Can you get cp to give a progress bar like wget?

For those of you interested in making it a permanent replacement for cp, you can use this Python script:

    #!/usr/bin/env python
    from sys import argv
    from subprocess import Popen
    copy_from = open(argv[-2],'r')
    copy_to = open(argv[-1],'w')
    Popen("pv", stdin=copy_from, stdout=copy_to)
    copy_from.close()
    copy_to.close()

Just alias cp to it in Bash.

Alternatively, you could just write a shell function:

   cp() { pv < $1 > $2; }

(Or name the function something else if you want regular cp still available.)

Ah, good point. I'm personally used to zsh, which doesn't have that particular misfeature.

Um... in what universe would you want an interactive terminal gadget to become the default implementation of cp? Yikes.

Still, nice pointer to the pv tool, which I hadn't heard of.

Still still, the linked awk snipped is awfully clever and more fun to read.

What? I think the override is fine in an interactive environment.

My team and I use a hack which overrides cd and as well as calling builtin cd it sources a script if it exists from cwd. This means you can get the exact enviroment you need for that working copy of a project.
