1. 使用 pstree -p PID

ps aux | grep firefox | grep -v grep
charles??26058??0.0? 0.0?? 4908? 1152 ???????? S??? 19:17?? 0:00 /bin/sh /usr/lib/firefox-3.5.4/run-mozilla.sh /usr/lib/firefox-3.5.4/firefox

?

charles??26073? 7.6? 3.4 284264 70164 ???????? Sl?? 19:17?? 4:36 /usr/lib/firefox-3.5.4/firefox

pstree -p 26058

?

run-mozilla.sh(26058)───firefox(26073)─┬─{firefox}(26074)
???????????????????????????????? ? ????????????????????????????????????????? ├─{firefox}(26075)
????????????????????????????????? ? ???????????????????????????????????????? ├─{firefox}(26076)

????????????????????????????????????? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? ├─{firefox}(26092)
???????????????????????????????????????????????????????????????????????????? └─{firefox}(26403)
? 2.使用 /proc

cd /proc/26073/task

ls
26073? 26074? 26075? 26076? 26085? 26086? 26087? 26092? 26403

?

3. 使用 top 命令：

top -p 26073

?

然后press shift + h:

?

?

4. 使用 ps -eLf

?

5. 檢查線程占用的內存

cat /proc/statm

?

6. 使用命令：

?

ps -Lo pid,ppid,pgid,nlwp,lwp,stat,command -p PID [plain]?view plaincopy print?

$?ps?-Lo?pid,ppid,pgid,nlwp,lwp,stat,command?-p?2053??

??PID??PPID??PGID?NLWP???LWP?STAT?COMMAND??

?2053?????1??1830????2??2053?Sl???/usr/lib/zeitgeist/zeitgeist-fts??

?2053?????1??1830????2??2054?Sl???/usr/lib/zeitgeist/zeitgeist-fts??

7.自己編寫一個腳本：

?

?

[plain]?view plaincopy print?

$?cat?/home/charles/listThread.sh??

#!/bin/bash??

cd?/proc/$1/task;??

list=$(ls);??

#echo?$list;??

printf?"%-15s?%-5s?%7s?%7s\n"?Name?State?Pid?Tid??

for?task?in?$list;?do??

list=$(cat?$task/status?|?awk?'NR?<=?4?{printf?"%s\n",?$2}');??

list2=$(echo?$list?|?tr?'\n'?'?');??

echo?$list2?|?awk?'{printf?"%-15s?%-5s?%7s?%7s\n",?$1,?$2,?$3,?$4}'??

done??

[plain]?view plaincopy print?

$?/home/charles/listThread.sh?2053??

Name????????????State?????Pid?????Tid??

zeitgeist-fts???S????????2053????2053??

gdbus???????????S????????2053????2054 ?
