Re: Regex question

in reply to Regex question

There are a few points you need to learn about the s/// operator:

The first part (right after "s/") is called the pattern -- that is what you expect to match in the input string.
The second part (after "s/pattern/") is called the replacement -- that is what gets put in place of the pattern.
The value returned by "s/pattern/replace/", is always "1" for true if the pattern matched and was replaced, and "0" for false if it didn't match.

You gave a couple examples of input, but it's not at all clear what you wanted for output. Could you explain a little more about that?

Thanks for all your help so far, really appreciated. I need to clarify a little..... There are many iterations (hundreds) of points and levels that I need to write to another file, and they are all different, for example; points: "{lbzAb{pnCedn@_t{S", levels: "PP", points: "abetBivqgFwtcOv `Ayspb@lhiVopoFxzmEysmBl\|s@gv`Bd`M", levels: "POMMLP", I need a way of copying the lines containing the values for points and levels (however long the strings are) to the new file. I am now thinking that the substitution operator is not the right one. My output is therefore the same as the input, in that the script searches the input file for all iterations of: points: "variable_length_string_containing_any_characters", levels: "variable_length_string_containing_any_characters", And simply writes this to another file..Do I need a loop to achieve this?
