Problem with update_virus_scanners script on Solaris

[Mike Brudenell]

Greetings -

MailScanner 4.23-11 includes a revised version of the
bin/update_virus_scanners script.  This appears to extract out details of
the wrapper scripts from the etc/virus.scanners.conf file.

Unfortunately on Solaris the code to do this doesn't work.  In particular
this section of code:

    cat ${SCANNERSCONF} | sed -e 's/#.*$//' | fgrep -e -wrapper | \
    while read NAME WRAPPER PACKAGEDIR
    do
        ...

assumes 'grep' can take a '-e' option (to, I suspect, signal the next item
is a pattern despite it beginning with a '-' character).

The standard grep (/usr/bin/grep) on Solaris doesn't have such an option,
and so the script fails.

Two possible solutions:
 a) Change to use 'fgrep' instead of 'grep', or
 b) Change to use '/usr/xpg4/bin/grep' instead

Of the two I'd suggest (a) is likely to be more cross-platform friendly ...
unless of course you know differently?

Cheers,

Mike Brudenell
