Shell Programming and Scripting

@ ahamed101 :

The code is now working, thank you very much. But I have some other doubts whch I would like to clarify with you.!

1.
I am running this on Fedora 14, when I gave this command it said :

Code:

bash: cacm dataset/cacm.all: Permission denied

This file is located on a removable NTFS Partition of my hard drive. Then I tried to change the permissions of the file by giving the following command

Code:

chmod 644 cacm\ dataset/cacm.all

But the permissions of the file do not change,even if I try as super user the permissions stay the same. then I coped the file to home directory and with the old permissions, it worked. is there any way to get around this? Or do we need to copy the file to the Linux Partitions and then only work on it??

2.
Some of the content in the .T tag , dot not end at a line, for eg. there is this one:-

Code:

.T
The Problem of Programming Communication with
Changing Machines A Proposed Solution-Part 2
.B

So is it possible to copy multiple lines.. that is from the starting of .T tag to the starting of the next tag .B??

3.
The script you have given me has a lot of AWK scripting. I am not a very good at shell scripts. I thought of doing the job first with C , but then realized that shell script would be faster. Tried with Grep first, but realized that Grep is not very powerful and will not take me very far. I know very litttle AWK . Could you please tell me from where I can learn more??

1. Not sure

2.

Code:

awk '/^\.I/{_2="file"$2".txt"}/^\.T/{print $0>>_2;while(getline != /.B/){print $0>>_2}}/^\.N/{x=$0;getline;print x"\n"$0>>_2}' infile
