Command Line Tools and History
Posted by Harald van Breederode on January 17, 2009
While teaching an Oracle Data Guard course last week one of my students asked me how it was possible that I could recall commands in command line tools such as DGMGRL, SQL*Plus and RMAN. I told him that I use rlwrap For this purpose. I was quite surprised that he didn’t knew this because I wrote an article about this for the October 2008 issue of the Oracle University Technology Newsletter. In SQL*Plus’s Forgotten History I explain everything you need to know about this little but very useful utility. Personally I feel disabled when rlwrap is not available on systems I have to work on and it is usually the first thing I recommend to install. Besides making my life easier it also leaves a trail behind with the actions I performed.
