You can validate that you are running dash by adding the command
ps | grep $$
The $$
variable contains the PID
of the process of the running shell.
Question
I want to execute some scripts on dash shell compared to standard default bash. This is an example (test.sh)
#!/bin/dash
echo $SHELL
echo $0
This execution gives me
/bin/bash
./test.sh
as output. I was expecting '/bin/dash' as output.
If this is wrong, can someone let me know how do I actually work on dash. Thanks

OTHER TIPS
SHELL
environment variable picks up the value from /etc/passwd
. (It denotes the path to user's preferred command language interpreter.)
This value wouldn't change if you change the shell in your session or your script.
This one would show the exact command.
ps o command --no-header --pid "$$"
