BusyBox没有ps参数

BusyBox没有ps参数

The BusyBox replacement doesn support options like ps -ef,busybox的ps命令没有参数选项类似ps -ef

一个解决办法就是自己去下载ps的源代码来交叉编译。

One way to go would be to build your own version of ps with all the options you need using the source code of procps

The only solution I see here is to build a needed version of ps from source code. Of course, do not forget that you need to cross-compile it as its for embedded system that I assume runs on ARM or other non x86 architecture. After that simply replace binary on your embedded system with the newly built one (don forget backup, just in case).

下面是编译步骤:
 

1. Download procps source from http://procps.sourceforge.net/download.html

2. Get procps 3.8.2 patches from http://www.linuxfromscratch.org/lfs/view/7.1/chapter03/patches.html

3. Follow instructions at http://www.linuxfromscratch.org/lfs/view/7.2/chapter06/procps.html
