So it's better to do this:

cd /whatever && somecmd

In this case, the somecmd command is only executed if the CD command was
successful. Therefore, if the directory change doesn't work, the error
message will be the one from the cd command, and the somecmd command
won't be executed.



For completeness, note that if you substitute two pipe symbols '||'
instead of the two ampersands then the subsequent command will be
executed only if the first one failed with an error. That can
occasionally come in handy.

Thus:

do this || and do this if the prior command failed.
