solved Terminal Command: How to prevent automatic `read` statement input/submission

[Archetyped]

I would like to open a new terminal window with Alfred to run a preset bash script (e.g. `my_script`).

 

The script has a confirmation prompt that affects the behavior depending on the value provided.

 

read -p "Start processing? (y/n): " conf_process

 

The script stops at this prompt when run directly from a terminal window.

However, when a script is run Alfred's Terminal Command action, it appears that the first `read` statement in the script is automatically executed without any input.

 

How can I run scripts via Alfred's Terminal Command without the first `read` statement being bypassed?

What is likely happening is that in your Terminal Command you added a newline, i.e. pressed ↩ at the end of the command. Thus that is being sent as well, and pressing a ↩ which is interpreted by read.

Thanks.  There was no explicit newline in the Terminal Command itself, but thanks to your comment, I started looking at the other actions that process the values sent to the Terminal Command action.

 

I learned that output from the Run Script action can add a newline unless it is explicitly suppressed.  Changing the final echo statement in that action to do just that resolved the issue:

 

echo -n "${output[@]}"

 

Thanks!

Run Script sends the script’s output without modifying it. echo does indeed send a newline without -n; printf sends without a newline unless you add one (\n) AppleScript and JXA always send a newline, except if you bend over backwards to avoid it. There’s a Transform Utility which can trim surrounding whitespace that will guarantee the newline isn’t passed to the next action.

Thanks for the tips 👍
