Using dash instead of bash
From Unixshell# community wiki
dash is a shell that uses much less memory than bash. To use dash first install it and then symlink /bin/sh to /bin/dash.
About dash, though it can be faster, you have to be careful.
If you make it your default shell, some scripts that depend on bash's echo may start failing.
bash:
$ echo "testing\n1...2...3..." testing\n1...2...3... $ echo -e "testing\n1...2...3..." testing 1...2...3...
dash:
$ echo "testing\n1...2...3..." testing 1...2...3... $ echo -e "testing\n1...2...3..." -e testing 1...2...3...
Users have reported freeing up to 12MB of RAM by switching to dash.
