Linux 下查看线程信息

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}(26085)
├─{firefox}(26086)
├─{firefox}(26087)
├─{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:

Tasks: 9 total, 0 running, 9 sleeping, 0 stopped, 0 zombie
Cpu(s): 10.3%us, 5.3%sy, 0.0%ni, 84.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
26073 charles 20 0 277m 67m 24m S 1.0 3.4 4:47.01 firefox

26075 charles 20 0 277m 67m 24m S 0.0 3.4 0:00.12 firefox
26076 charles 20 0 277m 67m 24m S 0.0 3.4 0:14.60 firefox
26085 charles 20 0 277m 67m 24m S 0.0 3.4 0:00.00 firefox
26086 charles 20 0 277m 67m 24m S 0.0 3.4 0:00.00 firefox
26087 charles 20 0 277m 67m 24m S 0.0 3.4 0:03.51 firefox
26092 charles 20 0 277m 67m 24m S 0.0 3.4 0:00.06 firefox
26403 charles 20 0 277m 67m 24m S 0.0 3.4 0:00.00 firefox

4. 使用 ps -eLf

5. 检查线程占用的内存

cat /proc/statm

6. 使用命令：

ps -Lo pid,ppid,pgid,nlwp,lwp,stat,command -p PID

[plain] view plain copy

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.自己编写一个脚本：

[plain] view plain copy

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 plain copy

print?

$ /home/charles/listThread.sh 2053

Name State Pid Tid

zeitgeist-fts S 2053 2053

gdbus S 2053 2054
