Bash script to PowerShell NET-SNMP - bash

Question

I have an issue changing an script I did in bash to powershell, the script is the following:
#! /bin/sh
for IPVAR in 172.27.41.202 172.27.41.203
do
TIEMPO=$(date +"%m-%d-%y")
FILENAME=${IPVAR}_${TIEMPO}
date +"%c" >> $FILENAME.txt
snmpget -v 2c -c public $IPVAR -mALL 1.3.6.1.4.1.41413.1.1.0 1.3.6.1.4.1.41413.1.4.0 1.3.6.1.4.1.41413.1.2.0 1.3.6.1.4.1.41413.1.3.0 1.3.6.1.4.1.41413.10.3.4.1.1.1 1.3.6.1.4.1.41413.10.3.4.1.2.1 1.3.6.1.4.1.41413.10.3.4.1.3.1 1.3.6.1.4.1.41413.10.3.4.1.4.1 1.3.6.1.4.1.41413.10.3.4.1.5.1 1.3.6.1.4.1.41413.10.3.4.1.6.1 1.3.6.1.4.1.41413.10.3.4.1.7.1 1.3.6.1.4.1.41413.10.3.4.1.8.1 1.3.6.1.4.1.41413.10.3.4.1.9.1 1.3.6.1.4.1.41413.10.3.4.1.10.1 >> $FILENAME.txt
done
In my Linux enviroment works fine but I installed NET-SNMP in a Windows Server because there is where we need the files to be but I can seem to make it work I did this:
$IPS = (10.96.90.2)
$TIEMPO = get-date -f yyyy-MM-dd
Foreach ($IPVAR in $IPS) {snmpget -v 2c -c public -m ALL $IPVAR 1.3.6.1.4.1.41413.1.1.0 1.3.6.1.4.1.41413.1.4.0 1.3.6.1.4.1.41413.1.2.0 1.3.6.1.4.1.41413.1.3.0 1.3.6.1.4.1.41413.10.3.4.1.1.1 1.3.6.1.4.1.41413.10.3.4.1.2.1 1.3.6.1.4.1.41413.10.3.4.1.3.1 1.3.6.1.4.1.41413.10.3.4.1.4.1 1.3.6.1.4.1.41413.10.3.4.1.5.1 1.3.6.1.4.1.41413.10.3.4.1.6.1 1.3.6.1.4.1.41413.10.3.4.1.7.1 1.3.6.1.4.1.41413.10.3.4.1.8.1 1.3.6.1.4.1.41413.10.3.4.1.9.1 1.3.6.1.4.1.41413.10.3.4.1.10.1 >> "$IPVAR_$TIEMPO".txt}
If I run only the "snmpget" command it works fine but I have troubles with the scripting part here.
Hope you can help me.

Try the code below (this hasn't been tested as I don't have snmpget, but the method works with other command line apps):
$IPS = #('172.27.41.202', '172.27.41.203')
$IPS | ForEach-Object {
$snmpgetParams = #(
'-v', '2c' ,'-c' ,'public' ,'-m' ,'ALL', $_, '1.3.6.1.4.1.41413.1.1.0 1.3.6.1.4.1.41413.1.4.0 1.3.6.1.4.1.41413.1.2.0 1.3.6.1.4.1.41413.1.3.0 1.3.6.1.4.1.41413.10.3.4.1.1.1 1.3.6.1.4.1.41413.10.3.4.1.2.1 1.3.6.1.4.1.41413.10.3.4.1.3.1 1.3.6.1.4.1.41413.10.3.4.1.4.1 1.3.6.1.4.1.41413.10.3.4.1.5.1 1.3.6.1.4.1.41413.10.3.4.1.6.1 1.3.6.1.4.1.41413.10.3.4.1.7.1 1.3.6.1.4.1.41413.10.3.4.1.8.1 1.3.6.1.4.1.41413.10.3.4.1.9.1 1.3.6.1.4.1.41413.10.3.4.1.10.1'
)
$TIEMPO = Get-Date -f yyyy-MM-dd
$FILENAME="$_`_$TIEMPO`.txt"
snmpget #snmpgetParams | Set-Content $FILENAME -Force
}
Line 1 declares an array of IP addresses.
Line 2 starts a foreach loop which will iterate through each IP in the $IPS array.
Lines 3,4,5 create an array of parameters to pass to the snmpget command. The $_ parameter is the current IP address within the loop.
Line 7 sets the $TIEMPO variable with the date.
Line 8 sets the $FILENAME variable with the IP address, followed by an underscore, followed by the date. The backticks ` tell PowerShell to not treat the following characters as part of the preceding variable name. An example filename: 172.27.41.202_2016-08-31.txt
Line 10 calls the snmpget command. The #snmpgetParams 'splats' the parameter array. The output is piped into the Set-Content command, which, with the Force option creates or overwrites the file contents for that IP & date.
Line 11 closes the loop.
