man bash:

Quote:

[...]
OPTIONS
In addition to the single-character shell options documented in the description of
the set builtin command, bash interprets the following options when it is invoked:
[...]
SHELL BUILTIN COMMANDS
[...]
set
[...]
−n Read commands but do not execute them. This may be used to check a shell script for
syntax errors. This is ignored by interactive shells.
[...]

Remember that /bin/sh could point to a different shell than bash.
