may not be dumb so much as uncuddled...unless there's a reverse typo it looks like you'd be able to achieve it once you properly wrap the inline function:

You'd posted:

Code:
size=`cat ramfs_size`
linux_size=`awk -F'=' '/DEV_RAM_SIZE/ {print $2}' .config
sed -i 's/$linux_size/$size/g' .config

Did you mean to say:

Code:
size=`cat ramfs_size`
linux_size=`awk -F'=' '/DEV_RAM_SIZE/ {print $2}' .config `
sed -i 's/$linux_size/$size/g' .config

Better yet:

Code:
size=$(cat ramfs_size)
linux_size=$(awk -F'=' '/DEV_RAM_SIZE/ {print $2}' .config )
sed -i 's/$linux_size/$size/g' .config

Whatever works, works, but backticks are too easily mistaken for nonsense...or left out...
