That is correct. Thanks. As I said before, I did expect adding the extra \ would work, was surprised it did not. I just copied the posted script verbatim, did not see the extra semicolon. Here is the...

That's for sending the exact input file and script you are using. That really helped.

I took another look, tried several things, learned it's a sticky wicket, found something that seems to work...

awk 'NF && !/#/ {action}' file

First, it would need to be !/^#/ to mean "do not act on lines that start with #".

Second, the idea was to act on lines...

The pattern within /PAT/ cannot include variables. The spacebar fixed pattern is one solution. A more general solution, exactly the way you want it, is as follows:
PAT=X "(15|20|45|70)" Y; if (Z !~...

awk '/^[^#]/ {print}' file


It prints lines that start with a character that is not #. A blank line does not start with a character. So a blank line is not printed, so the blank line is removed...

I read it as "n == 3". But you're right, it's not really clear.

If the intent is "n >= 3", then you either:
- Use the scrutinizer shorter solution designed for "n >= 3", or
- Change == 3 to >=...

You pass variables from a.sh to b.sh by adding the variable after the script name, such as b.sh "$x". You receive variables in b.sh by using $1 for the first variable passed, $2 for the second, etc....

The * is messing things up:

You could use \* instead of * for Str1, similarly escape other metacharacters as needed. I know that's a bother, but certainly doable. Not sure what else to suggest that would work.

I'm not sure what the hadoop command is doing. Anyway, maybe this might work:
