プロセスの RUSER と EUSER を取得する方法 (FreeBSD)

Question 1

psLinuxオプションとフィールド名を FreeBSD オプションとキーワードにマッピングしようとしていますps。これは、Linux ライクなシステムと BSD スタイルのシステムとの間の主な明らかな違いの 1 つです。

まず-eFreeBSDのオプションpsは「環境も表示する」実際に必要なのは、-axFreeBSD のすべてのプロセスを表示することです。 -x制御端末のないプロセス (カーネルプロセスとデーモン) も表示しますが、デフォルトの動作ではそれらは表示されません。

Linuxpsにおけるフィールド選択について (出典man ps: ):

 euser      EUSER    effective user name. This will be the textual user ID,   if it can be obtained and the field width
                     permits, or a decimal representation otherwise. The n option can be used to force the decimal
                     representation. (alias uname, user).
 ruser      RUSER    real user ID. This will be the textual user ID, if it can be obtained and the field width permits,
                    or a decimal representation otherwise.
 suser      SUSER    saved user name. This will be the textual user ID, if it can be obtained and the field width permits,
                     or a decimal representation otherwise. (alias svuser).
 fuser      FUSER    filesystem access user ID. This will be the textual user ID, if it can be obtained and the field
                     width permits, or a decimal representation otherwise.
 f          F        flags associated with the process, see the PROCESS FLAGS section. (alias flag, flags).
 comm       COMMAND  command name (only the executable name). Modifications to the command name will not be shown.
                     A process marked <defunct> is partly dead, waiting to be fully destroyed by its parent. The output in
                     this column may contain spaces. (alias ucmd, ucomm). See also the args format keyword, the -f option,
                     and the c option.
                     When specified last, this column will extend to the edge of the display. If ps can not determine
                     display width, as when output is redirected (piped) into a file or another command, the output width
                     is undefined. (it may be 80, unlimited, determined by the TERM variable, and so on) The COLUMNS
                     environment variable or --cols option may be used to exactly determine the width in this case. The w
                     or -w option may be also be used to adjust width.
 label      LABEL    security label, most commonly used for SE Linux context data. This is for the Mandatory Access
                     Control ("MAC") found on high-security systems.

psキーワード選択に関するFreeBSD マニュアルより:

 uid        effective user ID (alias euid)
 user       user name (from UID)
 ruid       real user ID
 ruser      user name (from ruid)
 svuid      saved UID from a setuid executable
 state      symbolic process state (alias stat)
 comm       command
 label      MAC label

FreeBSDにはこれに相当するものはない。フューザーなので、スキップしましょう。

したがって、あなたの場合は次のように翻訳されます。

ps -axo user,ruser,svuid,state,comm,label |grep <process_name>
