These are the ones that decide how and where your lovely data shows up. Pick your vibe ⭐

  • -h, --help — Show this help message. Your lil safety net when you're like "wait what" 🙈
  • -A, --showall — Show all esmi parameter values. Not some. ALL. No cap 👑
  • -V, --version — Show e-smi library version. Gotta know what you're working with, bestie 💜
  • **--testmailbox [SOCKET] [VALUE<0-0xFFFFFFFF>]** — Test HSMP mailbox interface. You hand it a [SOCKET]and a[VALUE<0-0xFFFFFFFF>]` and it goes and pokes the mailbox for you 📬

  • --json — Print output on console as json format [applicable only for get commands] ✨

Heads up bestie: both --json and --csv are only for get commands, so don't come for them on anything else, they will not serve 🫠
  • --initialdelay [INITIAL_DELAY] <TIME_RANGE<ms,s,m,h,d>> — Initial delay before start of execution. Like a lil pause before the show starts ⏳ and your time range can be in ms, s, m, h, or d 🌈
  • --loopdelay [LOOP_DELAY] <TIME_RANGE<ms,s,m,h,d>> — Loop delay before executing each loop. A lil breather between rounds 🦋 time range again: ms, s, m, h, d
  • --loopcount [LOOP_COUNT] — Set the loop count to the specified value [pass "-1" for infinite loop]. Set it to "-1" if you want it to go forever, and I do mean forever, no take-backs 💀
  • --stoploop [STOPLOOP_FILE_NAME] — Set the StopLoop file name, loop will stop once the stoploop file is available. So like... you name a file, and the moment that file shows up, the loop is out 🧚
  • --printonconsole [ENABLE_PRINT<0-1>] — Print output on console if set to 1, or 0 to suppress the console output. 1 = talk to me, 0 = shhh 🤫
