problem in sorting data's in chronological order

[ade]

Hi, am new on this forum could any one please help me out with these. I tried sorting out data sets of packet field header for anomaly detection system using the command
./phad0 700 in3* |sort +0.45 -r >phad1.sim

but i got the error message

sort: open failed: +0.45: no such file or directory

and then decided to creat a directory for +0.45 and re-ran the command, i got another error message saying sort:read failed: +0.45 is a directory

thank u.

That's not really a C++ question now, is it? Have you tried man sort?

thank u,
hve tried it, but it did not work got the error message: No manual entry for +0.45 and r.

Actually the phad0 is the compiled souce code of phad written in C++, compiled on gcc g++ while the phad1.sim is the file extension for phad0 and in3* is the tcpdump files that i want to sort in chronological order from in31 t0 in37.
