该脚本将帮助你确定高 CPU 消耗进程在 Linux 上运行了多长时间。

# vi /opt/scripts/long-running-cpu-proc.sh#!/bin/bashps -eo pid,user,ppid,%mem,%cpu,cmd --sort=-%cpu | head | tail -n +2 | awk '{print $1}' > /tmp/long-running-processes.txtecho "--------------------------------------------------"echo "UName     PID  CMD            Process_Running_Time"echo "--------------------------------------------------"for userid in `cat /tmp/long-running-processes.txt`dousername=$(ps -u -p $userid | tail -1 | awk '{print $1}')pruntime=$(ps -p $userid -o etime | tail -1)ocmd=$(ps -p $userid | tail -1 | awk '{print $4}')echo "$username $userid $ocmd $pruntime"done | column -techo "--------------------------------------------------"

给 long-running-cpu-proc.sh 设置可执行的 Linux 文件权限。

# chmod +x /opt/scripts/long-running-cpu-proc.sh

运行此脚本时，你将获得类似以下的输出：

# sh /opt/scripts/long-running-cpu-proc.sh----------------------------------------------------UName     PID  CMD       Process_Running_Time----------------------------------------------------daygeek  5214  Web       01:18:48daygeek  5748  Web       01:08:20daygeek  8043  inkscape  22:11daygeek  5269  Web       01:18:31daygeek  1712  Web       10:44:50daygeek  5335  RDD       01:17:54daygeek  1639  firefox   10:44:51daygeek  7793  nautilus  24:14daygeek  6301  Web       57:40----------------------------------------------------

2）检查高内存消耗进程在 Linux 上运行了多长时间的 Bash 脚本

该脚本将帮助你确定最大的内存消耗进程在 Linux 上运行了多长时间。

# sh /opt/scripts/long-running-memory-proc.sh#!/bin/bashps -eo pid,user,ppid,%mem,%cpu,cmd --sort=-%mem | head | tail -n +2 | awk '{print $1}' > /tmp/long-running-processes-1.txtecho "--------------------------------------------------"echo "UName     PID  CMD          Process_Running_Time"echo "--------------------------------------------------"for userid in `cat /tmp/long-running-processes-1.txt`dousername=$(ps -u -p $userid | tail -1 | awk '{print $1}')pruntime=$(ps -p $userid -o etime | tail -1)ocmd=$(ps -p $userid | tail -1 | awk '{print $4}')echo "$username $userid $ocmd $pruntime"done | column -techo "--------------------------------------------------"

给 long-running-memory-proc.sh 设置可执行的 Linux 文件权限。

# chmod +x /opt/scripts/long-running-memory-proc.sh

运行此脚本时，你将获得类似以下的输出：

# sh /opt/scripts/long-running-memory-proc.sh----------------------------------------------------UName    PID   CMD       Process_Running_Time----------------------------------------------------daygeek  1639  firefox   10:44:56daygeek  2997  Web       10:39:54daygeek  5269  Web       01:18:37daygeek  1712  Web       10:44:55daygeek  8043  inkscape  22:17daygeek  5214  Web       01:18:54daygeek  1898  Web       10:44:48daygeek  1129  Xorg      10:45:07daygeek  6301  Web       57:45----------------------------------------------------
