Replace substring in PowerShell
PowerShell strings are just .NET strings, so you can:
PS> $x = '-foo-'PS> $x.Replace('-', '&')&foo&
...or:
PS> $x = '-foo-'PS> $x.Replace('-foo-', '&bar&')&bar&
Obviously, if you want to keep the result, assign it to another variable:
PS> $y = $x.Replace($search, $replace)
The built-in -replace
operator allows you to use a regex for this e.g.:
C:\PS> '-content-' -replace '-([^-]+)-', '&$1&'&content&
Note the use of single quotes is essential on the replacement string so PowerShell doesn't interpret the $1 capture group.
