I am writing a simple basic bash script (starting with #! /bin/bash, file format is .sh) and I am trying to make a progress bar work:

echo "You are running in LXDE mode. Answer 'yes' or 'no' on the following question to continue (or not) in LXDE mode."
zenity --question --text='Do you want to continue in LXDE mode?' --ok-label=Yes --cancel-label=No
echo "Please enter your username and password to continue because the following command needs root privileges."
zenity --password --username
echo "Please enter today's date:"
zenity --calendar --text="Please enter today's date:"
echo "Please enter your name:"
zenity --entry --text='Please enter your name on the text entry below:'
echo "Analyzing data..."
zenity --info --text='Now begin analyzing data. If it takes more than 40 seconds, click on "Cancel".'
zenity --progress --title='Analyzing data...' --pulsate

I have tried to make it move from 0% to 100%, and nothing happened. It was stuck at 0%. I have also tried to make it pulsate by using the --pulsate option, still at 0% doing nothing.

Can anyone please help me? Any help would be appreciated.

    Please edit your original question in order to show your bash script, if you need more detailed help than via the link to the zenity docs, (help.gnome.org/users/zenity/stable/progress.html.en).

    You didn't say how "you tried to make it move from 0 to 100". More importantly like @sudodus requested post your code so we can critique it. Jul 1 '17 at 16:43
  • @WinEunuuchs2Unix I cannot upload the .sh script file right now. Maybe tomorrow. See you tomorrow, then!

  • @sudodus I am going to upload the script to Google Drive today, edit the post and type the link.

    I could not open your script from my phone. Google says File type not supported for both links. Why not copy script directly into your question? Jul 6 '17 at 14:55

The Zenity docs have a small code snippet that should do exactly what you're looking for.

echo "10" ; sleep 1
echo "# Updating mail logs" ; sleep 1
echo "20" ; sleep 1
echo "# Resetting cron jobs" ; sleep 1
echo "50" ; sleep 1
echo "This line will just be ignored" ; sleep 1
echo "75" ; sleep 1
echo "# Rebooting system" ; sleep 1
echo "100" ; sleep 1
) |
zenity --progress \
  --title="Update System Logs" \
  --text="Scanning mail logs..." \

if [ "$?" = -1 ] ; then
        zenity --error \
          --text="Update canceled."

First try just copying in the code that's there and running it and confirming that it works as intended, then modify to add in your code where appropriate.

If your progress bar is stuck at zero, make sure to by-pass any sections of the script that may be hanging and making you think that it's actually working!

Edit: As stated in the Answer below, the reason it's not working is because zenity expects the progress to be echoed to it, like in the code sample.

  • You're right. Fixed, I think.

The way zenity works for displaying progress bars is capturing your echo commands from your bash script via the | (pipe) redirection command (symbol).

Here is an example you can try that I lifted from Ubuntu Forums:


# Force Zenity Status message box to always be on top.

# =================================================================
echo "# Running First Task." ; sleep 2
# Command for first task goes on this line.

# =================================================================
echo "25"
echo "# Running Second Task." ; sleep 2
# Command for second task goes on this line.

# =================================================================
echo "50"
echo "# Running Third Task." ; sleep 2
# Command for third task goes on this line.

# =================================================================
echo "75"
echo "# Running Fourth Task." ; sleep 2
# Command for fourth task goes on this line.

# =================================================================
echo "99"
echo "# Running Fifth Task." ; sleep 2
# Command for fifth task goes on this line.

# =================================================================
echo "# All finished." ; sleep 2
echo "100"

) |
zenity --progress \
  --title="Progress Status" \
  --text="First Task." \
  --percentage=0 \
  --auto-close \

(( $? != 0 )) && zenity --error --text="Error in zenity command."

exit 0
