copy files/directory and show it by progress bar (zenity/kdialog)

DoME69 · 05-06-2015, 05:12 AM

Hi,

I wrote script tcsh to copy files/directory.
what is wrong and why zenity not open?

Code:

#!/bin/tcsh -f

set src = `du -s $1 | awk '{print$1}'`
set des = "0"

cp -rp $1 $2
while ($src >> $des) 
set des = `du -s $2 | awk '{print$1}'`


echo `lua -e "print ( $des/$src *100 ) "`
echo $src
echo $des

end | zenity --progress --percentage=0 ;

Hello,
I am not very familiar with tcsh, but:

1/ First, you copy the files, _THEN_ you run some loop doing what?
2/ Doesn't tcsh use double quotes around parameters?
3/ What's the condition for the while loop? $src >> $des. Is that a bit shift?

Try it in bash using "set -x" like so:

Code:

#!/bin/bash
set -x

set src = `du -s $1 | awk '{print$1}'`
set des = "0"

cp -rp $1 $2
while ($src >> $des) 
set des = `du -s $2 | awk '{print$1}'`


echo `lua -e "print ( $des/$src *100 ) "`
echo $src
echo $des

end | zenity --progress --percentage=0 ;

run it from shell and watch the debug output for errors.
Let us know.

1. loop should get the progress number and show it at zenity.
2. no error found so i guess yes.
3. don't understand the problem

bash not work for me and i still want to use tcsh.

can anyone help?

Progress of what? The copying is already finished by the time the loop starts.

My point is, if quoting in tcsh works as it does in bash, which I assume it does, your script will break whenever the filenames contain spaces. So you should put double quotes around all the variables like "$1", "$2", etc. If I'm wrong pleas somebody correct me.

The problem is that the >> operator is a right shift (shifts bits in a variable to the right) in most languages (or a redirection). I believe in this context it would be the right shift. That doesn't make sense, maybe you meant $src > $des?

I tried to help and you told me what you didn't want.
Now I don't want to help you.
If you are not willing to take direction, why are you asking for help?

You're welcome, btw.

maybe using dd you can redirect its progress to be prompted to zenity.

Code:

#! /bin/sh
rm sometmp
dd if=/dev/urandom of=/dev/null 2>&1 > sometmp &
DD_PID=$!

while true
do
    /bin/kill -10 $DD_PID || exit
    sleep 1
    cat sometmp
done

rm pipe

too sleepy for context
(and idk zenity)

As stated your copy command completes before the loop starts and the syntax for zenity is incorrect. I would base the progress on number of files copied versus directory size. The following is psuedo bash but I think it gets the basic idea across.

Code:

 
for (( x<$no_files_to _copy )); do
  cp $file $destination
  echo "$(( (x * 100) / no_files_to_copy ))"
done | zenity --progress \
  --title="Copying Files to $destination" \
  --text="$file" \
  --percentage=0
