After rebooting a Sun 4/260, SunOS 4.1, I find that sometimes 'if'
statements are mysteriously mishandled in the Bourne shell.  Doing sh
-x on the scripts reveals that some if's are evaluated and then the
script dies without completing.

This leaves my machine in a fairly crippled state; does anybody have
an idea on how to fix it?  Reboots including cold starts have no
effect.

Sounds like a "set -e" has been done somewhere. This causes the shell to
quit if any command (including a test) fails (returns non-zero).

Thanks to all who responded.  One suggestion was to copy sh from the
distribution tape.  Somehow sh had a modification date of Aug 30;
copying sh from another machine fixed it.

I have no idea how it changed or what changed; # of bytes is identical
but cmp said byte # 24585 was different.

I hate mysteries.
