Hi,
Im using awk to go through every line, but i have to use it twice as the first awk finds all the lines with a number in one field and the pipes it to wc, and the second does the same as the first but it has a extra pipe into sort and uniq that finds all the unique lines.
eg
awk... | wc -l
awk... | sort | uniq | wc-l
the output should be 2 lines, the frist being the numbers of lines that match the text given, and the second the number of unique lines that match the text.
is it possible to shorten this to one line as its not very efficient having to go through the whole file twice.
Thanks

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
