The data that you have in your text file and the commands you are using to extract data from that text file do not seem well suited to what you are trying to do. Please create a file named test.txt that contains the following text:

Code:

f1|f2|f3|f4|f5|f6|f7
field 1|field 2|field 3|field 4|field 5|field 6|field 7
3: It was really a good fun in doing so.
4: Really good.| (Here i am using pipe)

After creating that file, what output do you get when you run the command:

Code:

cut -d '|' -f2 test.txt

What output do you get when you run the command:

Code:

cut -d '|' -s -f2 test.txt

What output do you get when you run the command:

Code:

cut -d '|' -f2,4-6 test.txt

After running these commands do you understand what I meant about the 6 vertical bars (AKA pipe symbols)? Do you see that the cut commands in your script are extracting data from 7 pipe symbol delimited fields from lines in the input you feed into it, but only two of those lines contain any pipe symbols?

Have you read the manual page for cut on your system? If not enter the command:

Code:

man cut

and look at how it describes the -d, -f, and -soptions. I know that you aren't using the -s option in your code, but (with the possible exception of when you are extracting field 1 data) you might want to consider it. Do you understand now what I meant when I said "you are trying to extract data from seven vertical bar separated fields in your input file"?
