In Dash, echo flags besides -n are not supported.
Problematic code:
#!/bin/dashecho -e "Name:\t$USER"
Correct code:
#!/bin/dashprintf'Name:\t%s\n'"$USER"
Rationale:
Your script uses a shell feature not supported by the shebang. Either rewrite the script to be portable, or change the shebang to explicitly require a shell like Bash.
In this case, you can rewrite your use of echo using printf, which behaves the same across shells.
Exceptions:
None
