I recently came across the following example for switching time zones:
$ date
Fr 6. Jun 12:49:30 CEST 2008
$ TZ=UTC date
Fr 6. Jun 10:49:35 UTC 2008
Could someone please explain to me the general shell syntax involved here? I
did not know that I could put an assignment and a command on one line. My dull
approach would have been
$ echo $TZ
$ TZ=UTC
$ export TZ
$ date
Fr 6. Jun 10:54:29 UTC 2008
$ unset TZ
$ date
Fr 6. Jun 12:54:39 CEST 2008
Thanks in advance,
Malte
