Here's the same solution as oombera's though written in a more awk-like and less C-like fashion. Note that I'm also changing the problem somewhat: This will trim trailing lines consisting only of blanks and tabs (i.e., apparently empty) as well as truly empty lines:
Invoke it the same way as oombera's code. If you want only the truly empty lines to be whacked off the end, just change the first test to length == 0.
I am attempting to delete blank lines in my file and I've used this command:
sed '/^$/d' $file > $file.fixed
all this seems to do is copy the file and not delete the blank lines located at the end of the file. Any assistance would be greatly appreciated. (3 Replies)

Eg:

Baby Boy Kim 1234
Baby Boy Vik 1334

Baby Boy Kim 1234
Baby Boy Vik 1334

@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.

...
}
