Redundant "op" before options? Also CEDG::WP4::CCM::CLI should be LEDG::WP4::CCM::CLI to ensure things like correctly.

[ned21]

ah - I guess you mean of not op?

[stdweird]

retest this please

@ned21 wrt the bash buitins, i'm quite sure previous EL5 releases shipped bash that didn't have such support. i just checked on a 5.11 box, it does have it, but TUV could have backported this. the code you commented on is only run once during the souce-ing of the tabcompletion script, so it's not slowing the actual tabcompletion.

[ned21]

OK, makes sense - I make no claims to be competent at bash-ing :-) Any chance of a fix to the docs - there's a typo when you said op instead of of and the C<..> should be replaced by L<...> to link man pages together. Otherwise I think this is good to go.

@ned21 remarks fixed. could you also make a comment in #64 to indicate that that one is also fine (as this PR is based on that one).

[ned21]

I merged #64. Does anyone want to try out this new CLI before we merge it?

[stdweird]

@ned21 as long as quattor/CAF#98 is not resolved in some way, the output will be mixed with other output.
