Shell script used to view linux memory usage

In linux, the/proc/$ PID/status file provides the usage of the Process resources (memory, stack, semaphore, sub-parent process, although linux provides a lot of memory viewing commands, they all look at the overall usage and cannot view the memory usage of a single process.

This script is provided in this Article. You can view the VmRSS field in the status file to view the memory usage of the system or process. If you need it, refer to it.

Copy codeThe Code is as follows :#! /Bin/bash

Echo-n "PidName">/root/script/pid. f
Echo "MeMery">/root/script/pid. f

DOC = 'LS'
For DOCNAME in $ DOC

If [-d $ DOCNAME]; then
Cd $ DOCNAME
If [-f status]; then
MEMERY = 'grep VmRSS status | awk-F': ''{print $2} '| awk' {print $1 }''
PIDNAME = 'grep Name status | awk-F': ''{print $2 }''
If [$ MEMERY]; then
Echo-n $ PIDNAME>/root/script/pid. f
