Problem Registering for Forum -> date -u +%W$(uname)...

date -u +%W$(uname)|sha256sum|sed 's/\W//g'

Does not work correctly for bash on my Linux box, bash-4.1_p9, it eats the "-" at the end of the line.

It is supposed to remove the 2 spaces between the hash and the dash, I had to put the dash back before the registration page would accept my input

date -u +%W$(uname)|sha256sum|sed 's/ //g'

or

date -u +%W$(uname)|sha256sum|sed 's/\s//g'

Do work correctly for bash-4.1_p9.

bash 4.2.037-1 from [core] doesn't display the '-' either.

Works fine here and you would assume that on install of an Arch system it would also work fine for those.  Is it convenient?  Not really, but: it is two-fold useful.  1) It really, really cuts down on spammer accounts.  And 2) Arch is a distribution for competent Linux users - you have to be, at least minimally, to do that command.

headkase, you mean it failed for you as well.  Your output does not have the trailing dash.

I am assuming (based on the OP) that the dash is necessary to pass forum registration.  So given a current and up to date arch system and a fully competant user, registration would fail.

Ok, it failed - just tried to register with the output.  However, the two points for its rationale still stand.

Re: Problem Registering for Forum -> date -u +%W$(uname)...

Maybe I'm confused, but it seems the '\W' in the sed statement is supposed to filter out the spaces and the dash.

Edit: My point being the problem is with the forum code, not the shell.

There is nothing wrong with using a complex command to qualify users, just make sure it works for all shells. I posted 2 other forms of the command that work for my bash shell. I think the one with the simple space would work on any shell.
