How to get output of URL (RegExp) A.K.A Regular Expression

Onion master · 04-14-2014, 10:01 AM

So i have found a set of regular expression i can use to grab all data, how do i make it output into .txt files in the server or into some other way so i can lookup the data.

Here is how my URL (RegExp) looks like: /(([A-Za-z]{3,9})://)?([-;:&=\+\$,\w]+@{1})?(([-A-Za-z0-9]+\.)+[A-Za-z]{2,3})(:\d+)?((/[-\+~%/\.\w]+)?/?([&?][-\+=&;%@\.\w]+)?(#[\w]+)?)?/g

How do i output this into either .txt* files names after each PC who uses it or into a server?

Thanks.

not really following but to redirect any output to a file you use for e.g.:

Code:

ls -l > overwrite-file.txt
ls -l >> append-file.txt

Thanks so i add that to the end of my RegExp and make it look like this: /(([A-Za-z]{3,9})://)?([-;:&=\+\$,\w]+@{1})?(([-A-Za-z0-9]+\.)+[A-Za-z]{2,3})(:\d+)?((/[-\+~%/\.\w]+)?/?([&?][-\+=&;%@\.\w]+)?(#[\w]+)?)?/g/ls -l > overwrite-file.txt
ls -l >> append-file.txt

Is that correct? i space it with / if i remember correctly.

The point of this RegExp is to grab all input from browsers and so on from my customers, and i wish for it to output a personanme.txt to each person
So i can grab the data from FTP later on.

Basically every person's data to be outputted into his very own .txt file.

please give a sample input and a sample output and maybe we can provide some advice.

A regex by itself won't do anything. You need to give it to an program (or application or executable) to apply it to your data. The three most likely programs you might use it with are sed, awk and perl. (grep also uses regexes, but that doesn't look like it's for grep.)

Do you know which one you're using?

Also, the trailing g puzzles me. I've only used it in substitutions, s///g, not matches. But perlop says, "The /g modifier specifies global pattern matching--that is, matching as many times as possible within the string. How it behaves depends on the context. ..."

But are you expecting really long lines with multiple matches per line?
