I'm more of a Perl man, so here it is in perl:
put the above code in a file called something like lineExtract.pl, make it executable, then you can do the following to use it:
./lineExtract.pl <big_file_to_process
$c will contain the information one line at a time!
1 . Thanks everyone who read the post first.
2 . I have a log file which size is 143M , I can not use vi open it .I can not use xedit open it too.
How to view it ?

Hi,
I am using Sun Solaris 5.9 OS. I have found a file called wtmpx having a size of 5.0 GB. I want to clear this file using :>/var/adm/wtmpx. My query is, would it cause any problem to the running live system.
Could anyone suggest the best method to clear the file without causing problem to... (6 Replies)
Hi
I have two files, one is 1.6 GB. I would like to add one extra column of information to the large file at a specific location (after its 2nd column).
For example:
File 1 has two columns more than 1000 rows like this
MM009987 1
File 2 looks like this
MM00098 MM00076 3 4 2 4 2... (1 Reply)
We got data that was supposed to be CSV, but was sent in a huge XML file.
I've downloaded xmlstarlet, but I'm darned if I can get it to operate the "sel" feature to look down a path and get any sort of value. I see pieces of what should be paths, but they seem to have extraneous characters, and... (7 Replies)
Hello Friends,
I have a big file that is transferred to my UNIX system and it seems it has CR as the line delimiter
When I run
file <filename>
<filename>: ASCII text, with CR line terminators
How do I convert the file to one with LF as terminators so that my code that runs on UNIX can... (3 Replies)

PERLCC(1) Perl Programmers Reference Guide PERLCC(1)NAME
perlcc - generate executables from Perl programs
SYNOPSIS
$ perlcc hello # Compiles into executable 'a.out'
$ perlcc -o hello hello.pl # Compiles into executable 'hello'
$ perlcc -O file # Compiles using the optimised C backend
$ perlcc -B file # Compiles using the bytecode backend
$ perlcc -c file # Creates a C file, 'file.c'
$ perlcc -S -o hello file # Creates a C file, 'file.c',
# then compiles it to executable 'hello'
$ perlcc -c out.c file # Creates a C file, 'out.c' from 'file'
$ perlcc -e 'print q//' # Compiles a one-liner into 'a.out'
$ perlcc -c -e 'print q//' # Creates a C file 'a.out.c'
$ perlcc -I /foo hello # extra headers (notice the space after -I)
$ perlcc -L /foo hello # extra libraries (notice the space after -L)
$ perlcc -r hello # compiles 'hello' into 'a.out', runs 'a.out'.
$ perlcc -r hello a b c # compiles 'hello' into 'a.out', runs 'a.out'.
# with arguments 'a b c'
$ perlcc hello -log c # compiles 'hello' into 'a.out' logs compile
# log into 'c'.
DESCRIPTION
perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either
create executable Perl bytecode, using the "-B" option, or generate and compile C files using the standard and 'optimised' C backends.
The code generated in this way is not guaranteed to work. The whole codegen suite ("perlcc" included) should be considered very experimen-
tal. Use for production purposes is strongly discouraged.
OPTIONS -Llibrary directories
Adds the given directories to the library search path when C code is passed to your C compiler.
-Iinclude directories
Adds the given directories to the include file search path when C code is passed to your C compiler; when using the Perl bytecode
option, adds the given directories to Perl's include path.
-o output file name
Specifies the file name for the final compiled executable.
-c C file name
Create C code only; do not compile to a standalone binary.
-e perl code
Compile a one-liner, much the same as "perl -e '...'"
-S Do not delete generated C code after compilation.
-B Use the Perl bytecode code generator.
-O Use the 'optimised' C code generator. This is more experimental than everything else put together, and the code created is not guaran-
teed to compile in finite time and memory, or indeed, at all.
-v Increase verbosity of output; can be repeated for more verbose output.
-r Run the resulting compiled script after compiling it.
-log
Log the output of compiling to a file rather than to stdout.
