Don’t do that #21: Use multiple Replace to select numbers in a string

Don’t do that: I saw that many times, some people want to extract some numbers in a string and they use the Replace method several times.

or

$log -replace 'backup-full-', '' -replace '-disk-D', ''

It will return ‘22042015’ in this case, but I don’t like this approach because it is “too much” work and in case the prefix/suffix is changed, it does not work.

Do that: I like that one to simply match digits.

[regex]::match($log,'(\d+)').value
