New subject: [Zope] [ANN] zshell: The Zope Shell

3 May 2001

      Hi there,

I'm pleased to announce you the Zope Shell version 0.001.

The Zope shell is a GPLed Python Script which makes some of the most
commonly used unix shell commands available from within Zope, to manage
the ZODB contents. You'll find this 155 lines script attached to this
message. 

As for the 0.001 version which is attached to this message, the following
commands are recognized: cd, cp, mv, rm, ls

there are some restrictions however, and it doesn't seem to work with
absolute paths, read the source for details and the future commands.

zshell accepts an unlimited number of commands to launch in a single Zope
transaction, so feel free to combine these five commands to do some very
complicated stuff. Despite its current limitations it works fine here on
Zope 2.3.2+Hotfix0501.

Please feel free to send me any comment about this software. 

Such similar functionnality included in Zope's core would make me VERY
happy. 

hoping this helps.

#
# This is the Zope shell, an attempt at making the most common
# Unix shell commands available from within Zope.
#
# As of May 3rd 2001, version 0.001, the following commands
# are recognized:
#
#	cd, rm, mv, cp, ls
#
# * cd accepts a single path as an argument
# * rm accepts many path arguments
# * mv and cp last argument is the destination folder, every previous
#   argument is an object id in the current folder
# * ls accepts many meta types as its arguments
#
# The future:
#
# in the future I'd be interested in adding more functionnalities
# as well as making it a complete Zope product, splitting it
# in one method per command, and making the accepted syntax much more
# match Unix shell's one.
# adding support for a find command is also high on my priority list
#
