I want to watch a given process in unix over time to see what time memory grows (its a long running job)
我想观察unix中给定的进程随时间增长的情况(这是一项长期的工作)
I guess I could do
我想我可以
ps -aux | grep PID
and run this from cron every 5 minutes, but it seems there should be a better way.
每5分钟从cron那里运行一次，但似乎应该有更好的方法。
Is there a way I can use sar to do this?

I use this:
我用这个:
$ ps -o rss $(pgrep executablename)
Put that in a while loop or use watch to monitor it over time coupled with tail. You can also tee it to a file and have gnuplot plot it for you and refresh every few seconds.
将其放入一个while循环中，或者使用watch随着时间的推移与tail一起监控。您还可以将它赋值到一个文件，并让gnuplot为您绘制它，并每隔几秒钟刷新一次。
