A few fixes to bin scripts and a proposal of a new one

[alexsavio]

• fix nipype_crash_search to print usage on no args.
• change nipype_crash_search shebang to #!python.
• add nipype_display_pklz to look into .pklz node files.

[satra]

could you please explain the rationale for this change?

[alexsavio]

"#!python" is being used in the other scripts, e.g., nipype_display_crash.
I tought about it and I am not sure if "#!/usr/bin/env python" works on Windows (if there is any Windows user here).

[satra]

@alexsavio - i'll merge this, but i'm noting here that one thing we should do is have a single nipype command tool with subcommands, like aws, singularity, docker, etc.,.

[alexsavio]

Hi Satra, thanks for the note.
I could do the subcommands for a nipype command. Would you have a dependency like click to make things easier or would you rather make something without dependencies?
I see something like:
nipype display_crash instead of nipype_display_crash,
nipype crash_search instead of nipype_crash_search,
nipype run instead of nipype_cmd, and
nipype convert instead of nipype2boutiques
?

[satra]

let's go with click for now to start a refactor.

also perhaps nipype display and nipype search, which could be augmented later

[alexsavio]

I have a first working approach. I moved nipype_display_crash to nipype crash, nipype_crash_search to nipype search, and nipype_show_pklz to nipype show.
nipype_cmd will be more involved since I have to process argv.
nipype2boutiques is straightforward, however I can't think on how to name it.

[satra]

perhaps nipype convert --format=boutiques
