These demographics are not representative of all students in American classroom settings, which continue to grow in diversity. uname :įor example, uname -a outputs the OS, the hostname, the kernel version and the architecture.Currently, the public school workforce in the United States is predominantly white, middle class, and female. Many cmdlets have built-in parameters which allows to filter the objects, but the generic filtering mechanism is the cmdlet Where-Object.įor example, to filter the processes which have a working set of more than 100 MB, you would run the following :Ĭ:\ > Select-String -Path 'C:\Windows\iis.log' -Pattern 'Failed' Windows\iis.log:11: Failed to create iisCngConfigurationKey key container ( result = 0 x8009000f ) Windows \iis.log:21: Failed to create iisCngWasKey key container ( result = 0 x8009000f ) Windows \iis.log:76: Failed to create iisCngConfigurationKey key container ( result = 0 x8009000f ) Windows \iis.log:80: Failed to create iisCngWasKey key container ( result = 0 x8009000f ) Windows \iis.log:679: Failed to update the DynamicIPRestrictionModule globalModule ( ignoring failure ) ( result = 0 x80070490 )Īnd if you are a regular expression nerd, you can feed them to the Pattern parameter. No text-parsing required here, unless you are dealing with objects of the type. In Powershell, most of the time we are dealing with objects so this translates to : filtering the objects which have 1 or more value(s) in a property. Think about what you are trying to achieve when you use grep : filtering lines of text which contain a specific value, string, or pattern. This is the one I get asked about the most : For this, there is the Wait parameter, which was introduced in PowerShell 3.0 as well. This parameter was introduced with PowerShell 3.0.Īn exceedingly valuable usage of the tail command for troubleshooting is tail -f to display any new lines of a log file as they are written to the file. The Tail parameter has an alias : Last, this makes this parameter more discoverable for those who Tail would not even cross their mind because they don’t have a Linux background. We can use its aliases : cat, gc or type. Note that even when we run this cmdlet against a text file, this doesn’t output plain text, this outputs one object of the type for each line in the file. So, in the example above, $_ stores the value 1, then it stores the value 2, then the value 3 and finally the value 4. In case you are wondering what is the $_ in the example above, it is a representation of the object currently being processed, which was passed from the pipeline. pwd :Ĭ:\ > 1.4 | ForEach-Object once for every object passed to it via the pipeline. Besides, this is an opportunity to illustrate fundamental differences between bash and PowerShell. Still, I’m going to do this translation exercise for a few basic commands because it can be an interesting learning exercise for bash users coming to PowerShell. Powershell gives us rich objects with properties and methods to easily extract the information we need and/or to manipulate them in all sorts of ways. So quite often, translating the bash way of doing things to PowerShell is the bad way of doing things. When we run PowerShell cmdlets we get objects. When we run bash commands or external executables in bash, we get plain text. So their cat and their grep are near and dear to their heart and their first reflex when they get into PowerShell is to replicate these commands.įirst, this is not always a good approach because bash and PowerShell are fundamentally different. The majority of my colleagues have more of a Linux background than Windows. PowerShell equivalents for common Linux/bash commands
