Base-Files (was Re: Unset TMP/TEMP in profile?)

[Angelo Graziosi]

In the new '.bashrc' (in base-file-3.9) there is:

# export HISTIGNORE="[ \t]*:&:[fb]g:exit"
# export HISTIGNORE="[ \t]*:&:[fb]g:exit:ls"

and I have adopted the first,

[1]
export HISTIGNORE="[ \t]*:&:[fb]g:exit"

In my previous '.bashrc' I had

[2]
export HISTIGNORE="[  ]*:&:[fb]g:exit"

With the choice [1], command like

tar -cavf foo.tar.bz2 foo.txt

are ignored from history. Is this to be expected? What exactly does it 
mean '[ \t]'?


Thanks,
Angelo.
