if you don't have the -i option on sed use PERL code below:

perl  -i -wlpe 's/TRASH_MAX_SIZE:1024/TRASH_MAX_SIZE:2040/;' config.ini

Hi Amman,

I dont use perl single liners at all. Could you tell me what the -i and the -w1pe options are??

Here you will find descriptions of all the options: perlrun - how to execute the Perl interpreter - Perldoc Browser
BTW, its "l" (lower case "L"), not "1".
