It won’t do anything for me. I try to use it and it just come right back to the prompt.

Open a shell prompt and just paste the code. Type the following (it will not work with wildcards)
cp_p /path/to/big/file.ext /copy/hereVivek,
This is cool and all, but the overhead of strace make this not very useful. rsync -av shows a progress bar. You can also get a progress bar if you use scp locally. Yes, scp supports local file transfers without using any network or connecting to a local sshd instance.
jeff@omniscience:~$ du -h windows.tar.bz2 822M windows.tar.bz2 jeff@omniscience:~$ time cp_p windows.tar.bz2{,.new} 99% [====================================================================================================>] real 2m18.957s user 0m11.589s sys 0m23.469s jeff@omniscience:~$ ls window* windows.tar.bz2 windows.tar.bz2.new jeff@omniscience:~$ time cp windows.tar.bz2{,.new2} real 1m39.597s user 0m0.096s sys 0m5.092sahh…. doesn’t work for me either dude. this totally sucks.. phuck this… dont waste ur time. I wanna crap on u so hard dude.
How i can use this script?
LOL at the nubs who can’t get this to work. Go back to your Vista box and stay there.
Only thing I had to do was set my terminal to ANSI. Also, the width of this progress bar is fixed, it will not scale with the width of your terminal.
Also note that for trivial transfers they might complete before the script has a chance to output the progress bar. So if the file copies and you didn’t see a progress bar, it’s because you didn’t need one.
yes scp and rsync are alternatives but this is very cool nonetheless. Thank you for posting it!
