compare two files

File1
E100 0 5/29/1993 0 E001 E000
E102 0 1/23/1994 0 E001 E003
E104 0 6/4/1994 0 E001 E003
E105 0 7/30/1993 0 E001 E003
E106 0 1/9/1993 0 E001 E003
E108 0 2/3/1995 0 E001 E003
E109 0 2/15/1995 0 E001 E001

File2
E108 0 2/3/1995 0 E001 E003
E109 0 2/15/1995 0 E001 E001
E110 0 2/15/1995 0 E001 E001
E111 0 9/15/1996 0 E001 E001
E112 0 4/21/1997 0 E001 E001



These are the two files
Column 1,2 and 3 are the key fields.
A TO B MAPPING

I need to compare file1 key columns and the file2 key columns. If File1 key column matches with File2 key column move the entire row of file1 which are matching to > File3.

E108 0 2/3/1995 0 E001 E003
E109 0 2/15/1995 0 E001 E001



If the key columns of file1 not matches with file2 then move the entire row of the file1 which are not matching in the file2 > File4.

E102 0 1/23/1994 0 E001 E003
E104 0 6/4/1994 0 E001 E003

Code:
awk 'END { for (k in f2) {
    split(f2[k], t)
    print f2[k] > (((t[1] SUBSEP t[2] SUBSEP t[3]) in f1) ? "file5" : "file6")
    }
}
NR == FNR { 
f2[$1,$2,$3] = $0
next 
}
($1 SUBSEP $2 SUBSEP $3) in f2 { 
print > "file3" 
f1[$1,$2,$3] = $0 
next 
}
{ print > "file4" }
' file2 file1

Use nawk or /usr/xpg4/bin/awk on Solaris.

Or even:

Code:
awk 'END { for (k in f2) {
    split(f2[k], t)
    print f2[k] > (((t[1] SUBSEP t[2] SUBSEP t[3]) in f1) ? "file5" : "file6")
    }
}
NR == FNR { f2[$1,$2,$3] = $0; next }
{ print > (($1 SUBSEP $2 SUBSEP $3) in f2 ? "file3" : "file4")  
f1[$1,$2,$3] = $0 }' file2 file1
