Thanks
This script is awesome but somewhat tough for me as I am a beginner. Is there any possibililty to add something easy to my previous code (below) to do the same thing.
Code:
cat *.txt | awk '{print $2, $4}' | sed "/#ainst\|#Time/d" > out.txt
or
cat *.txt | awk '{NR >=3 && NR <= 1002 {print $2, $4}' > out.txt
Thanks
Besides being unneeded, if you cat the files instead of letting awk open them, awk can't recover the filenames. The awk command can easily perform arithmetic calculations (such as subtracting the number of comments found); sed can't.
You said you wanted to print a portion of the file's name on each output line. You can't do that with either of the scripts above. In your scripts, neither awk nor sed have access to the filenames of the input files they are processing.
You said you wanted to delete the 1st two lines (which start with a #) from each file. Your 2nd script can't be made to do that if you keep the cat. Your 2nd script throws away the 1st two lines of the 1st file but keeps all others. It can easily throw away all lines starting with # (like my awk script did), but since you are only giving awk one input file, it can't throw away the 1st two lines of any file except the first file it is given if it is using line numbers instead of matching lines that start with a #.
You said you wanted to print the line number (not counting the comment lines) for each line in your input files. You can easily do that by using the awk script I suggested; you can't do it with either of your pipelines without making the awk portion of your pipeline look a lot more like what I suggested before.
What is it about the awk script I provided that is too tough to understand?

I am a relative new bee in scripting. I need to develop a script such that the code would iterate through each file in a source directory and append every line of the file with '|' and the corresponding file filename.
