Hi,

how can I set the prompt in PowerShell?



I use [%computername%]$s[%username%]$s$d$s$t$h$h$h$_$m$p$_$+$g with cmd and
would like something smilar in PS.

thanks, Robert

Could you show the prompt as you would like it to appear in the shell? In
general you just create a "prompt" function in your profile and have it
create whatever string you want. Here is what I use:

function prompt {
# Display the history ID number of the next command
$history = @(get-history)
if ($history.Count -gt 0) {
$lastItem = $history[$history.Count - 1]
$lastId = $lastItem.Id
}
$nextCommand = [int]$lastId + 1

# Does the current user had admin privileges
$currentUser = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$principal = new-object
System.Security.Principal.WindowsPrincipal($currentUser)
$isAdmin =
$principal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

if ($isAdmin) { $sep = "#" } else { $sep = ">" }

# Determine what nesting level we are at (if any)
$nestingLevel = ''
if ($nestedpromptlevel -ge 1) {
$nestingLevel = "[${nestedpromptlevel}]"
}

# Output prompt string
"[$(get-location)]`n" +
"$nextCommand" + $nestingLevel + " $sep "
}

set prompt=[%computername%]$s[%username%]$s$d$s$t$h$h$h$_$m$p$_$+$g

produces this prompt if C: is a local drive:

[ROBERT] [Bob] 16.08.2006 19:17:16
C:\WINDOWS\system32
++>

produces this prompt if X: is a network drive:

[ROBERT] [Bob] 16.08.2006 19:17:16
\\SERVER\C$ X:\WINDOWS\system32
++>

The ++ indicates that I'm two levels deep in pushd.

Thanks for your infos so far.

regards, Robert

function prompt
{
# display Computer name, username and the date time
write-host -NoNewLine "[$($env:ComputerName)] [$($env:UserName)]
$(get-date)`n"
# Add a logic for displaying Network path for Network drive
# not implemented...

# display current working directory
write-host -NoNewLine "$(pwd)`n"

# display Stack level
Write-Host -NoNewLine ("+" * ((Get-Location -Stack).count))
">"
}

Uhm, I am not sure how to resolve a network path for network drive...
but once I figure out how to retrieve a network drive path, it won't be hard
to add that functionality.

Anyways, above should be close to what you wanted(you can change "get-date"
to produce other date format if you want to...

I think the idea of the prompt function is to return a string that
PowerShell then writes to the host. So you might modify this to:

function prompt
{
$prompt = "[$($env:ComputerName)] [$($env:UserName)] $(get-date)`n"
$result = net use "$($pwd.drive):" 2> $null
if ($?) {
$result[1] -match "Remote name\s+(?<name>.*)" > $null
$matches.name + " "
}
$prompt + $(pwd)`n
$prompt += "+" * ((Get-Location -Stack).count
$prompt += "> "
$prompt
}

that certainly is a better of a practice since it reduces the calls to
write-host dramatically, and also improving "prompt" function efficiency(mine
sometimes takes a while to refresh ;p)

Thank you for the "Best Practices" there, I appreciate it.
I really want more over these Best Practice cases... and apply them to
PowerShell...
