So yeah for some reason I cant see any of the chrome processes, that are currently running. Even though both htop and top can see them.

So the issue is that we use ps to get the list of processes, and unfortunately it's difficult to process its output since the columns of information are ill-defined. On Linux, you can specify column width, but you can't on OSX so we currently split on whitespace, but some command names have spaces in their names which causes this bug.

Some ideas we can try:

• double check the man page and see if there's any way to format the columns to make it easier to parse
• see if there's a way for ps to not include whitespace in command names
• create a regex to match the process name by matching any characters between the PID column and CPU and MEM columns

well I know there is the -o format that can be used to specify custom formatting could try taking a look into that.

nvm, also doesn't work properly on OSX, as you said you cant specify the column width. Will try digging a little deeper to see if I can find a way.

👋 all. I think another solution can be to make use of the headers. Instead of removing the headers, we can use strings.Index to find the indexes of the following substringsPID COMM CPU MEM ARGS in the headers row. Then, we can just use those indexes to access the correct information in the subsequent rows.

If strings.Index(headers, "COMM") returns 4 and strings.Index(headers, "CPU") returns 24, we can determine that the command name is defined in the substring from index 4 to index 24.

What do you folks think?

[EDIT] There is also another way using the -o flag on macOS
