Wondering what the best way is to extract a substring at the end of a string that you don't necessarily know the length of. Something from the middle seems a lot easier just becuase you could use something like /THIS/../END/ and done!

Say the output is something like:

This is     1234      something       123awesome123

How would you extract the substring starting at 1 and ending at wherever it ends?

Yes, use the ^ operator to tell the pattern to start at the beginning of a line, and the $ operator to end at the end of a line.

So, if you only wanted to match "The" that started at the beginning of a line:

(^The)

is a sample pattern you could use to find it.

Hope that helps.

- . will match any character (except a newline), or [^X] will match any character except X.

- * will match zero or more of whatever it follows, up to as many as are present.

Combining these two things, you can get the substring from the first 1 to the end of the line with

m/(1.*)/

or from the first 1 up to (but not including) the second 1 with

m/(1[^1]*)/
