pvim

#!/bin/sh
# pvim (Bourne shell script) -- captures standard input & edits it with vim
#
# Usage: pvim [ -t ] [ -d ] [ -r | -g ] [ <file_name> ]
#
# pvim prompts for a file name (if <file_name> was not specified) then copies
# standard input into it and edits it with vim.  If <file_name> was prompted
# for, or if the -t option was specified, then the file will be created in
# public-html/frames/humour/text and be made world-readable.
# Other options:
#   -d   Make a temporary file and delete it after vim quits
#   -r   Make the file world-readable
#   -g   Like -r, but makes the file group-writeable as well
