PowerShell run commands once in nested foreach
Hi,
I have a code similar to the below:
i want the echo "test" to only happen once within the first foreach. my real code contains powershell commandlets and i only want to execute these commandlets once per 1..3. so first loop will output 1, then it will go to the next foreach each which gives value a. within a, b, c, d, e. i want to echo test, however when it goes to 2 which is the first foreach, i dont want to echo test anymore. i hope this makes sense. How can this be achieved?
I have a code similar to the below:
foreach($a in @(1..3)){
echo $a
foreach ($b in @("a","b","c","d","e")){
echo "Test"
}
}

still need to test though
ASKER
can you give me an example of begin process end please.
thank you.
thank you.

apologies I mean begin process end for this scenario
ASKER
should $first be outside of the if statement?
In my example, line 8 could also be moved after the If statement (afer line 9), or after the second foreach loop (after line 10) but still with the first foreach loop.

thank you
This scenario doesn't really lend itself well to using begin, process, and end. But here's an example (didn't include end):
1..3 | ForEach-Object -Begin { echo "test" } -Process {
echo $_
foreach ($b in @("a","b","c","d","e")){
# blah
}
}
