powershellsplitpowershell-2.0

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


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 ?


Solution

  • 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                                                                                                 
    server                         10.0.0.9                                                                                          
    hour                           300
