command line history

Sowser · #1 (**permalink**) 01-05-2007

I am running Solaris 8 and using ksh. The history file (.sh_history) helps a lot, but it seems to get 'reset' after a certain period of time. In other words, after some usage of the shell, the command history would disappear and start anew. Is there some facility to specify the period of time to keep the history file from being cleared?

For example, I would want to keep my history for 3 months as opposed to 2 weeks.

Thanks.

you can set the HISTSIZE environment variable for that or you can use the command

history -<no of history commands you are looking for>

eg : history -50
