Hello,
Between pattern1 and pattern2, I'd like to do a substitution. I got it to work so that it prints to change to stdout, but it won't do the in-place edit of the file.
Here is my script so far:

#!/usr/bin/perl

#print "ARGV:", $#ARGV;
if ($#ARGV == 2 ) {
  my $host = $ARGV[0];
  my $fn = $ARGV[1];
  my $value = $ARGV[2];
  #print "INPUTS: host:$host, fn:$fn, value:$value\n\n";
  $systemsconfig = '/usr/local/etc/system.ini';
  system("cp $systemsconfig /tmp/reconfig");
  open CONFIG, "+< $systemsconfig" or die "Couldn't open $systemsconfi
+g";
  $^I = ".bak";
  while (<CONFIG>) {
        if ( $_ =~ m/^\[$host\]/ .. m/#END/ ) {
          $_ =~ s/$fn=(.*)/$fn=$value/;
          print;   # i thought print CONFIG here???
        }
  }
  close CONFIG;
}

Here is an example of the file that needs to be edited:

[bdstest]
MainFunction=
SystemType=U5
Env=
Location=
Serial=FW0094810719
Hostid=80c0dc14
OS=Solaris
Version=8
Disk=1x8
Memory=128
CPU=1x360
qfe=
SCSI=
GraphACC=
SupportContract=
#END


[custard]
MainFunction=
SystemType=U5
Env=
Location=
Serial=FW00250126
Hostid=80c0aee2
OS=Solaris
Version=8
Disk=1x8
Memory=256
CPU=1x360
qfe=
SCSI=
GraphACC=
SupportContract=
#END

[download]

EXAMPLE: I'd like to edit the MainFuntion= line between bdstest and #END

So I call the script like this:

/usr/local/etc/test.pl bdstest MainFunction oracle

The system.ini file is in that format because this function will become part of a perl mod I'm slowly building to use it to integrate with some bash scripts to allow people to check out configuration information (I use Config::IniFiles)

Thanks for any help!
