mac 上PS命令使用指北

Posted 2021-09-13 宋冬野

正常的ps命令是打印出来PID TTY TIME CMD四个字段

  PID TTY           TIME CMD

看到挺诡异的没,CMD内容过长被截断了,UICrawler这一行本身很长,如何显示出完整的路径呢,ps -f 打印出完整信息(后来发现这个把终端宽度拖宽一点就可以显示了,他只是一行显示不下不回换行,害我弄好久,垃圾,ps -f默认应该是可以多行显示)

 ps -f

内容是齐全了，怎么才能把除了CMD字段的其他内容去掉ps -fo command?

不行啊-f会把所有的字段显示出来,后来搜索ps -o command

ijm@172-10-20-5 ~ % ps -o command
COMMAND
-zsh
ios_webkit_debug_proxy -f chrome-devtools://devtools/bundled/inspector.html
-zsh
-zsh
-zsh
/Library/Frameworks/Python.framework/Versions/3.8/Resources/Python.app/Contents/MacOS/Python ocrServer.py
-zsh
-zsh
/usr/bin/java -jar UICrawler-2.0.jar -u d4917fbadf4b71db3c9b3a835f100099b0432442 -s 127.0.0.1 -t 4723 -f config_ios.yml -b com.tencent.weread -o out_file -log

这里只会展示终端启动的一些进程,没有终端的进程是显示不出来.命令-A或-e解决这个问题ps -Ao command或ps -eo command
最终命令我要搜索UICrawler进程:
ps -Ao command |grep UICrawler

ijm@172-10-20-5 ~ % ps -Ao command |grep UICrawler
grep UICrawler
/usr/bin/java -jar UICrawler-2.0.jar -u d4917fbadf4b71db3c9b3a835f100099b0432442 -s 127.0.0.1 -t 4723 -f config_ios.yml -b com.tencent.weread -o out_file -log
