powershell - How can I run a command after a cd ($pwd changes)? -


i want run command going file .mything-rc in current directory. want check if file exist when cd.

i mean, command not going call set-location, want execute automatically if user call set-location... nvm in bash, when cd in folder .nvmrc automatically runs command nvm use ...

how can detect $pwd changed , run command?

you append custom scriptblock existing prompt function check directory change , whatever want:

$currentprompt = (get-command prompt).scriptblock $newlogic = { $global:old = $global:new; $global:new = get-location; if($null -ne $global:old -and $global:new.path -ne $global:old.path){ write-host "location changed '$global:old' '$global:new'." } } $newprompt = [scriptblock]::create("$currentprompt; $newlogic") function prompt { & $newprompt }

note relies on global variables should of course choose better variable name old , new.
