Enis Soztutar commented on HADOOP-1375:
---------------------------------------

The gnu history library can be used for browsing previous commands using <up> 
and <down> keys. 
It can be found in http://tiswww.case.edu/php/chet/readline/history.html

And gnu readline library can be used to edit commands as they are typed in. 
It can be found in http://tiswww.case.edu/php/chet/readline/rltop.html

I do not know if there is any Java implementation but i bet there are (smile)
