Function to run a progress bar in zenity
First off, I'm a novice in bash...
I'm trying to make a progress bar in zenity to show progress of a file download. When complete, the progress bar should exit. I'm using a function for the progress bar. Any help appropriated.
My code is :
Code:
#!/bin/bash

progress_bar()
{

(
while :
do

# =================================================================
echo "# Uploading" ; sleep 2
echo "25"
echo "# Uploading" ; sleep 2
echo "50"
echo "# Uploading" ; sleep 2
echo "75"
echo "# Uploading" ; sleep 2
echo "99"
echo "# Uploading" ; sleep 2
done

)  |
`zenity --progress  --title="Progress Status"  --auto-close  --auto-kill 2>&1`
a=111
echo $a
(( $? != 0 )) && zenity --error --text="Error in zenity command."

exit 0
}

while :
do
  progress_bar &  `curl  -o "bigfile222"    <downloadurl> 2>/dev/null`

wait $(jobs -p)
done
exit
~
