我如何捕获 apt-get ‘注意，选择’

  • 772

命令apt-get install libgnutls30会在控制台中打印“注意，选择‘libgnutls30t64’而不是‘libgnutls30’”。如果 stdout 和 stderr 重定向到文件，则不会出现在任何文件中。strace似乎表明在这种情况下它会重定向到 /dev/null。

有没有办法将该消息捕获到文件中？

apt

    看起来，当输出是 TTY 设备时，该apt系列会将信息消息写入，否则写入 。使用程序的相同“技巧” ，在此处描述：/dev/tty/dev/nullscriptapt-file

    似乎也适用于apt，例如

    $ script -c 'sudo apt-get install --dry-run libgnutls30' -O apt.log
Script started, output log file is 'apt.log'.
[sudo] password for steeldriver:

Reading state information... Done
Note, selecting 'libgnutls30t64' instead of 'libgnutls30'
libgnutls30t64 is already the newest version (3.8.3-1.1ubuntu3.1).
libgnutls30t64 set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded.
Script done.

    然后

    $ cat apt.log
Script started on 2024-08-22 13:01:25-04:00 [COMMAND="sudo apt-get install --dry-run libgnutls30" TERM="xterm-256color" TTY="/dev/pts/2" COLUMNS="172" LINES="38"]
