HP-UX：每个进程的线程数

Question

HP-UX 上是否有命令可以检查和查看与进程/任务相关的所有线程。

不支持 ps -m。

Answer 1

您可以使用 pstack 显示属于特定进程的线程的堆栈跟踪。它还将为您提供 LWPID（线程 ID）。例如：

$ whereis pstack
pstack: /usr/ccs/bin/pstack /usr/share/man/man1.Z/pstack.1

$ ps -ef|grep snmpAgt|grep -v grep
   utest 27447     1  0  Aug 26  ?        1544:45 /opt/java6/bin/IA64N/java -DsnmpAgtCfg=./etc/snmpAgt.cfg -Duser.timezone=GMT+8 com.hp.snmpagt.main.SnmpAgtMain

$ pstack 27447|head -30           
27447:  /opt/java6/bin/IA64N/java

Answer 2

使用瞥见

1. % 扫视
2. SlctProc (F6)
3. 输入 PID (14065) : 14389
4. G

...
