hi all
i would like discuss about progressbar.
while am copying a file or folder..
to other directory or to other folder...
a window will appearing it showing progressbar..
here it showing file size and delay time..
how much it is copying and how much it is left.. like this..
i would like to use this..
i am copying a file to other folder..
using "cp -p", but it is not showing this progressbar window..
i would like to show this window..
can you please help me
thnak you in advance
do a "man cp", and you'll see it's not supposed to show a progress bar
This isn't strictly C related and should have gone in the Linux board. If you want it 'terminal based' then use a library like nCurses, or if you want it GUI based use GTK+ or Qt (or something else). As do get the status on just how much you've read / ETA, that is for you to find out, DO SOME RESEARCH !Quote:

Then in a loop, copy each file individually and then advance the progress bar by 100/n of a step, assuming your progress bar was calibrated in percentage terms.

how can i derive the pulses of progressbar?.
and what is 100/n?
i am storing the size in "char".
how can i divide this..
please help me
thank you in advance
I would change your size variable to something much larger than a char. I'm thinking your OS will have a default variable type for use with file sizes, and your compiler will support that type, also.Quote:

In your copy loop:
pseudo code:It looks nice if the progress bar has at least 10 char's in it's width, and no more than 30.Code:i = 0
while there are more bytes to be copied
i += 10
fgets() or fread() say 512 bytes, if available
and write it to the new file
fprintf() or fwrite()
if( bytes copied * 100 > i * total bytes to be copied)
print another progress char (ASCII char 176, 177, 178 in text mode, recommended).
loop back
thank you i did this progressbar pulse...
like (100/filesize in bytes) and am convering file size in to float value using atof()
but for 1.2M(1221948 bytes)
100/1221948=====
taking progressbar is very slow...
and here how can i know estimated time to copy perticular size of a file...
remaing time to copy a file....
can you please help me
thank you in advance
Well work out how many bytes your doing a second (on average)...
eg, for arguments sake, say you copy 10,000 bytes in 5 seconds, that's 2000 bytes/sec. And if you've got say 50,000 bytes to go thats an ETA of 50,000 / 2000 seconds
sorry for this..Quote:

i did copy paste.
with in 7 seconds i copied 100611257 bytes.
can you please explain it clearly..
thank you in advance
Okay,
* Equate how many bytes you're currently copying a second (preferably dynamically)
* Work out how many bytes you have to go, (TotalSize - BytesCopied)
* Then you can work out how long it's going to take to copy the remaining bytes, ((TotalSize - BytesCopied) / BytesPerSecond) seconds
You seem to do a lot of posting with little or no research and it's only landing you in strife
