Hello,
I want to create a progress bar, which shows the progress of a copy
command.
So, how can I take the output of a copy command ?
Can anybody help in this regard ?
Thanks in Advance

If “cp” thinks its stdout is connected to a tty, then “cp -V” produces
output about once per second, which your program can capture and parse. You
can run a program like cp in such an environment using forkpty(). Note that
this is a somewhat advanced topic; the Stevens books or equivalent sources
on the web regarding pseudo-ttys may be helpful.

I would just re-implement the copy command in C. If you are not doing
anything tricky (like recursive directory copies or creating destination
directoies if they don’t exist) then it’s only about 5 lines of code.
Or grab the source for ‘cp’ and modify it to your requirements.
Personally I would find either of the above simpler than messing around with
forkpty().

Hello,
Thanks for the suggestions.
As I am doing Recursive copying, I think I have to go for forkpty().
I tried to divert the output of the cp -V to a text file, so that i can
use it in my app for capturing the status of copy. But when i do that, The
percentage of copy wont be displyed in the text file.
Could you pls give an idea of how can i implement forkpty() in my app.
Thanks you
