That will not work, since then all every time all lines that are not equal to the search string, will get printed.. You would need to test grep's return code and print "$line" if it is non-zero...

The sed command will not work because of the / delimiter, the is also contained in the files so that breaks the command... You would need to use another delimiter..

try:
Code:
awk 'NR==FNR{A[$1]; next} !($2 in A)' file1 file2

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 SEE ALSO
