Many thanks for your response. I tried the command with awk and nawk as below
awk 'NR == FNR {_[$1,$2] next }!(($1,$2) in _)' old new
but get an error message as
awk: syntax error near line1
awk: illegal statement near line1
nawk: syntax error at source line 1
context is
NR==FNR { _[$1,$2] >>> next <<< } ! (($1, $2) in _)
nawk: illegal statement at source line 1
Please can you tell me where i am going wrong
Yes,
in my post there is a newline before the next statement.
If you want to run it on one line, you should change the command:
Code:
awk 'NR == FNR { _[$1,$2]; next } !(($1,$2) in _)' old new

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
