如何用 N 个空格替换一个空格？

9

有很多 SE 帖子涉及用一个空格替换多个空格，但似乎没有关于用多个空格替换一个空格的帖子。

输入数据：

将八个空格硬编码到sed工作中，但很难一眼看出添加了多少个空格：

$ head -n20 $X | paste -sd' \n' | sed -e 's/F /F         /'

类似的东西sed -e 's/F /F \{8,\}/'就是我所寻找的。

等一切搞定之后，我再处理incr backup线路。欢迎提供XY问题解决方案。

如何在终端中呈现交互式 html5？

5

我想要一个快捷界面，可以显示一些信息，并允许我点击信息的不同部分以查看详细信息。我想把它保留在终端内。

经过一番阅读，感觉HTML'5 中的细节元素是一个不错的方法 - 因为它避免了编码。

不幸的是，lynx、w3m 和glow markdown 渲染器都不支持这一点。

有没有支持 HTML 5 的命令行浏览器/渲染器？

解决方法

我可以在 curses 中实现这一点 - 因为它支持点击，但这感觉像是工作。

我可以在 emacs 中实现这一点，因为 emacs 支持折叠......这可能就是我要做的......但它不是很独立。

kitty是一个终端模拟器，它扩展了终端协议以支持图像和字体。看起来人们对它的兴趣足以让基于 Chromium 的浏览器（awrit）在其中实现……所以也许我可以使用它。但它似乎是 kitty 独有的。

我尝试过的事情

我尝试了声称支持 html5 的chawan - 但没有处理细节元素 - 它们是 html5 的一部分 - 以及我感兴趣的部分。
我尝试了browshRedGrittyBrick 的建议。在我的 ubuntu 设置上，这个方法没有立即起作用 - 我想是因为Firefox 现在在 ubuntu 上运行snap。我可能可以找到一个解决方法。它有一个 docker 镜像，我现在正在尝试 - 它似乎挂了Waiting for Firefox to connect...
我无法让 awrit 运行——无论是在它的主分支还是电子分支上（详细信息如下——尝试在问题关闭之前解决这个问题）。

使用临时窗口大小加载 PuTTY 会话？

6

有时（但只是有时）我需要加载与配置的窗口大小不同的 PuTTY 会话。

类似于：

putty -load SomeServer -winrows 28 -wincols 142

我查看了在线文档，但什么也没看到。（PuTTY“管理器”允许您将相同的设置级联到多个会话；它们是否会在后台更新许多（也许几十个）注册表项？）

是的，我可以用鼠标调整窗口大小，但我会尽量将手指放在键盘上，因为这是重复性的工作（我已经尽我所能将其编写成脚本）。

在 PowerShell 中运行具有可变数量参数的外部命令？

4

PS 5.1.22621.4391（我被它困住了）

有时我需要运行这个：

plink -t -load "$Session" -batch -m $ShellFile

但有时我需要添加另一个选项：

plink -t -load "$Session" -batch -m $ShellFile -pw $SshPw

这看起来太黑客了，但效果不好：

if ($SshPw)
    { plink -t -load "$Session" -batch -m $ShellFile -pw $SshPw } 
else
    { plink -t -load "$Session" -batch -m $ShellFile }

我尝试将命令构建为字符串，然后通过执行&，但失败了，因为显然&处理的只是程序名称。

PS C:\Users> $X="plink -t -load `"$Session`" -batch -m $ShellFile"

PS C:\Users> $X
plink -t -load "FIS-Q-LBX-PGS-101-a" -batch -m C:\<somedir>\daily.txt

PS C:\Users> &$X
& : The term 'plink -t -load "FIS-Q-LBX-PGS-101-a" -batch -m C:\<somedir>\daily.txt' is not recognized as the name of a cmdlet, 
function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

+  ~~
    + CategoryInfo          : ObjectNotFound: (plink -t -load ...\Temp\daily.txt:String) [], CommandNotFoundException

有解决方法吗？我的 Google 能力不够强。

如何用外层引号包裹带有多个嵌套引号的字符串？

以下字符串在命令行中有效，我想将其括在外部引号中以将其用作 Python 应用程序中的字符串，但不知道如何对其进行转义。有人可以帮忙吗，或者有应用程序或网站可以帮我做这件事吗？

PowerShell 或 plink 正在吃掉双引号内的单引号

PS版本 5.1.22621.4391

plink：版本 0.82

我仔细研究了通过plink 从 powershell 中正确地转义 awk 命令，但其中一个程序一直在吃单引号。

有没有办法通过 plink 运行这个命令？

echo "select setting from pg_settings where name = 'server_version';"

PS C:\Users> plink -load "FIS-S-LBX-PGS-202-a" -batch echo --% "select setting from pg_settings where name = 'server_version';"

为什么 Clink 会替换我的命令中的文本？我该如何禁用此行为？

6

我在终端中使用 Clink 时遇到了意外行为。我的系统是 Windows 10.0.18363。当我输入：

(venv) C:\marat\programs\BASE\MiriadRobot>!p

... 在我按下 Enter 键之前，!p它就被突出显示，并且下面出现以下文本（py这是我使用的最后一个以 p 开头的命令）：

History expansion for "!p": py

当我按下 Enter 键时，执行的命令显示!p已被替换为py。运行clink history确认了这一点：

  500  2025-01-22 08:16:42  py

但是，如果我在感叹号后输入以前未在命令中使用过的字母，则不会突出显示任何内容，也不会替换任何内容。

如果我运行，clink history我发现什么都没有被替换：

  502  2025-01-22 08:37:13  !b

它是如何工作的以及我如何禁用此行为？

以管理员身份运行 .bat 文件时如何避免出现 Windows 警告窗口

5

我使用以管理员身份运行的快捷方式（在快捷方式选项中设置）来运行需要管理员权限的 .bat 文件。现在，每次运行时，我都必须允许它，因为 Windows 会弹出警告窗口。

我试过https://superuser.com/a/1613169/313763，但这似乎只适用于 .ps1，而不适用于 .bat 文件？

是否可以在不允许的情况下运行快捷方式？

如何从命令行更改 macOS 终端背景颜色？

6

我正在尝试按照此问题以编程方式更改我的 Mac 终端的背景颜色，并且接受的答案指向此CSV以获取颜色列表，以供以下使用osascript：

tell application "Terminal"
   set background color of window 1 to {65535, 33667, 49601}
end tell

我似乎找不到此灰度滑块的 RGB（？）颜色。

如果我更改为 RGB，则会看到以下内容：

但是当我用数字运行上面的脚本时25 25 25，我看不到这种颜色——我看到的是完全的黑色。
