출력 전체 명령 이름을 사용할 수 있습니까 lsof -nP -i4UDP?

매뉴얼에서 (아래 참조)와 같은 적합한 옵션을 찾고 있었지만 -V전체 이름이 생성되지 않습니다 COMMAND. 즉, systemd-resolve다음과 같이 나타납니다 systemd-r.

$ sudo lsof -V -nP -i4UDP
COMMAND    PID            USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

에서 man lsof:

+c w     defines the maximum number of initial characters of the name,
         supplied by the UNIX dialect, of the UNIX command associated with a
         process to be printed in the COMMAND  column.  (The lsof default is nine.)

         Note  that  many UNIX dialects do not supply all command name characters
         to lsof in the files and structures from which lsof obtains command name.
         Often  dialects limit the number  of characters supplied in those sources.
         For example, Linux 2.4.27 and Solaris 9 both limit command name length to
         16 characters.

         If w is zero ('0'), all command characters supplied to lsof by the UNIX
         dialect will be printed.

         If  w  is  less  than the length of the column title, ``COMMAND'', it will
         be raised to that length.

이를 고려하여 +c0모든 것을 사용 가능하도록 추가할 수 있습니다.

$ sudo lsof -V -nP -i4UDP +c0
COMMAND         PID            USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
systemd-resolve 176 systemd-resolve   11u  IPv4  11204      0t0  UDP *:5355
