Are you sure about the flat-file approach? That way you
always have to read/write the whole thing when editing a
single item like:
#!/usr/bin/perl -i
#first arg is the item_number, second the text-file with replacement
#dbase file on STDIN, edited file on STDOUT
my $item_number = $ARGV[0];
open IN, $ARGV[1] or die "Could not open $ARGV[1]: $!";
my $replacement;
{
local $/ = undef;
$replacement = <IN>;
}
{
local $/ = '::';
while( <> ) {
$_ = $replacement if $. == $item_number;
print;
print '::' if not eof;
}
}
When the dbase gets large, the overhead may become
problematic. Consider a RDBM like
postgres
or a
good DB like BerkeleyDB.
