Macos ps:Get-only命令列,macos,xargs,ps,Macos,Xargs,Ps,当我运行pgrep vim | xargs ps时，它会打印 PID TT STAT TIME COMMAND 91234 s001 S+ 0:03.14 vi user.py 93868 s005 S+ 0:01.55 vi video.py 然而当我跑的时候 pgrep vim | xargs ps -o command 它打印 COMMAND -bash tmux -2 -bash vi user.py -bash -bash vi video.

当我运行

pgrep vim | xargs ps

时，它会打印

  PID   TT  STAT      TIME COMMAND
91234 s001  S+     0:03.14 vi user.py
93868 s005  S+     0:01.55 vi video.py

然而当我跑的时候

pgrep vim | xargs ps -o command

它打印

COMMAND
-bash
tmux -2
-bash
vi user.py

vi video.py
(pgrep)

我怎么能只打印

user.py
video.py

pgrep vim | xargs ps | sed 1d | perl -lane 'print $F[5]'

pgrep vim | while read pid; do ps -p $pid -o command; done|grep -v "^COMMAND"
