For that you write to /proc/self/comm, that's where top gets it from.

  Hmm, htop then? Whatever is reading /proc/self/cmdline

  It may work for top, but not ps among others. The only reliable way is clobbering argv. That's just the way it is. In my opinion, glibc should finally provide setproctitle(), so programs like postgresql or chrome (https://source.chromium.org/chromium/chromium/src/+/main:base/process/set_process_title_linux.cc;l=77 https://source.chromium.org/chromium/chromium/src/+/main:bas...) don't have to resort to argv hacks.

    There's prctl https://man7.org/linux/man-pages/man2/PR_SET_NAME.2const.html https://man7.org/linux/man-pages/man2/PR_SET_NAME.2const.htm... that writes to /proc/self/comm

  This isn't true for the majority of operating systems.
