[Tfug] bash history duplication?

[Matt Jacob]

Hmm... In the words of Bugzilla, "WORKSFORME". Check this out:

mjacob at ned:~$ history -c
mjacob at ned:~$ pwd
/home/mjacob
mjacob at ned:~$ pwd
/home/mjacob
mjacob at ned:~$ pwd
/home/mjacob
mjacob at ned:~$ history
     3  pwd
     4  history

So that appeared to do what it was supposed to. And then I alternate 
some commands so that the last command and the current command are 
different:

mjacob at ned:~$ history -c
mjacob at ned:~$ pwd
/home/mjacob
mjacob at ned:~$ uptime
  11:52:40 up 2 days,  3:40,  1 user,  load average: 0.00, 0.00, 0.00
mjacob at ned:~$ pwd
/home/mjacob
mjacob at ned:~$ uptime
  11:52:47 up 2 days,  3:41,  1 user,  load average: 0.00, 0.00, 0.00
mjacob at ned:~$ history
     3  pwd
     4  uptime
     5  pwd
     6  uptime
     7  history

And history picked those up like it was supposed to. Maybe echo 
$HISTCONTROL and see if it's actually set like you think it is.
