How do I rename a process on Linux?

Question

I'm using Python, for what it's worth, but will accept answers in any applicable language.

I've tried writing to /proc/$pid/cmdline , but that's a readonly file.

I've tried assigning a new string to sys.argv[0] , but that has no perceptible impact.

Are there any other possibilities? My program is executing processes via os.system (equivalent to system(3) ) so a general, *NIX-based solution using an additional spawning process would be fine.

Answer 1

这似乎是你在寻找...

Answer 2

Writing to *argv will change it, but you'll need to do that from C or the like; I don't think Python is going to readily give you access to that memory directly.

I'd also recommend just leaving it alone.

Answer 3

如果使用subprocess.Popen而不是os.system，则可以使用executable参数指定要执行的实际文件的路径，并将要显示的名称作为参数args列表中的第一项传递。
