PowerShell: List Alias, Find Alias

PowerShell cmdlets can have aliases. For example, {dir, ls, gci } are all the same as Get-ChildItem .

List All Aliases

• Get-Alias → show all aliases
• Get-Alias *r → show aliases ending in r

(Get-Alias has alias gal)

Find Fullname

• Get-Alias alias → find the fullname of a alias alias. For example, Get-Alias dir
• help name → find the fullname of a name name. For example, help dir

List a Cmdlet's Aliases

• Get-Alias -definition cmdlet_name → list all aliases of cmdlet_name. For example, Get-Alias -definition get-childitem

List Functions

• Get-ChildItem function:* → list all functions.

Note, Get-ChildItem as aliases {dir, ls, gci}.

List Commands

PowerShell has over 200 commands. Often, you need to know if there's a command that does what you want. You can search them by Get-Command.

Get-Command → list commands. (Command means any of {cmdlet, alias, function, filter, script, app}.)

# list all commands
Get-Command

# list all commands whose name contains *z*
Get-Command *z*
