Hi,

by doing a

ps aux | grep UserName

The output do not keep the LF[1] 😡

I’ve found some solution online by they involve 3 or more pipe | !

On my side, I’ve made this

ps -fp $(pgrep -d, -u UserName)

But still I found it not super human readable.

Is their a native way with ps to filter users ? or to grep it but the keep the LF ?

    If I do ps aux | grep root, then the newline is preserved. So I’m not sure what exactly the problem is. There is a user option for ps, but it does not work with aux, ps --user root . You can ps ax --user root, but I’m not sure if this output is what you want.

    Btw if you grep, then I recommend using ^user , so it only matches the beginning of each line (the actual username), as ps aux | \grep ^root (notice the backslash). Do you have an alias for grep? Try \grep instead. The backslash in front of the command will use the actual command and ignore your alias.

      Here is a little bonus to have in mind: You can convert newline characters to null, then grep with option null, and at last convert null characters back to newline. Now I don’t think its useful in this case, but its good to know; therefore its a bonus information:

      ps aux | tr '\n' '\0' | \grep --null-data ^root | tr '\0' '\n'
