awk - end of line - Help!
I have a textfile which I am parsing with awk. The lines do not have the same number of fields, so sometimes $3 is the last field, sometimes not.
When I do a 'printf("%s, %s\n", $2, $3)', if $3 is the last field in the line, when I cat the file the output looks something like this:
,someemail@someprovider.com
If I 'vi' the file it looks like this:
NAME^M^M,someemail@someprovider.com
Oh, and the textfile is a DOS file ported over to Unix. How can I get rid of those two newlines where $3 is the last field?

However this clears the spaces in... (6 Replies)

Hi,
I have data with approximately 300 columns.
I want to add a column to the end of each column with the value "1".
Is there a way that I can do this is ´awk´ without having to specify each individual column.
For instance, my data looks like:
pvb 1 2 3 4 5 ....... 300
fdh 3 4 5 2 4 ......... (4 Replies)

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