Cygwin:获取进程状态

Cygwin:获取进程状态

当我top在 Cygwin 中运行时,我得到:

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

我想提取所有流程的这些列:

PID PPID S COMMAND

ps给出 PID、PPID 和 COMMAND,但是如何获取所有进程的“S”列?

编辑:

我无法使用在 GNU/Linux 上使用的内容:

$ ps -e -o pid,ppid,state,comm
ps: unknown option -- o
Try `ps --help' for more information.

$ ps --version
ps (cygwin) 1.7.33
Show process statistics

$ ps --help
Usage: ps [-aefls] [-u UID] [-p PID]

Report process status

 -a, --all       show processes of all users
 -e, --everyone  show processes of all users
 -f, --full      show process uids, ppids
 -h, --help      output usage information and exit
 -l, --long      show process uids, ppids, pgids, winpids
 -p, --process   show information for specified PID
 -s, --summary   show process summary
 -u, --user      list processes owned by UID
 -V, --version   output version information and exit
 -W, --windows   show windows as well as cygwin processes

With no options, ps outputs the long format by default

procps
:
version: 3.2.8-3

答案1

默认情况下top不显示 PPID(至少在 CygWin 中)。除此之外,您可以通过将开关与开关(运行一次)-b结合使用来使用 top 的批处理模式。我过去常常跳过前几行并粗略地选择列。-n 1awk

top -b -n 1 | awk 'NR>6 { print $1, $8, $12 }'

答案2

您可以使用ps -e -o pid,ppid,state,comm

答案3

解决方案如下:

perl -ne '/Name/ and print"\n";/(Name|Pid|Ppid|State):\s+(\S+)/ and print "$2\t";' /proc/*/status
