Hi,
Does any one know how to avoid the scenario where awk ignores the fields having only spaces or empty fields?
for instance,
Data: "a","b","c","d",""," "
code:
awk -F, '{ print NF }' File
the output I get is 4 instead of 6 do you know how to avoid this? (6 Replies)
This seems to be a stupid basic question, but I cant get the space to stick in the awk variable.
I do use this command to grep a time range of the log file.
cat /var/log/daemon.log | awk '$0>=from&&$0<=to' from="$(date +%b" "%e" "%H:%M:%S -d -24hour)" to="$(date +%b" "%e" "%H:%M:%S)"

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
