Question 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

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 BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
