systemctl 输出被截断

Question

需要为此命令 grep 输出：

systemctl | grep failed

问题是它没有显示完整的单位：

systemd-...-clean.service loaded failed failed        Cleanup of Temporary Directories
systemd-...-setup.service loaded failed failed        Recreate Volatile Files and Directories
tcsd.service              loaded failed failed        LSB: Init script for TCSD
cups.socket               loaded failed failed        CUPS Printing Service Sockets

你可以看到单位显示，如：systemd-...es-clean.timer 对systemd-tmpfiles-clean.service

我试过一个文件：

systemctl --failed > file

或者猫：

systemctl --failed | cat

但问题是一样的。我需要了解为什么会发生这种情况以及如何解决它。

这与管道无关，是systemctl的行为。使用--full开关获取全名：

--full
    Do not ellipsize unit names and truncate unit descriptions in the
    output of list-units and list-jobs.
