Hey, I'm doing similarly heavy neccessary I/O operations

the thing with putting it into a variable, is you lose the carriage returns. Thats the only problem I can see, it's a bit messy too. You could substitute carriage returns with an unused character such as (�) and translate them later,.

i.e filevarsub=$(echo $somefiledata | tr -t "\n" "�")

then bring it back to write to the final file output

echo $filevarsub | tr -t "�" "\n"

simple, but inelegant.

secondly, you could mount a ramdisk,

mkdir ram # in your main scripts directory
sudo mount -t ramfs /dev/ram ram #there are no options for ram, so umask etc doesnt work
sudo chown $USER ram #i$USER is who you're logged in as

you could stick it /etc/fstab to automount on boot just for your scripts,
or you could fix it so that mounting doesn't require root permissions (be careful with that one), so you can mount from within the scripts

I'd love for there to be a better way, if anyone knows please do tell
