And can u pls expain simply how code is working ??
Yes.
It's an AWK script:
var=value assigns a value to a variable var accessible inside the AWK code.
So id=123 is the desired id to be passed to the program.
Following the code logic we have:
1. Construct the logical record (r) by concatenating all the records seen so far:
record r -> if record is not empty: r ? -> add a record separator (RS, newline by default) and the current record ($0): r RS $0, else (record is empty, it's the first access -> assign the value of the current record: : $0
This is the meaning of the following expression:
2. Check if the current record matches the pattern "cm:" followed by the value of the variable id (see above): $0 ~ "cm:" id. If the test returns true, auto increment the value of the variable f (f for flag, marker): { f++ }.
3. If the current record does not match the pattern ^[\t ] : the line does not begin with a blank character (tab or space), these are your E, D etc records, do the following:
- check if the value of the variable f in Boolean context returns true (is not an empty string or has a numeric value 0): if it's true (not 0, see 2. above), this logical record contains our id, so we print it: print r.
- reset the r and the f variables, we will initialize them after if needed.
4. After reading the entire input check if we have something to print.
This is because of the build (r) -> set (f) -> check after (!/^[\t ]/) logic:
we print the previous when we reach the current. So without the END block we may miss the last one.

If I have a string that has some name followed by an ID#(ex.B123456) followed by some more #'s and/or letters, would it be possible to just grab the ID portion of this string? If so how? I am pretty new with these text tools so any help is appreciated.
Example:
"Name_One-B123456A-12348A" (2 Replies)

I don't necessary have a problem, as I have a solution. It is just that there may be a better solution.
GOAL: Part one: Parse data from a file using the "\" as a delimiter and extracting only the last delimiter. Part two: Parse same file and extract everything but the last delimited item.

I'm new to shell programming, but I think I learn best by following an example. I'm trying to cook up an awk/sed script, but I obviously lack the required syntax skills to achieve it. The output that I get from running my ksh script looks like this:
