What is an equivalent of *Nix 'cut' command in Powershell?

Question

I have following content in a configuration file (sample.cfg),

Time_Zone_Variance(Mins):300
Alert_Interval(Mins):2
Server:10.0.0.9
Port:1840

I'm trying to store an each values after the : by using split in PowerShell. but i'm not able to produce require output.

Can someone tell me how to use PowerShell split for the above problem ?

Answer 1

You can read the contents of the file using Get-Content, then pipe each line through ForEach-Object, then use the split command on each line, taking the second item in the array as follows:

$filename = "sample.cfg"

Get-Content $filename | ForEach-Object {
    $_.split(":")[1]
}

Output

300
2
10.0.0.9
1840

Update

I prefer the approach by @AnsgarWiechers, but if you really need specifically named values you could create a hashtable and replace the name with the value:

$configValues = @{
    hour    = "Time_Zone_Variance(Mins)"
    min     = "Alert_Interval(Mins)"
    server  = "Server"
    port    = "Port"
}

Get-Content $filename | ForEach-Object {

    # Courtesy of Ansgar Wiechers
    $key, $value = $_ -split ':', 2

    foreach($configValuesKey in $($configValues.keys)) {
        if ($configValues[$configValuesKey] -eq $key)
        {
            $configValues[$configValuesKey] = $value
        }
    }
}

write-host "`nAll Values:"
$configValues
write-host "`nIndividual value:"
$configValues.port

Output

All Values:

Name                           Value

port                           1840                                                                                              
min                            2
