Search Results

Yes - and no. Yes, the better you define what you want the better results you will get. No, this has nothing to do with greedyness. Greedyness is the fact that if there several possible matches for a...

Your first pattern doesn't match for two reasons, of which you found and (roughly) eliminated one (congrats!): As the pattern is anchored at begin-of-line with the ^ [/ICODE, you need to allow for...

The force flows strong in me, LOL!



Actually you came very close. What you didn't get was the part i left out in my little introduction, so here is part two:

Grouping
To combine several...

The /2 option does not work if the .* has already matched too much. For example
echo "name something name something" | sed -n 's/.*name/XXXX/p'
XXXX something
echo "name something name something"...

Very good! sed might be "love at third sight", but it is an immensely mighty tool.

Here is a very short introduction to my favourite topic:

Regular Expressions

Regular expressions are...

Exactly. The first character that matches in the trailing .* is a quote.
As I said, the leading and trailing .* are needed to "match away" the entire line. Otherwise only the matching portion would...

[^"] is a character that is not a quote
[^"]* is any consecutive number of non-quote characters
\( \) does not mean a character but is a group mark, for later reference...

As vgersh99 already noted "grep" comes from "g/re/p", which is a (schematised) sed-command. Let us see if i can help to improve your understanding:

grep is basically a line filter: you feed it a...

grep stands for 'g/re/p' of sed [where g is Global, re is RegularExpression and p is Print]

I don't think so, generally. grep is not intended nor designed to replace or remove patterns or partial strings. Be aware that sed has similar powerful matching algorithms as grep has.
In your...

local means: the variable exists only within the current scope.
In Bash: within the current function.
Bash is not a declarative language, and has loose type binding.
For example you can add a 1 to...

Another comment.
"href.*view more" works the same with ERE and RE, so egrep can be replaced by grep.
And because sed takes an RE and does not yet have one, you can move it to sed
link=$(
curl...

Even if i am not RudiC: you do quite fine.



In (german) medicine there is a proverb: who heals is right. In programming the same is true: as long as a program is doing what it is supposed to do...

If you'd accept a trailing comma (removal would need additional measures), set the output record separator to comma: ORS=",". As ALL info would come in a long line, then, we need to find out how to...

A wee bit improved so you can add the search words at the end as parameters separated by pipe symbols:


curl -s...

This may serve as a starting point (file contains the web content downloaded before):

awk '/href.*view more/ {sub (/^[^<]*<a href="/, "curl -s https://www.dotmed.com")
sub...

Please back these details up with input samples and how and where to get those! How to identify the data you need. You don't expect people in here to crawl through all those sites, do you?

Thanks for the system details. I'm not familiar with the macOS, and the bash version is somewhat aged, but you might get along.

So, now we have a text to work upon. What do you want to extract...

Welcome to the forum.

It is always beneficial to post the OS and shell version you are using as well as tools and their versions (e.g. awk, sed, ...) available.

This is not a new request; it...
