How can I find a specific process with "top" in a Mac terminal
提问by c1p0
I've tried top | grep skypefor example but it doesn't work. I'm trying to find a specific process by name.
top | grep skype例如，我已经尝试过，但它不起作用。我正在尝试按名称查找特定进程。

Use this instead: ps -ax | grep -i skype
改用这个： ps -ax | grep -i skype

Use: top -l 0 | grep Skype
利用： top -l 0 | grep Skype
The 0 is for infinite samples. You can also limit the number of samples to a positive number.
0 代表无限样本。您还可以将样本数限制为正数。

if you really love top, you could try:
如果你真的喜欢顶级，你可以试试：
top -b -n 1 | grep skype
e.g.
例如
kent$ top -b -n 1 |grep dropbox
4039 kent 20 0 184m 14m 5464 S 0 0.4 0:58.30 dropbox

On Linux, the topcommand supports the -poption to monitor specific PIDs. On MacOS, the -poption is called -pidinstead.
在 Linux 上，该top命令支持-p监控特定 PID的选项。在 MacOS 上，-p会-pid改为调用该选项。
# Get the PID of the process
pgrep Skype
# Then
top -pid <put PID here>
# Or more succinctly:
top -pid `pgrep Skype`
If you do this a lot, you could turn this into a function and add it to ~/.bash_profile:
如果你经常这样做，你可以把它变成一个函数并将它添加到 ~/.bash_profile：
# Add this to ~/.bash_profile
function topgrep() {
if [[ $# -ne 1 ]]; then
echo "Usage: topgrep <expression>"
else
top -pid `pgrep `
fi
}
Now you can simply use topgrep Skypeinstead, which will run like usual but it will only show the process(es) matching expression.
现在您可以简单地topgrep Skype改用它，它会像往常一样运行，但只会显示匹配的进程expression。

I would recommend using ps -ax | less
我建议使用 ps -ax | less
From within less, you can type in /skypeEnterto search for processes with names containing "skype".
在 中less，您可以输入/skypeEnter以搜索名称包含“skype”的进程。

Tested on MacOSX Mojave. It works a bit different than linux.
在 MacOSX Mojave 上测试。它的工作原理与 linux 有点不同。
top -piddoesn't expect a comma separated list of pids, it expects only one pid. So I had to changed it a little to work with several pids.
top -pid不需要逗号分隔的 pid 列表，它只需要一个 pid。所以我不得不稍微改变它以使用几个pid。
top -pid $(pgrep -d' -pid ' -f Python)
filter all Python process on top. It essentially becomes something like this:
在顶部过滤所有 Python 进程。它本质上变成了这样：
top -pid 123 -pid 836 -pid 654
