cp progress bar

edwardsiow · 01-24-2006, 09:10 AM

Hi,
I have to copy large files from a CD to the hard disk.

I want to use a progress bar to display the status of
copying the files.

Any one has ideas about implementing this in shell script.

One may use a GUI based file manager for that. I.e. Nautilus (Gnome) or XFE (http://roland65.free.fr/xfe/), etc.

thanks for your advice

i have found a sample code in this forum

Code:

#!/bin/bash

files=`ls -l | wc -l`
copied=1
clear
echo "                     Please wait, copy in progress"
while [ $files -ge $copied ] ;do
   pct=$((100 * copied / $files))
   copied=$((copied + 1))
   echo -en ".$pct%\b\b\b"  ## you can use # or anything instead of dots 
   sleep 1
done
  echo -e "\n"
  echo "                     The operation is complete"
  echo -e "\n"

but i don't know how to modify this code so that i can use it to copy large files from a CD to the hard disk and at the same time showing the progress bar.

anyone can help me, please...

Here's another sample which maybe abit more usefull.

Code:

#!/bin/bash
# File copy with progress indicators
# Example: ./test original_file destination_file

usage()
{
   echo "Usage: $0 original_file destination_file"
   exit 1;
}

test $# == 2 || usage

echo Preparing to copy
orig_size=$(stat -c %s $1)

>$2
dest_size=0
cp -f $1 $2 &

while [ $orig_size -gt $dest_size ] ; do
   dest_size=$(stat -c %s $2)
   pct=$((( 100 * $dest_size ) / $orig_size ))

if [ $pct -lt 10 ] ; then
   echo -en "#  $pct%\b\b\b\b"
else
   echo -en "#  $pct%\b\b\b\b\b"
fi
sleep 1
done
echo

And here is another....

Code:

#!/bin/bash
# Example: ./test original_file destination_file
usage()
{
   echo "Usage: $0 original_file destination_file"
   exit 1;
}

test $# == 2 || usage
orig_size=$(stat -c %s $1)

>$2
dest_size=0
cp -f $1 $2 &

while [ $orig_size -gt $dest_size ] ; do
   dest_size=$(stat -c %s $2)
   pct=$((( 69 * $dest_size ) / $orig_size ))

    echo -en "\r["
    for j in `seq 1 $pct`; do
        echo -n "="
    done
    echo -n ">"
    for j in `seq $pct 68`; do
        echo -n "."
    done
    echo -n "] "
    echo -n $((( 100 * $pct ) / 69 ))
    echo -n "%"
done
echo

thanks for your resources..

i am sorry to tell that i am newbie and not so understand the above sample codes..

maybe you will ask me to go back study hard..but i really need to solve this problem urgent and dont have time for me to study. believe or not depend on you...

below code is easy for me to understand:

Code:

#!/bin/bash
umount /mnt/cdrom
mount /mnt/cdrom
mkdir ~/Desktop/CDcontents
cp -R /mnt/cdrom/  ~/Desktop/CDcontents/
eject /mnt/cdrom

but i don't know how to modify n put into the sample codes you provided above..if you don't mind, please give me guidiance..

thanks again..

Example: ./test original_file destination_file

This part is the name of my script ------> ./test
To use ./test , I made it execute with the command: chmod +x test
or you could use the method of : sh test

original_file ---------> Is actually a directory in your case.
that is /mnt/cdrom

destination_file --------> Is actually a directory in your case.
~/Desktop/CDcontents/

So, it might look like this...
./test /mnt/cdrom ~/Desktop/CDcontents/

Because it's a directory, you may need to play with the copy statement. Look into man cp for that. Maybe something like.....
cp -R $1 $2 &

Here is something that look similar, "catenate with progress":

You can use MC (Midnight Commander). The worlds best console file manager.

To install mc on ubuntu, enable the universe repository from /etc/apt/sources.list by removing the # before the universe repository.

Then simply say
sudo apt-get install mc

and then type mc on the command line to open up the colsole app.

    echo -n $((( 100 * $pct ) / 69 ))
    echo -n "%"

This works well for file->file, but file->directory will result in an endless loop you have to ctrl-c out of:

Code:

[mk6032@linuxquestions]# cp movie.avi /srv/nfs/media/video/
Preparing to copy
/root/cp_progress.sh: line 16: /srv/nfs/media/video/: Is a directory
###########################################################  0%
[mk6032@linuxquestions]#

It needs to run a check on the destination first:
if [ -d $2 ] then ....

Here it's a little improvement of the script; it should work if the second field is a directory now.

adam2508 · 03-09-2009, 02:58 PM

what does:
>"$d"

does?
I understand everything else, i just dont know what ">$d" by itself does.
can someone explain?

thank you

michelemase · 03-10-2009, 03:26 AM

It should create an empty destination file; the script also works without it.
Try it!

nonzenze · 04-28-2009, 11:27 AM

rsync -rv <src> <dst> --progress:

-r for recursive (if you want to copy entire directories)
src for the source file (or wildcards)
dst for the destination
--progress to show a progress bar

Honestly, rsync is only a little slower than cp for local copies and is so much better featured.

treehead · 05-07-2009, 02:46 PM

You can also look at pv (Pipe Viewer), but honestly, for the specific solution you're looking for--copying a tree of files off a CD-ROM with a progress bar--rsync is the best solution, as nonzenze said.
