In this course I'm watching, I have the following example, which works as expected:
Code:
grep -Po '(ID|(?<fn>Function)|(?<dur>Duration)): (?(fn)\w+?\.\w+|(?(dur)\d+\.\d+ ms|\w+))' high20.txt
ID: php_install
Function: pkg.installed
Duration: 587.977 ms
ID: mod_mysql
Function: pkg.installed
Duration: 14.708 ms
But whenever I try this:
Code:
grep -Po '(ID|(?<fn>Function)|(?<comm>Comment)): (?(fn)\w+?\.\w+|(?(comm)\w+?\s\w+)|\w+))' high20.txt
I get the following error:
Code:
grep: conditional group contains more than two branches
Which really intrigues me, because the only significant difference I can see is the naming convention that I attribute to the regex ("comm" instead of "dur" and the regex itself which is only slightly difference, but I'd say there shouldn't make any difference to the syntax itself). Any ideas what's going on?
Never mind - an additional unnecessary paranthesis. Only after I posted it did I see it. I couldn't perceive it as such in the command line.
So instead of \s\w+)| it should have been \s\w+|
