Shell Programming and Scripting

Hi all,

I have programmed in VB before, and have recently moved on to Bash.

In VB there is a command:

Code:

SendKeys {F12} > "Show Help"
SendKeys {Y} > "Answer Yes"

Is there any way of doing this in Bash? (I need to send the Ctrl key into the script?)


Thanks in advance

Probably. What are you trying to do?

The Ctrl key doesn't send anything; it only modifies other keys.

I wanted to virtually send the command Ctrl & C into my script, as the case statement doesn't always end properly sometimes.

Unless there is a foolproof way to automatically end a script that I don't know about?

(I'm a VB programmer, and I've been thrown in at the deep end with Bash)

The way to send Ctrl+C to a process is by running this command:

Code:

kill -2 <process_id_of_the_script>

If you want the script to self detect when its stuck, you can spawn off another script in background (somewhere at the start of the main script) which will monitor the parent and based on some condition (which will define what is getting "stuck") will kill the parent.

You can also explore trap command - that provides signal handling facilities which you may find useful.
