Regular expression: how to deal with character /

Question

I’m using grafana to get zabbix agent data.

I need to match only one of these following values:

Free space on C: (Percentage)

Free Space on / (Percentage)

This expression doesn’t let match the second one:

/^(Free space on C: (Percentage)|Free Space on \/ (Percentage))$/

Even in online regex text doesn’t match as well.

I’m pretty sure the problem is with the character /.

Shouldn't match any of them. You'll have to escape the parentheses. [Check this](https://regex101.com/r/554v7v/1) — SamWhan, Apr 24 '18 at 12:05

What about if you escape the forward slash with a forward slash, like this?

/^(Free space on C: (Percentage)|Free Space on // (Percentage))$/

Try this:

/^Free [Ss]pace on (?:C:|\/) \(Percentage\)$/gm

To match one of your values you have to escape \ the parenthesis around (Percentage)

If you only want to match your values might use a non capturing group ^(?:
