I suppose you're using (t)csh.
You shouldn't Smilie
Anyway, this may work:

Code:
awk '\!x[$1]++' file1 file2>file3

Quote:
sort works only if the file has numbers with same digits:
I mean it will sort like this
1
2
21
23
3
4
45
And not in exact manner like 1 2 3 4 21 23 45
Just tell sort to thread them as numbers
(use the -n option):

Code:
$ sort <<<'20
3
1'
1
20
3

$ sort -n <<<'20
3
1'
1
3
20

And this command. Did not work or I may not have used properly.
This is how I used :
$ <file1.dat uniq file2.dat > file3
$ more file1.dat
2 8 7 1 3 6 4 9 5 5 4 3 2 1 2 4 2
$ more file2.dat
1 2 4 3 5 6 7 8 12 11 13 14 45 56 23 0 1
$ more file3
1 2 4 3 5 6 7 8 12 11 13 14 45 56 23 0 1
[...]
Yes, I corrected my previous post: to get the output you want from uniq, the input should be sorted.

SC_WARTS2PCAP(1)					    BSD General Commands Manual 					  SC_WARTS2PCAP(1)

NAME
sc_warts2pcap -- write packets included in warts object to a pcap file. SYNOPSIS
sc_warts2pcap [-o outfile] [-s sort] [file ...] DESCRIPTION
The sc_warts2pcap utility provides the ability to extract packets embedded in the tbit, sting, and sniff warts objects and write them to a pcap file, which can be read by tcpdump and wireshark. The options are as follows: -o outfile specifies the name of the output file. If no output file is specified, it will be written to the standard output, provided that it is not a tty. -o sort specifies how the pcap records (packets) are sorted before being written out. By default, no sorting is applied; the packets are grouped as they are in the warts file. If packet sorting is specified, the packets are written out in timestamp order. Note that this operation requires the packets to be read into memory to be sorted, so it will require a corresponding amount of memory to com- plete. EXAMPLES
The command: sc_warts2pcap -o output.pcap file1.warts file2.warts will read the packet objects from file1.warts, and then file2.warts, and write them to output.pcap. The command: gzcat file1.warts.gz | sc_warts2pcap -s packet >file1.pcap will read the contents of the uncompressed warts file supplied on stdin, sort the packets by their timestamp, and then write the output to file1.pcap.
