I'm trying to write a bash script using dialog, and part if it involves cloning a few git repositories.
I'd like to use dialog --gauge to show a progress bar as well as showing a --tailbox to show what git is up to.
So far I'm not having any luck getting the progress info from git into a form that dialog will understand.
This is what I've got so far:
git clone [email protected]:really-bit-git-repo output-dir --progress 2>&1 | cat > /tmp/gitprocfile &
cat /tmp/gitprocfile | grep "[0-9]\{1,2\}%" | awk '{print $7}' | dialog --gauge "Progress" 7 50
I end up with a file in /tmp/gitprocfile that looks like this
Cloning into 'output-dir'...

And a progress bar that sits at 0%.
Am I missing something about how to pipe/grep/awk the data from git into dialog, or is this approach just not going to work?
As I think my comment is really too long and unclear here is my udnerstanding:
git clone [email protected]:really-bit-git-repo output-dir --progress 2>&1 | cat > /tmp/gitprocfile &
Calling git and writing the output in a file, cat is not necessary here.
cat /tmp/gitprocfile | grep "[0-9]\{1,2\}%" | awk '{print $7}' | dialog --gauge "Progress" 7 50
Just after the prvious command, show the file one with cat and dot the grep etc. So you get the content of the file only once ...
If wanting a text output at end I would do:
git clone [email protected]:really-bit-git-repo output-dir --progress 2>&1 | tee /tmp/gitprocfile | grep "[0-9]\{1,2\}%" | awk '{print $7}' | dialog --gauge "Progress" 7 50
If the dialog is in antoher term than the gitcommand:
In terminal 1:
echo '' > /tmp/gitprocfile; git clone [email protected]:really-bit-git-repo output-dir --progress 2>&1 >> /tmp/gitprocfile &
In terminal 2:
tail -f /tmp/gitprocfile | grep "[0-9]\{1,2\}%" | awk '{print $7}' | dialog --gauge "Progress" 7 50
I'm not used to dialog, but at least I'm sure your attempt won't reload the file on change.
