Re: [Help-bash] Capture tab in a readline.

[Sinbad]

Hi Pierre,

Thanks for the reply. Yes i want to implement my own completion, for that i
need to detect tab, i tried '-d' option as
well, it doesn't work either. Actually i have been looking for a solution
for this for quite a while now. I'm surprised
there is no easy way to do this. If this doesn't work then i will have to
switch to either python or perl, but i'd like to
stick to bash if there is a way to do it.

Thanks
