-bash: otool: command not found, Can you teach bash a default location to look for a command?
提问by Orchid
I can find the tool command in my filesystem under:
我可以在我的文件系统中找到工具命令：
/Applications/Xcode.app/Contents/Developer/usr/bin/otool
If I specify that entire path, otool will work.
如果我指定整个路径，otool 将起作用。
/Applications/Xcode.app/Contents/Developer/usr/bin/otool -tV hello -p _main
However, since I have to be inside the folder of the hello.c file I'm referencing, bash won't find otool automatically if I just type
但是，由于我必须在我引用的 hello.c 文件的文件夹中，如果我只输入 bash 将不会自动找到 otool
otool -tV hello -p _main
I've had this same problem with a number of commands. Is there any way to set up bash so it automatically finds otool (and similar commands), without me having to writing out the entire path name each time?Thanks!
我在使用许多命令时遇到了同样的问题。有什么方法可以设置 bash 以便它自动查找 otool（和类似命令），而不必每次都写出整个路径名？谢谢！
Note: If it matters, I'm using a Mac.
注意：如果重要的话，我使用的是 Mac。
Note 2: I've read through a ton of the "Command not found" threads but none seem to answer the question of teaching bash where to look for a command by default. I feel like this question should have been answered somewhere, but haven't come across it yet. Since the only programs I'll be working with any time soon will be iOS/Xcode related, this is worthwhile shortcut.
注 2：我已经阅读了大量“未找到命令”线程，但似乎没有一个能回答教 bash 默认在哪里查找命令的问题。我觉得这个问题应该在某处得到回答，但还没有遇到。由于我将很快使用的唯一程序将与 iOS/Xcode 相关，因此这是一个值得的捷径。

PATH=$PATH:/Applications/Xcode.app/Contents/Developer/usr/bin
Put this in your ~/.bashrcto have it persist.
把它放在你的~/.bashrc里面让它坚持下去。

You can also Try using alias to do this. e.g.
您也可以尝试使用别名来执行此操作。例如
$ alias otool='/Applications/Xcode.app/Contents/Developer/usr/bin/otool'
$别名otool='/Applications/Xcode.app/Contents/Developer/usr/bin/otool'
You can also add this in your bashrc/profile file.
您也可以将其添加到 bashrc/profile 文件中。
