I'm running Minecraft under Linux, which involves running an executable .jar file. This means it shows up as "java" under ps, rather than "minecraft". I would like to assign it the process name "minecraft".
我在Linux下运行Minecraft,它涉及运行可执行的.jar文件。这意味着它在ps下显示为“java”,而不是“minecraft”。我想为它分配进程名称“minecraft”。
Looking around, I found the following tip for assigning a process name via bash:
环顾四周,我发现以下提示通过bash分配进程名称:
how to change the name of a Java application process?
如何更改Java应用程序进程的名称?
exec -a goodname java ...
I usually run with:
我经常跑:
java -cp ~/Games/Minecraft/Minecraft.jar net.minecraft.LauncherFrame
So tried make a bash script:
所以尝试制作一个bash脚本:
#!/bin/bash
exec -a minecraft java -cp ~/Games/Minecraft/Minecraft.jar net.minecraft.LauncherFrame
But when I run this, it still shows up as "java" under the ps command.
但是当我运行它时,它仍然在ps命令下显示为“java”。
What am I doing wrong?
我究竟做错了什么?

It works for me. I haven't tested with java, but I tested with sleep:
这个对我有用。我没有用java测试,但我测试了睡眠:
victor@vz:~$ exec -a minecraft sleep 1m &
[1] 3858
victor@vz:~$ ps x | grep mine
3858 pts/2 S 0:00 minecraft 1m
3860 pts/2 S+ 0:00 grep --color=auto mine
victor@vz:~$
However, this seems to be merely a cosmetic change as far as I can tell by the documentation:
然而,据我所知,这似乎只是一个整容变化:
victor@vz:~$ help exec exec: exec [-cl] [-a name] [command [arguments ...]] [redirection ...] Replace the shell with the given command.
victor @ vz:〜$ help exec exec:exec [-cl] [-a name] [command [arguments ...]] [redirection ...]用给定的命令替换shell。
Execute COMMAND, replacing this shell with the specified program. ARGUMENTS become the arguments to COMMAND. If COMMAND is not specified, any redirections take effect in the current shell. Options: -a name pass NAME as the zeroth argument to COMMAND
In reference to OP's comment to this answer: I just tested it on a remote machine with java as well:
参考OP对这个答案的评论:我刚刚在带有java的远程机器上测试过:
victorz@exa:~$ javac test.java # spits out an Administrator.class file among others
victorz@exa:~$ exec -a minecraft java Administrator &
[1] 13142
victorz@exa:~$ ps x | grep mine
13142 pts/1 Sl 0:00 minecraft Administrator
13161 pts/1 S+ 0:00 grep --color=auto mine
victorz@exa:~$
Maybe you are not using the x switch to ps? I get no match unless I use the x switch.
也许你没有使用x开关来ps?除非我使用x开关,否则我得不到匹配。
