[HTCondor-users] Which are the valid characters for "sock"?

[Marco Mambelli <marcom@xxxxxxxx>]

Hi everyone,
is is there a specification of the valid characters for the sock parameter in a sinful string? Are dashes (-) allowed?

<tl;dr>
I'm parsing the sinful string in a shell script and I was wondering which are the valid characters in the sock parameter, the one that distinguishes the daemons when using shared port.
Its value at times come from the user (e.g. -sock option when starting a collector).
I'm mainly interested on knowing if a "-", dash, is allowed or not, because if it is it would break my current parsing.
I did non find info in the documentation and in the source code I did not find use of it but I did not find any validation blocking it (maybe I did not check well enough)

Thanks,
Marco
