Show command progress with output of command?

[John Riordan]

Hi All,

What are the best ways to pipe output of command to YAD progress?  I know you need to lead this output with a # so YAD can capture it. I have tried and tried so many different options but can't seem to get it.  Any suggestions would be so welcomed. 

Thanks in advance,

John

Pipe or Coprocess

https://gist.github.com/Misko-2083/46108de792972a5d451f

#! bash supports only one coprocess

One more thing, yad expects new lines but when using non-interactively,

most standard commands,like grep, buffer the output,

meaning it does not write data immediately to stdout.

It collects large amount of data (depend on OS, in Linux, often 4096 bytes) before writing.

Grep has an option to turn on line buffering:

command | grep --line-buffered | command

With command that does not have option to modify buffer, you can use GNU coreutils stdbuf

tail -f <file> | stdbuf -oL fgrep "string" | sed 's/stuff//g'

With awk you can use fflush() function to unbuffer the output.

Here is -tails in action   (I am not a programmer but,)  I was able to: STOUT --> File --> Yad Parent using -tails. I did this 5 years ago. I can share my code if others will improve on it.

Still looking for code but, here is another video of feedback in action.

Wow thanks so much. I had to do with out the progress I was looking for. However, I would still like to add that piece in the future.  Thanks again!

John, I could not find my original code so I spent a few hours (I'm old and slow and not a programmer) to rework my terminal feedback script. This is only the main code, I will upload the complete code (multiple files and directories) to my github account and post link next post. 

Here is video of complete code in action: https://rumble.com/v1h3h21-yadgui-terminal-feedback-updating-code-yad-and-bash.html 

(Starts about 50 seconds)

The below example code opens a yad --text-info window and using -tails command feeds function output, echo, wget -o, etc to the text-info window.  

You will see "yad4" in the below code and its another copy of yad that can be killed with "killall yad4". This way you can have subsets of yads running and close those subsets easily.
