Why must it be sed?...

Anyway:
Code:
sed -n '/^[^,]*,,,,20090[1-4].*/p' infile
0206554475,,,,20090327,123634,85,,2,15615533
0206554475,,,,20090327,134431,554,,2,7246177
# or
awk -F"," '$5 < 20090500 {print}' infile
0206554475,,,,20090327,123634,85,,2,15615533
0206554475,,,,20090327,134431,554,,2,7246177

MAKE_SOCKSFC(8) 					      System Manager's Manual						   MAKE_SOCKSFC(8)

NAME
make_socksfc - Generates frozen configuratyion file for SOCKS clients SYNOPSIS
make_socksfc [infile [outfile] ] DESCRIPTION
make_socksfc reads in a plain-text configuration file for the SOCKS clients and produces a frozen configuration file as the output. Both arguments are optional. The default for infile is /etc/socks.conf; the default for outfile is /etc/socks.fc. You may specify infile while omitting outfile, but you cannot specify outfile without also speficying infile. The contents of the frozen configuration file is essentially the memory image of the parsed input file. Using the frozen configuration file can reduce the start-up delay of the SOCKS client programs since they no longer have to parse the file contents. When the SOCKS client starts, it always looks for the frozen configuration file /etc/socks.fc first . If that file is not found, it then tries to use the plain-text configuration file /etc/socks.conf. If you use frozen configuration, you must remember to run make_socksfc every time after you modify the plain-text file or the SOCKS clients will continue to use the frozen file of a previous configuration. To find out the contents of a frozen configuration file, use dump_socksfc. FILES
/etc/socks.fc, /etc/socks.conf SEE ALSO
