I didn't write the following regex, and I'm trying to figure out what it does. I know that it must begin with policy-map and must have at least one space between policy-map and whatever comes next. But I'm stuck trying to figure out what the stuff inside the parenthesis means. I know that whatever it is, it has to be at the end of the line.
^policy-map\\s+([\\x21-\\x7e]{1,40})$
Thanks!
characters in range from hex 21 to hex 7e (basically printable, non-whitespace ascii) 1 to 40 times.
[\\x21-\\x7e] is commonly used to describe alphanumeric+special chars
^ begin of string
policy-map constant
\s+ spaces
([\x21-\x7e]{1,40}) 1-40 symbols from \x21 to \x7e (i.e. all printable, non-whitespace ASCII characters including punctuation, upper and lower case letters and numbers)
$ end of string
^ Start of string
policy-map "policy-map"
\\s+ One or more whitespace characters
( Start of capture group 1
[\\x21-\\x7e] From 1 to 40 characters in the range '\x21' to '\7E'
) End of capture group 1
$ End of string
