bizzarely when I use the the up arrow to go back one command I often just get the command before the last one i.e. it sometimes skips the command I just did.... is there some intelligence that says 'do not put in history a command that did not work or has been repeated '......but then I use the 'history' command and the command I last did is not there...even though the command worked ?

I have only seen this on suse 10.1, csh (which is bash)....is there an option I can set ? ... I have looked around but nothing seems obvious I am using

Thanks in advance

The number of commands to remember in the command history is set via HISTSIZE variable. The default value is 500 command. Did ya set HISTSIZE variable? Try
If so increase value

Another thing is your ~/.bash_history may be linked to /dev/null to avoid login of all commands, try

well my histsize is 1000, and the file .bash_history exists and has some stuff in....

so that kind of looks ok...

as I say it seems intermitant.... is there a way of traceing my keystrokes and see what they do ?

for emple I type

$> ls
I get ls
i type

$ ls -l
i get ls -l

then I up arrow I get 'ls'

then i do
$>history

and I see
..
1137 more /etc/issue
1138 history
1139 ls
1140 history

BUT as you can see its over the 1000 HISTSIZE ... should this be allowed ??

You can set to 1000 or whatever you want. so yes it is allowed. Have you modified something related to key storks? bash man page has info about this

May the force with you!

it turns out (or rather I just noticed today !) that if you leave a white space between the prompt and the command you want to run it seems to not bother storing it in the history or elsewhere.......

so I guess its not a bug, but not a documented function !!

Cheers again
