Don't write command to history when it's the same as previous command

[idefix]

When you issue the same command multiple times after each other in the Terminal, they all get written to .bash_history. This is extremely frustrating when you move up in the history with the up-arrow key.

I would like to see this changed; just as changeset:30953 did for the history in KDL.

This could probably be considered a duplicate of ticket #2118 ... this is builtin bash behavior that's been changed in more recent versions of bash, at least based on my linux install here.

[pulkomandy]

seen in my .bashrc in debian:

# don't put duplicate lines in the history. See bash(1) for more options # don't overwrite GNU Midnight Commander's setting of `ignorespace'. export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups # ... or force ignoredups and ignorespace export HISTCONTROL=ignoreboth

Should this work ?

Replying to pulkomandy:

Yes, I issued export HISTCONTROL=ignoredups on the command line and it now behaves as I would like it to.

I would like to see this behaviour the default; but if it's the default in more recent versions of bash (as anevilyak pointed out), this ticket might as well be closed as duplicate of ticket:2118.

Based off pulkomandy's information, I'm actually no longer certain if that's a default or something this particular distro put into the default bashrc, which we could certainly do in Haiku as well in any case.

Yes, please. Apparently, even ​Ubuntu is doing it. :)

Done in hrev31953. Thanks for all the research!
