[SOLVED] loop with zenity

defila · 08-18-2013, 02:18 PM

Hello guys,

I do have a little issue with my pseudo code. I am trying to copy files from one place to another and show the progress bar of the task, however the progress will start on 0% and change its GUI to 100% immediately (there is no progress on the bar), files were copied to desired location, I did not have issue with that.

Do you have any advice?

PSeudo code

Code:

#!/bin/bash

cd ~
for file in *.txt
do
echo "$file"
cp ${file} ~/test
sleep 0.1
done | zenity --progress --title="TXT" --text="uploading" --percentage="0"

pseudo-answer?

Code:

do_work ()
{
	cd ~
	for file in *.txt
	do
	echo "$file"
	cp ${file} ~/test
}

touch /tmp/$$
( ( echo 1 ; while [ -f /tmp/$$ ] ; do sleep 1 ; done ; echo 100 ) | zenity --progress --undecorated --no-buttons) & do_work
rm /tmp/$$

make the work a function, write a /tmp/$$ file ; while /tmp/$$ file exists; do work, then rm /tmp/$$

This "borrows" on The following example script shows how to create a progress dialog

"Stolen" from here...
I tried using zenity progress also at that link but I never could get a progress to show progress incrementally, so I just used yad (a zenity fork with more options) with a pulsate option instead.

Hope that helps...

Oh yeah,

Thanks for answer

quite clever way howto solve it. Anyway, I tried to execute it and will receive "error near unexpected token `}' "
I tried to play with it to find out if it is not executing some additional space e.g. like this:

Code:

dowork () {
	cd ~
	for file in *.txt
	do
	echo "$file"
	cp ${file} ~/test \
}

but then I will face "unexpected end of file". Did I miss something here?

is there any

Try this instead:

Code:

dowork () {
	cd ~
	for file in *.txt 
	do cp ${file} ~/test
        done
}

I'm guessing the "echo" was for a visual verification during "construction" of the program/routine?

Hah! I have find 'dull' workaround for it :}
I have created a function and send the output into zenity

Code:

.....
2>&1 | zenity --progress --auto-close --pulsate --title "Whatever"
.....

files are copied to location and it seems that the progress bar is reflecting the action (for the user) (--pulsate option does not really show the progress but since the output is redirected into zenity it will end automatically as it will finish)
it is not clever solution but it will help me now

hopefully nobody will read the pseudo-script :}}

Hi,
yes, it was for verification

and your version works as well, thanks :}
