HP-UX：每個進程的線程數

Question

HP-UX上是否有命令檢查和查看與進程/任務相關的所有線程。

不支持ps -m。

Answer 1

您可以使用pstack顯示屬於特定進程的線程的堆棧跟蹤。它也會給你LWPID（線程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

使用一目瞭然

1. ％一目瞭然
2. SlctProc（F6）
3. 輸入PID（14065）：
4. ģ
