Top Forums UNIX for Dummies Questions & Answers How to count lines - ignoring blank lines and commented lines Post 302118832 by kthatch on Thursday 24th of May 2007 12:03:54 PM
Old 05-24-2007
I tried each of these suggestions and neither worked.

Results:

#egrep -cv '#|^$' active_servers
this displayed the total but on screen only, not in the file

#awk '!/^#/ && !/^$/{c++}END{print c}' active_servers
same as above

#awk '!/^[ \t]*(#|$)/ {c++; ct++} /#/ && c { printf "%s\n\n\n%s", c, $0; c=0} END { print ct}' active_servers
awk: syntax error near line 1
awk: bailing out near line 1

To provide more detail, I have a script that produces the output above (in my original post) to a file - less the totals that I am seeking help with. When I refer to comments, I mean lines that are preceded with ## and the sections are separated with a blank line as a result of this "sed '/this/{x;p;x;}'" in my script.

Thanks again! More suggestions would be welcome!

igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION

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
