The civilized way of doing this would be: strings $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora>$ORACLE_HOME/dbs/init$ORACLE_SID.ora It gives results like:
[root_at_tux925 root]# su - oracle
-bash-2.05b$ cd $ORACLE_HOME/dbs
-bash-2.05b$ strings spfile$ORACLE_SID.ora|head -10
*.aq_tm_processes=1
*.background_dump_dest='/pub/oracle/admin/CMPL/bdump'
*.compatible='9.2.0.0.0'
*.control_files='/data1/CMPL/ctl/control01.ctl','/data2/CMPL/ctl/control02.ctl','/data3/CMPL/ctl/control03.ctl'
*.core_dump_dest='/pub/oracle/admin/CMPL/cdump'
*.db_block_size=8192
*.db_cache_advice='OFF'
*.db_cache_size=402653184
*.db_domain='wangtrading.com'
*.db_file_multiblock_read_count=32

That asterisk in front of the parameter means "for all available instances". I have only one instance, but it will still work. To make Jared's heart beat faster, this also works:

#!/usr/bin/perl -w
use strict;
my $HOME=$ENV{"ORACLE_HOME"};
my $SID=$ENV{"ORACLE_SID"};
die "Please check your Oracle environment vars!\n" if (!defined $HOME or !defined $SID); my $file="$HOME/dbs/spfile$SID.ora";
open (IN,"<",$file) or die "Cannot open $file:$!\n"; while (<IN>) {
  print $_ if ( $_ =~ /^\*\./) ;
}

That is, essentially, the same as:

egrep --binary-files=text "^\*\." $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora
