Correcting awk error

the following code turns back ticks "`" to new lines "\n". Then, it attempts to grab only a certain section of the output and excludes lines that contain particular patterns...i.e. "ZooLine|echo|opencert".

Code:
awk -vs1="\`" '{gsub(s1,"\n",$0)} 1 {print ; if(/NewLine \(\)/,/}/{if(!/NewLine|echo |openssl/) print} END { print }' datafile

however when i run this, it fails with:

Code:
awk: cmd. line:1: {gsub(s1,"\n",$0)} 1 {print ; if(/ZooLine \(\)/,/}/{if(!/ZooLine|echo |opencert/) print} END { print }
awk: cmd. line:1:                                                ^ syntax error
awk: cmd. line:1: {gsub(s1,"\n",$0)} 1 {print ; if(/ZooLine \(\)/,/}/{if(!/ZooLine|echo |opencert/) print} END { print }
awk: cmd. line:1:                                                                                         ^ syntax error
awk: cmd. line:1: {gsub(s1,"\n",$0)} 1 {print ; if(/ZooLine \(\)/,/}/{if(!/ZooLine|echo |opencert/) print} END { print }
awk: cmd. line:1:                                                                                                      ^ unexpected newline or end of string

This is an invalid program and without formatting it's hard to guess what you are trying to achieve. Can you explain what you are attempting to do with this statement:

Code:
1 {print ; if(/ZooLine \(\)/,/}

Particularly, where is the ) for this if statement?

i think, error is here :
Code:
1 {print ; if(/NewLine \(\)/,/}/{

Also, what is the use of / marked above in red ?

I would suggest that you stop trying to write 1-liners that you (and awk) can't parse.

If you write readable code, you'll much more easily see that there are mismatched braces and mismatched parentheses.

But since none of your three code samples seems to be trying to do what you said this script is supposed to do (the code seems to be trying to print every line once, print some lines twice, and maybe print the last line three times, and the strings being searched for do not match the strings in your description, and there is no mention of looking for Newline () or looking for Zooline ()), I can't guess at how to fix the syntax errors to get what you might be trying to do. And, with no sample input and no corresponding desired output, I have no idea where to start.

Sorry, but I'm lost.
