Server 在HP-UX中是否有通过pid获取环境变量的方法
我想知道从pid中获取HPUX中环境变量的方法 通过ps命令、文件或编程 有可能得到变量Server 在HP-UX中是否有通过pid获取环境变量的方法,server,process,pid,hp-ux,environ,Server,Process,Pid,Hp Ux,Environ,我想知道从pid中获取HPUX中环境变量的方法 通过ps命令、文件或编程 有可能得到变量 # /proc/$pid/environ in environ or ps e -ww -p $pid in linux # ps ewww pid in aix # pargs in solaris HP-UX：使用gdb跟踪，但服务器（HPUX）上没有gdb，无法安装 请让我知道。如果您可以在此主机上安装软件，最新的补丁程序应为您提供pargs（1）命令： [ hp-ux_ia64 sw ] $ /

pargs（1）[ hp-ux_ia64 sw ] $ /usr/ccs/bin/pargs -v
HP pstack/pldd/pargs version B.12.67 for HP Itanium(R) Systems.
[ hp-ux_ia64 sw ] $ /usr/ccs/bin/pargs -h
usage: pargs [-h] [-v] {-a pid | -e pid}
Given the pid of a running process, pargs prints process arguments and all
environment variables and its values.
pargs works by attaching to the process to read its memory.

pargs- 用于生成流程的核心文件
- 复制此核心文件以及可执行文件和的相应版本 libc（32位或64位，使用pldd（1）确认）到环境 哪里有gdb
- 使用gdb侵入_envp字符串表
