Processing used in scheduled powershell scripts - powershell

I want a powershell script to run hourly. Am I best to run the script all day at startup and use sleep to run the code hourly or am I best to use a Windows scheduled task to execute and then close the script?
Which is better for not slowing the PC down?

Run a bat file when a specific application is opened in Windows XP

I want to know how can we run a bat file when a specific application is opened?
Eg: I would like to run a bat file whenever mspaint is opened.
I have successfully performed this in Windows 7 and Windows 10 using Task Scheduler. But the task scheduler available in Win Xp is very basic.
You could use another batch file that runs on startup of windows. use while loop with an appropriate sleep to detect when Paint.exe runs.
then you could write more commands to do anything you want. For example, as you said, you could run another batch file...
I found this solution by an investigation of these topics:
Syntax for a single-line Bash infinite while loop
How to check if a process is running via a batch script
Batch program to to check if process exists

Jenkins - Close the Jenkins job as soon as one of the parallel scrips fail

I'm running two Perl scripts in parallel in Jenkins
some shell commands
perl script 1 &
perl script 2 &
wait
some more shell commands
If one of the perl scripts fail in the middle of the execution , the job waits until the other script runs (as it is executed in parallel in background).
I want the job to stop as soon as one of the script fails and not waste time by completing the execution of other script.
Please help.
You set up a signal handler for SIGCHLD, which is a signal that is always delivered to the parent process when a child exits. I'm not aware of a mechanism to see which child process exited, but you can save the subprocess process identifiers and just kill both of them when you receive SIGCHLD:
some shell commands
perl script 1 &
pid1=$!
perl script 2 &
pid2=$!
trap "kill $pid1 $pid2" CHLD
wait
some more shell commands
The script above has the downside that it will kill the other script regardless of the exit status of the subprocess. You could in the trap, if you want to, add a check for the exit status. The subprocess could e.g. create some temp file if it succeeds and the trap could check if the file exists.
Typically with Jenkins you would have the parallel steps running as separate jobs (or projects as they are sometimes known) rather than steps in a job. This would then allow the steps to run in parallel across different slave machines and it would keep the output for the jobs in a separate place.
You would then have a controlling job running the other parts.
I like the Multijob plugin for this sort of thing.
There are alternatives which may suit better, such as Build Flow Plugin which uses a DSL to describe the jobs you want to run

Is there a way to schedule a SikuliX script to run automatically?

I've managed to run the script from the command line thinking that i could possibly use windows Schedule Task to run it, but it doesn't run command prompt or anything. When i go and check the task it says it completed. Im running windows8. Any help would be appreciated.
You can make a .bat file to execute your sikuli sript. .bat files can be scheduled with Windows 8, but you may need to schedule that task as SYSTEM or as the admin.

How to invoke an opened Exceed window to run a Perl script using a Schedule Task

TASK TO BE ACCOMPLISHED:
To schedule a perl script which is executed on a specific time / day in a week
THINGS I HAVE DONE:
In a schedule Tasks, I have created a new Task by which the Task will call a batch file with below contents
cd "DRIVE\FOLDER\Hummingbird\Connectivity\14.00\Exceed\"
ABCD.xs
cd mDrive/bin
perl baseline.pl -publish -location XXX -email
THINGS NOT WORKING FOR ME / CAUSING THE ISSUE:
Wen I run the scheduler, the prompt opens up the ABCD.xs exceed file window seperately file but the below commands are executed in the command pronpt itself
EXPECTED OUTPUT:
I want the commands
cd mDrive/bin
perl baseline.pl -publish -location XXX -email
to be executed in the exceed window
Any kind of solution wud be great
Thanks in advance.

Sounds like you need to start getting into either SendKey stuff (Win32 packages) or else look into writing Exceed/Hummingbird scripts and just executing those.
Some other things to look into... does the remote server have a telnet or ssh server running? Or are there other methods of executing code on the remote server?
For example, my work's mainframe is accessed via a Hummingbird terminal emulator, but I can also telnet to the mainframe and execute commands as well as FTP batch job directly into the JES spool. So when I execute things on the mainframe by way of my PC (Perl scripts, etc.), I don't even fool with Hummingbird.
Good luck...

simple command prompt one line into exe

I have a perl script that I run from the command prompt: 3 times a day, the problem is now I need to run it every two hours. Im not going to be on an episode of lost so I need some help. Here is the command:
Perl C:/test/scripts/edi.pl
Does anyone know how this above one line command can be made into an executable (.exe) file so I can use the task scheduler to run?
If there is another way to do this with the task scheduler to run once every two hours every day then I could do that as well.
Thanks for your time.
Can you not simply create a batch file that runs the script, and set that batch file to run every two hours? I know from a quick test there that I can schedule a batch file to run from Task Scheduler on Windows XP at least.
You can actually use the task scheduler to run that exact command without a batch.
The task scheduler should allow you to pass some arguments to the script without a problem (I have done this on a few Windows servers in order to have them run PHP scripts)
