Use brace expansion
cp /home/myuser/really/big/file/here/and/there.png{,.bkp}

Also, history expansion can work here:
cp /home/myuser/really/big/file/here/and/there.png !#:1.bkp
where the !#:1 part refers to the first argument of the command you're currently typing.

You can save lots of time typing that by using tab expansion, the tilde shortcut, and command history.
For instance,
~/r[tab]/b[tab]/f[tab]/h[tab]/a[tab]/t[tab]/
(where [tab] means "press the Tab key") would expand to
/home/myuser/really/big/file/here/and/there
You could also type
cp /home/myuser/really/big/file/here/and/there.png /some/destination
then press up-arrow and just change the last three letters of the filename

1+1 and you can go even shorter:
cp /home/myuser/really/big/file/here/and/there.{,.bkp}– Mike Fitzpatrick – 2011-06-08T22:53:25.213@peth: Oops, yes, you're correct. So we can actually go even shorter:
cp /home/myuser/really/big/file/here/and/there{,.bkp}:) – Mike Fitzpatrick – 2011-06-16T22:58:51.090
