Can you tell me how this, using host and ip gets the column information.
i.e. suppose there was more columns?
Thanks for the fast reply
Excerption from the man page of sh:
Quote:
read [-p prompt] [-r] variable [...]
The prompt is printed if the -p option is specified and the stan-
dard input is a terminal. Then a line is read from the standard
input. The trailing newline is deleted from the line and the line
is split as described in the section on word splitting above, and
the pieces are assigned to the variables in order. At least one
variable must be specified. If there are more pieces than vari-
ables, the remaining pieces (along with the characters in IFS that
separated them) are assigned to the last variable. If there are
more variables than pieces, the remaining variables are assigned
the null string. The read builtin will indicate success unless
EOF is encountered on input, in which case failure is returned.
By default, unless the -r option is specified, the backslash "\"
acts as an escape character, causing the following character to be
treated literally. If a backslash is followed by a newline, the
backslash and the newline will be deleted.

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