我使用 LinuxMint Wilma。

通过 apt 安装了 remmina 1.4.35。

当我打开 remmina-gnome 时，我看到：

在此处输入图片描述

当我点击按钮时，什么也没有发生。如果我添加一个热名，什么也没有改变。

我不使用 gnome-keyring。我尝试通过 ssh 连接 cli，但失败了，提示：

但是我可以不用密码进行 ssh。Remmina 尝试使用密码。

我搜索了这个任务，发现了以下较旧的问题：

但是我不能使用，awk因为我的数据是一个复杂的 CSV 文件，有多个嵌套的双引号。

假设我想删除以下重复数据（简化案例）：

Ref,xxx,zzz
ref1,"foo, bar, base",qux
ref1,"foo, bar, base",bar
ref2,aaa,bbb

在输出中我需要它如下：

Ref,xxx,zzz
ref1,"foo, bar, base",qux
ref2,aaa,bbb

没有awk解决方案，只能使用任何 CSV 解析器。

我尝试了以下内容：

mlr --csv uniq -a -g Ref file.csv

但这是一个错误。

有没有人有解决方案来防止alt+f2在 Linux Mint Xfce4 中窃取选择？

例如：我有一个 URL 可以粘贴到 URL 栏中（假设我使用过ctrl+c），然后我用打开brave-browser，alt+f2然后xfrun4由 触发alt+f2，当我粘贴时ctrl+v，而不是我的 URL 我有例子ve-browser。

也许有些东西gsettings或者我需要填写错误报告？

我尝试升级詹金斯。

我使用新的方式来使用 gpg 密钥：

wget https://pkg.jenkins.io/debian-stable/jenkins.io.key 
gpg --dearmor jenkins.io.key
mv jenkins.io.key.gpg /usr/share/keyrings/jenkins-keyring.asc

cat /etc/apt/sources.list.d/jenkins.list

deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/

apt键：

apt-key list | grep -i jenkins # nothing

# file /usr/share/keyrings/jenkins-keyring.asc
/usr/share/keyrings/jenkins-keyring.asc: PGP/GPG key public ring (v4) created Mon Mar 30 15:10:17 2020 RSA (Encrypt or Sign) 4096 bits MPI=0x99a14538d6e6150d...

但是当我跑步时apt update：

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://pkg.jenkins.io/debian-stable binary/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FCEF32E745F2C3D5

W: Some index files failed to download. They have been ignored, or old ones used instead.

怎么了？

考虑以下示例：

exec 10>&2 # duplicate STDERR to fd 10
{ echo ok; inexistantcommand; } > /tmp/both 2>&1 10>/tmp/err
exec 10>&- # close fd 10

我希望 /tmp/err 有错误，但它是空白的：

$ cat /tmp/both
ok
-bash: inixistantcommand: command not found

$ cat /tmp/err
$

我做错了什么？

编辑：

试过：

{ echo ok; qsdfghjk;  } &> >(tee /tmp/both) 2>/tmp/err

但是 /tmp/both 只有STDOUT

当您遵循文档时：

xmlstarlet edit --help

您可以阅读--var可用于将 XPath 表达式声明为变量的内容。

生成moc文件：

cat<<EOF > /tmp/file.xml
<root>
<elt>x</elt>
<!-- comment -->
<elt>y</elt>
<!-- other comment -->
</root>
EOF

这个有效，没有变量：

xmlstarlet edit \
    --var xp '//elt/following::comment()' \
    -a '//elt/following::comment()' -t elem -n p -v 'some new text' \
    -a '//elt/following::comment()' -t elem -n p -v 'some other text' \
/tmp/file.xml

这个不使用变量进行编辑：

xmlstarlet edit \
    --var xp '//elt/following::comment()' \
    -a xp -t elem -n p -v 'some new text' \
    -a xp -t elem -n p -v 'some other text' \
/tmp/file.xml

使用变量我想念什么？

我使用这个 Vagrantfile：

Vagrant.configure("2") do |config|

  config.vm.box = "jonatasbaldin/solaris11"
  config.vm.box_version = "1.0.0"
  
end

成功vagrant up，但vagrant ssh退出时返回 255 代码，根本没有任何输出。要调试，我做

$ ssh -v vagrant@localhost -p 2222

我得到：

多年来，我一直试图理解这个概念，但此时对此的了解还不完整。

这里有没有人可以通过示例来制作一种教程或很好的解释

  • 开一个新的fd
  • 读自fd
  • 使用fd
  • 关闭fd

我已经阅读了https://www.gnu.org/software/bash/manual/html_node/Redirections.html和man bash，但不清楚，根本没有具体且易于理解的示例。

如果有人能很好地解释它，那将是一个有价值的答案，不仅对我而言。大多数时候语法有点混乱。
有时需要exec，有时不需要。

我知道如何映射鼠标单击F1，F2和F3（分别左键单击、中键单击、右键单击）：

xkbset m   # required, but disable keypad
xmodmap -e "keycode 67 = Pointer_Button1 Pointer_Button1"
xmodmap -e "keycode 68 = Pointer_Button2"
xmodmap -e "keycode 69 = Pointer_Button3"

但这需要我使用xkbset m慢键模式：

4如果我从键盘按下，它会将光标移到左侧。我不需要这个功能，只需要上面的映射。

我试图用 来弄清楚xdotool，但我不知道如何处理按下/释放键（用于拖放）

xdotool mousedown 1
xdotool mouseup 1

如何不使用此模式或如何重新映射所有键盘键？

请问键盘上的数字和算术符号怎么样？

还有其他解决方案吗？

有关 Debian (cinnamon) 和 Archlinux (xfce) 所需的信息，如果可能，我想要一个不基于窗口管理器的解决方案。

编辑：

尝试了此解决方案，但我无法使用F1.

在~/.xbindkeysrc：

"xdotool mousedown 1"
    F1
"xdotool mouseup 1"
    F1 + Release

或者 ：

"xdotool mousedown 1"
    m:0x10 + c:67
"xdotool mouseup 1"
    m:0x10 + c:67 + Release

然后 ：

xset -r 67

编辑2

尝试使用actkbd

# actkbd configuration file
<keycode ("67")> :key : :xdotool mousedown 1
<keycode ("67")> :rel : :xdotool mouseup 1
