Question

In Powershell given the following string

$string = "this is a sample of 'my' text $PSP.what do you think"

how do I use the -replace function to convert the string to

this is a sample of 'my' text Hello.what do you think

I obviously need to escape the string somehow, Also $PSP is not a declared variable in my script

I need to change all mentions of $PSP for some other string

Answer 1

Use the backtick character (above the tab key):

$string = "this is a sample of 'my' text `$PSP.what do you think"

To replace the dollar sign using the -replace operator, escape it with backslash:

"this is a sample of 'my' text `$PSP.what do you think" -replace '\$PSP', 'hello'

Or use the string.replace method:

$string = "this is a sample of 'my' text `$PSP.what do you think"
$string.Replace('$PSP','Hello)'

this is a sample of ‘my’ text Hello.what do you think
