What have you tried to solve this problem on your own?
still in early stages of awk so nothing I got on this
What is a "stripped one column string"?
Sorry if that was confusing but what I was trying to say it to print the line with few columns which are consistent(first and last 3 columns) and along with that in between data to be cut/stripped and print data that is lying between () brackets.
Is it crucial that the varying numbers of spaces between the various columns in the input be duplicated in the output?
Yes, as I said above, I need first and last 3 columns and the string mentioned inside () only as rest all doesn't make any sense to me and it sometimes goes too lengthy..
What, exactly, does "the column for string between brackets() are dynamic" mean? Will there ever be more than one pair of parentheses on an input line?
using the dynamic means the number of columns between first and last 3 columns are unpredictable as it's kind of description for developers but meaningless long data to me.
It'll be helpful If I can have single line command so that I can pipe to the output and get the desired results.
Again sorry for the confusion if any.
I fail to understand how changing varying numbers of <space>s between fields in your input lines (such as 1 <space> between most fields, but 2 <spaces> between the 1st and 2nd fields in the 2nd input line in your file) into single <space>s between fields would make it hard for you to identify the first three fields or the last three fields in the output you're trying to produce. This is especially confusing since the output that you say is needed for the 2nd line from your input file must create output that has 2 <space>s before the last three fields in the output when there was only 1 <space> in that position in your sample input file??? Insisting on this requirement does invalidate everything that drysdalk suggested. But, I don't understand how requiring additional <space>s in the output helps keep the output from being "too lengthy".
Please clearly explain why changing 2 <space>s between the 1st two fields in your sample input to 1 <space> between those fields in the output would make it hard for you to determine the data in those fields. And, please clearly explain why additional <space>s need to be added between some output fields when they were not present in your input file? (I.e., describe the logic that determines when additional <space>s need to be added!)
The number of lines in an
awk script has absolutely no effect on whether or not you can pipe data into that script or pipe data out of that script. The only reason to insist on a one line
awk script is to make it harder to read (especially for someone who is learning how to use
awk or who is using a screen that doesn't wrap long lines of code). Our purpose on this site is to help people learn how to use the tools that are available to them on the systems they're using. Writing obfuscated or otherwise unreadable code does not help us achieve that goal.
Please either remove this requirement or make a MUCH more convincing argument as to why you need a one line solution!
P.S. And please answer the question I asked in post #3:

If the answer to this question is "Yes" there might not be any way to achieve your goal.
