data base update

hello everyone
I need to update data base in file

1-ID
2-Name
3-ID group
4-ID teacher
5-mark list

unique ID is (ID+ID group+ID teacher)
we can append 5 th columns (marks list)

main base file:
Code:
Code:
1:John:3:1:4 3 2
2:Mark:1:2:1 3
3:Susan:3:4:

input file:
Code:
2:Mark:1:2:1 3 5 6
3:Susan:3:4:2 4 3

main base file after update:

Code:
1:John:3:1:4 3 2
2:Mark:1:2:1 3 5 6
3:Susan:3:4:2 4 3

I have a problem with add files to array and with compare student ID
Code:
awk 'BEGIN {x=0}{z=0}{y=0}

{getline base[x++] < "base" }

{getline input[z++] < "input" }
 
END
{for (i in base)
    for(n in input)
	if (base[i]==input[n]) //I now, it's not OK column 1,3,4 must be ==
	    output[y++]=input[n]
	else
	    output[y++]=base[i]
}	

{for (z in output)
print output[z] > "base"}'

CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
