@woolmilkporc:This is run in tcsh shell.Is tcsh shell obsolete?
No, tcsh is not at all obsolete.
csh is rather old and a bit inconvenient, but is not obsolete either.
What I meant to say is that the redirection format ">!" is no longer mandatory for non-existing output files in neither shell, but can still be used in csh and tcsh nonetheless. ksh and bash don't recognize this format, however.
Thx for the points!

Thx for the reply.
Shell Scripting
The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.
