Prashant Kommireddi commented on PIG-2994:
------------------------------------------

Nice, I think this would be useful. Like you said backslash (with t,r,n) might be confused
with the tab, newline delimiters. How about using a colon instead?

> This feature is aimed at providing shortcuts for frequently used commands like illustrate,
dump, explain, describe, quit, help etc. This feature is inspired from postgres(psql) shortcuts.
I tried implementing a simple shortcut for quitting the grunt shell using \q with very minimal
changes. I think this feature will help save many keystrokes for users. If this feature looks
useful I can submit the current patch for review and go ahead with implementing the following
shortcuts
> \i <alias> - illustrate
> \e <alias> - explain
> \de <alias> - describe
> \du <alias> - dump 
> \h - help
> This will also be useful to view information about tables/statistics stored in HCatalog
similar to the way psql does. 
> \dt <alias> - display table
> \dm - display metadata
> etc..
> except \t, \r and \n delimiters we should be able to use all other characters as shortcuts.

> Please let me know your thoughts.
