New question
Thanks Vino,
I have another question.
Could someone tell me how to delete a string from a line in a specific position using sed or other editors which doesn't require files to be opened?
e.g. I have a file called myfile.txt which contains three lines of text below and I want all of the lines to have 5 characters or less.
1234567
a b c d e
098
I want the result to be like below:
12345
a b c
098
Any help will be appreciated.
BTW please let me know if you have any recommended sites for learning unix commands such as above.
Cheers
Steve

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...

DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
