Yes but ONLY if /bin is the first location it finds "sh" in as determined by PATH.
The PATH variable determines locations to search. So if you do "echo $PATH" and it shows "/bin:/usr/bin:/home/myhome" and you search for "sh" it will will find /bin/sh first and use it even if /usr/bin/sh and /home/myhome/sh exist.
If however you had "/usr/bin:/bin:/home/myhome" in PATH it would find the one in /usr/bin first and ignore the one in /bin.
Of course if you type "/bin/sh" that is an absolute reference and it would ignore PATH.
Also, some utilities like bash and busybox will look at how it was called and alter its behavior as necessary. For example, if you symlink /bin/bash to /bin/sh and then call /bin/sh, while /bin/bash is the executable that's ultimately being run, it very well might see that you called it as "/bin/sh" and alter its behavior to reflect sh's limited command set.

Thank you both, that helps a lot.
