How does this script for naming iTerm tabs work?
提问by Deonomo
I'm trying to name my iTerm tabs and found this link.Here is the pertinent part of the guy's post:
我正在尝试命名我的 iTerm 选项卡并找到了这个链接。这是该人帖子的相关部分：
I wrote a simple script, which I call “nametab”, which allows you to name the tab you are in from the command line. You just type something like:
$ nametab New tab nameIf you'd like to use this yourself, here is the code:
#!/bin/bash # A simple script which will name a tab in iTerm # usage: # $ nametab New tab name echo -ne "3]0;"$@"7"$ nametab New tab name
我写了一个简单的脚本，我称之为“nametab”，它允许你从命令行命名你所在的选项卡。您只需键入以下内容：
#!/bin/bash # A simple script which will name a tab in iTerm # usage: # $ nametab New tab name echo -ne "3]0;"$@"7"chmod u+x nametab.sh如果你想自己使用它，这里是代码：
echo TERM=$TERM
I have created a directory $HOME/dev/bash_scriptsand placed a file in that directory called nametab.sh. I then switched to that directory and ran the command
我创建了一个目录$HOME/dev/bash_scripts并在该目录中放置了一个名为nametab.sh. 然后我切换到该目录并运行命令
TERM=xterm-256color
But when I try to name my current tab in iTerm by typing nametab.sh New tab hellooooo, nothing happens. I also tried nametab.sh hellooooo, and nothing happens.
但是当我尝试通过键入在 iTerm 中命名我当前的选项卡时nametab.sh New tab hellooooo，没有任何反应。我也试过nametab.sh hellooooo，没有任何反应。
Can you help me understand what I don't understand?
你能帮我理解我不理解的东西吗？

If you want to have an alias for changing the tab name, you can actually do it by defining a function in your .profile/.bashrc file like this:
如果您想使用别名来更改选项卡名称，实际上可以通过在 .profile/.bashrc 文件中定义一个函数来实现，如下所示：

I was having your same problem - but I saw the tab name briefly flash before going to back to what it was: the shell and the cwd. Turns out I had an environment variable changing the tab name on every shell command, so this fixed it for me:
我遇到了同样的问题 - 但我看到标签名称短暂闪烁，然后再回到原来的样子：shell 和 cwd。原来我有一个环境变量在每个 shell 命令上更改选项卡名称，所以这为我修复了它：
##代码##Now: echo -e "\033];MY_NEW_TITLE\007"
现在： echo -e "\033];MY_NEW_TITLE\007"
..works just fine and persists.
..工作得很好并且持续存在。

This is a function. You can add it to your ~/.bashrc(or something similar, like a ~/.bash_profile). To rename the tabs, you can then do this:
这是一个函数。您可以将它添加到您的~/.bashrc（或类似的东西，如~/.bash_profile）。要重命名选项卡，您可以执行以下操作：
$ rename_tab 'NEW NAME HERE'
$ rename_tab 'NEW NAME HERE'
