I have downloaded, and installed the current RFC files via zypper, into /usr/share/doc/rfc/. All my RFC files are gzipped.

When I want to find a particular topic, I use this command in my bashrc configuration file as function:

findrfc() {
  for file in /usr/share/doc/rfc/*.gz
    zcat $file|head -20|grep -i $* && stat -c "%n" $file

However, this method is a way too time consuming. Is there a more efficient way, or a program like the "apropos" command for man pages that would accomplish this task?

Did you try rfcutil?

I didn't use it myself, but that's what my packagemanager claims:

* app-text/rfcutil
     Available versions:  3.2.3 (~)3.2.3-r1
     Description:         return all related RFCs based upon a number or a search string

Update: yes, it works just fine.

valentha qdot # rfc -i
Modem users one moment, it's about 1024k (doesn't need to be updated often)
original lines  = 0     /var/cache/rfc/rfc-index
new lines       = 25078 /var/cache/rfc/rfc-index

valentha qdot # rfc -s Avian  
The Result:
1149 Standard for the transmission of IP datagrams on avian carriers.

Once again i am answering my own question

Ok the perl Script qdot suggested tries to find the words in the index file. i was not aware of the existence of such file. Therefore:

zgrep -i $* /usr/share/doc/rfc/rfc-index.txt.gz || echo "no subject found in rfc for $*"

is the command i was looking for.
