Subject [jira] Commented: (HBASE-447) Shell reads from stdin and writes to stdout
Date Tue, 19 Feb 2008 19:30:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12570386#action_12570386
] 

Bryan Duxbury commented on HBASE-447:
-------------------------------------

Ok, that's awesome. However, when reading from stdin and writing to stdout, we should definitely
suppress the copyright and help info. That'll just make it more difficult to use in scripts.

> Instead of HBASE-39, which would give you the ability to store queries in a file and
execute them from the shell, we should give the shell the ability to read queries from standard
input, execute the query, and then write the output to standard output. 
> The advantage of this approach is that in addition to being able to store queries in
files, you can also script against the shell. This might mean schema creation during an installation
wizard, or a shell script that queries a small number of rows, or whatever you can think of.
