In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines. In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident). 'htop' starts faster ('top...

Normally, system processes such as the pager and the swapper are not shown. This option makes them visible. -T, --tag-names List all available color tags and the current set of tests used for color highlighting, then exit. -a, --all Show all processes for as long as possible. This ...
top命令默认3S刷新一次,我这里加了 -n 1 只输出一次结果,不随时间刷新,方便跟踪 top 命令: NAME top - display Linux processes -n :Number-of-iterations limit as: -n number Specifies the maximum number of iterations, or frames, top should produce before ending. 关于cpu的信息是解析/proc/stat获取:...
TOP命令是Linux下常⽤的性能分析⼯具，能够实时显⽰系统中各个进程的资源占⽤状况。TOP是⼀个动态显⽰过程,即可以通过⽤户按键来不断刷新当前状态.如果在前台执⾏该命令,它将独占前台,直到⽤户终⽌该程序为⽌.⽐较准确的说,top命令提供了实时的对系统处理器的状态监视.它将显⽰系统中CPU最...

A number representing the last used processor. In a true SMP environment this will likely change frequently since the kernel intentionally uses weak affinity. Also, the very act of running top may break this weak affinity and cause more processes to change CPUs more often (because of the extra...
Also, the very act of running top may break this weak affinity and cause more processes to change CPUs more often (because of the extra demand for cpu time). k: %CPU -- CPU usage The task's share of the elapsed CPU time since the last screen update, expressed as a percentage of ...
This expect script will filter processes by name and show newly created ones. It is basically automate the user interaction with top by sending 'o' and 'COMMMAND=my_program' for you. similar to @nos Answer. file: topname.exp #!/usr/bin/expect -- if {[llength $ar...
Due to a failure in TSC synchronization,toputility does not show CPU usage properly in the RHEL7. The issue was identified in some Dell servers. 诊断步骤 Aftertophad been running for around 1 minute while high intensive CPU operations were being executed, all processes showed no CPU usage. ...
