Hmm was that only recently introduced? I'm having bash4.3 with patches up to including 33. And this time I looked whether Debian added any of it's goodness ;-)
When I set e.g. in .bashrc: HISTSIZE=50 HISTFILESIZE=50 HISTTIMEFORMAT=$'%c\t' Then: $ rm .bash_history $ history -c Then start a new shell and then enter commands $ echo 1 $ echo 2 ... $ echo 50 When I do now a: $ history I see all the 50 (+/- 1) But when I leave the shell and go into a new one: $ histroy gives me only about the last 25 (i.e. echo 27 to echo 50 + "history"), and these are also the only entries in .bash_history, i.e.: #1427309882 echo 27 #1427309882 echo 28 [snip snap] #1427309882 echo 50 #1427309884 history Cheers, Chris.
