我需要在其他显示器上从脚本终端打开 Chromium 中的新选项卡。当我打开时，我的终端会从 Xorg 或 GTK 接收日志（我不知道是谁打印的）。我使用了以下命令：
DISPLAY=:0 chromium-browser &
好的！此命令可以正常打开 Chromium，但我的脚本仍处于锁定状态，因为日志已发送到我的终端，如下所示：
--disable-quic --enable-tcp-fast-open --disable-gpu-compositing --ppapi-flash-path=/usr/lib/chromium-browser/libpepflashplayer.so --ppapi-flash-args=enable_stagevideo_auto=0 --ppapi-flash-version=

此行为在其他应用程序中也会发生，例如lxpanel。
请问，如何禁用此日志或在其他显示器上打开任何应用程序而不使用日志。
答案1
像这样重定向所有输出：1>/dev/null 2>&1，例如：
DISPLAY=:0 chromium-browser 1>/dev/null 2>&1 &
这会将标准输出重定向至黑洞（/dev/null），并将错误输出（2）重定向至标准输出（1），因此它也会消失在“/dev/null”中。
