'\r': command not found - .bashrc / .bash_profile
提问by Jasmine
I have windows, using Cygwin, trying to set JAVA_HOMEpermanently through my .bashrcfile.
我有 Windows，使用 Cygwin，试图JAVA_HOME通过我的.bashrc文件永久设置。
.bashrc:
.bashrc：
export PATH="$JAVA_HOME/bin:$PATH"
export JAVA_HOME=$JAVA_HOME:"/cygdrive/c/Program Files (x86)/Java/jdk1.7.0_05"
.bash_profile:
.bash_profile:
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
running cygwin:
运行cygwin：
-bash: $'76if': command not found
-bash: $'then\r': command not found
: No such file or directorysu//.bashrc
-bash: /cygdrive/c/Users/jhsu//.bash_profile: line 3: syntax error near unexpected token `fi'
-bash: /cygdrive/c/Users/jhsu//.bash_profile: line 3: `fi'
I am not sure if I took the commands from a tutorial that was meant for another system or if I am missing a step. Or whitespace is causing my commands not to run properly.
我不确定我是否从适用于另一个系统的教程中获取了命令，或者我是否遗漏了一个步骤。或者空格导致我的命令无法正常运行。
I've looked at multiple similar questions but I haven't found one where the question has my error exactly.
我已经查看了多个类似的问题，但我还没有找到一个问题完全符合我的错误的问题。
My home path:
我的归途：
$ echo $HOME
/cygdrive/c/Users/jhsu
$ echo ~
/cygdrive/c/Users/jhsu/
So I believe the files should be placed in the correct spot.
所以我相信文件应该放在正确的位置。

When all else fails in Cygwin...
当 Cygwin 中的所有其他方法都失败时......
Try running the dos2unixcommand on the file in question.
尝试dos2unix在有问题的文件上运行命令。
It might help when you see error messages like this:
当您看到这样的错误消息时，它可能会有所帮助：
-bash: '\r': command not found
-bash: '\r': command not found
Windows style newline characters can cause issues in Cygwin.
Windows 样式的换行符可能会导致 Cygwin 出现问题。
The dos2unixcommand modifies newline characters so they are Unix / Cygwin compatible.
该dos2unix命令修改换行符，使它们与 Unix/Cygwin 兼容。
CAUTION:the dos2unix command modifies files in place, so take precaution if necessary.
注意：dos2unix 命令会在适当的位置修改文件，因此如有必要，请采取预防措施。
If you need to keep the original file, you should back it up first.
如需保留原文件，应先备份。
Note for Mac users:The dos2unixcommand does not exist on Mac OS X.
Mac 用户注意事项：该dos2unix命令在 Mac OS X 上不存在。
Check out this answerfor a variety of solutions using different tools.
查看此答案，了解使用不同工具的各种解决方案。
There is also a unix2doscommand that does the reverse:
还有一个unix2dos相反的命令：
It modifies Unix newline characters so they're compatible with Windows tools.
它修改了 Unix 换行符，以便它们与 Windows 工具兼容。
If you open a file with Notepad and all the lines run together, try unix2dos filename.
如果您使用记事本打开一个文件并且所有行都运行在一起，请尝试unix2dos filename.

For those who don't have dos2unixinstalled (and don't want to install it):
对于那些没有安装dos2unix（并且不想安装它）的人：
Remove trailing \rcharacter that causes this error:
删除\r导致此错误的尾随字符：
sed -i 's/\r$//' filename
Explanation:
说明：
Option -iis for in-placeediting, we delete the trailing \rdirectly in the input file. Thus be careful to type the pattern correctly.
选项-i用于就地编辑，我们\r直接在输入文件中删除尾随。因此要小心正确地输入模式。

For WINDOWS(shell) users with Notepad++(checked with v6.8.3) you can correct the specific file using the option - Edit -> EOL conversion -> Unix/OSX format
对于使用Notepad++（用 v6.8.3 检查）的WINDOWS(shell) 用户，您可以使用选项更正特定文件 - 编辑 -> EOL 转换 -> Unix/OSX 格式
And save your file again.
并再次保存您的文件。
Edit: still works in v7.5.1 (Aug 29 2017)
编辑：仍然适用于 v7.5.1（2017 年 8 月 29 日）

I am using cygwin and Windows7, the trick was NOT to put the set -o igncrinto your .bashrc but put the whole SHELLOPTSinto you environment variables under Windows. (So nothing with unix / cygwin...) I think it does not work from .bashrcbecause "the drops is already sucked"
as we would say in german. ;-)
So my SHELLOPTSlooks like this
我正在使用 cygwin 和 Windows7，诀窍不是将其set -o igncr放入您的 .bashrc 中，而是将整个SHELLOPTS放入 Windows 下的环境变量中。（所以 unix / cygwin 什么都没有......）我认为它不起作用，.bashrc因为正如我们用德语所说的那样“滴已经被吸了”。;-) 所以我SHELLOPTS看起来像这样

SUBLIME TEXT
崇高的文字
With sublime you just go to
随着崇高你只是去
View - > Line Endings -> (select)Unix
查看 -> 行尾 ->（选择）Unix
Then save the file. Will fix this issue.
然后保存文件。将解决这个问题。
Easy as that!
就这么简单！

If you are using a recent Cygwin (e.g. 1.7), you can also start both your .bashrcand .bash_profilewith the following line, on the first non commented line:
如果您使用的是最近的 Cygwin（例如 1.7），您还可以在第一行未注释的行中使用以下行开始您的.bashrc和.bash_profile：
# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
(set -o igncr) 2>/dev/null && set -o igncr; # this comment is needed
This will force bash to ignore carriage return (\r) characters used in Windows line separators.
这将强制 bash 忽略\rWindows 行分隔符中使用的回车 ( ) 字符。
See http://cygwin.com/ml/cygwin-announce/2010-08/msg00015.html.

You can also add the option -o igncrto the bash call, e.g.
您还可以将选项添加-o igncr到 bash 调用中，例如
bash -x -o igncr script.sh

The error:
错误：
'\r': command not found
'\r'： 找不到相关命令
is caused by shell not able to recognise Windows-like CRLF line endings (0d 0a) as it expects only LF(0a).
是由 shell 无法识别类似 Windows 的 CRLF 行尾 ( 0d 0a)而引起的，因为它只期望LF( 0a)。
Git
吉特
If you using Git on Windows, make sure you selected 'Checkout as-is' during setup. Then make sure that you run: git config --global core.autocrlf false, so Git will not perform any conversions when checking out or committing text files.
如果您在 Windows 上使用 Git，请确保在安装过程中选择了“按原样结帐”。然后确保您运行: git config --global core.autocrlf false，以便 Git 在检出或提交文本文件时不会执行任何转换。
dos2unix
dos2unix
If you're not using Git, you simply need to convert these affected files/scripts back into Unix-like line endings (LF), either by:
如果您不使用 Git，您只需通过以下方式将这些受影响的文件/脚本转换回类 Unix 行尾 (LF)：
dos2unix ~/.bashrc
Note: The dos2unixcommand is part of dos2unixpackage.
注意：该dos2unix命令是dos2unix包的一部分。
Ex/Vim editor + tr
Ex/Vim 编辑器 + tr
If you've Vim installed, the following command should correct the files:
如果你安装了 Vim，下面的命令应该更正这些文件：
ex +'bufdo! %! tr -d \r' -scxa ~/.bash*
Useful alias: alias dos2unix="ex +'bufdo! %! tr -d \\\\r' -scxa".
有用的别名：alias dos2unix="ex +'bufdo! %! tr -d \\\\r' -scxa".
tr
tr
Here is the method by using tr:
这是使用的方法tr：
cat ~/.bashrc | tr -d '\r' > ~/.bashrc.fixed && mv -v ~/.bashrc.fixed ~/.bashrc
or:
或者：
tr -d '\r' < filename > new_filename
Note: The \ris equivalent to \015.
注意：\r相当于\015。
sed
sed
You can try the following command:
您可以尝试以下命令：
sed -i'.bak' s/\r//g ~/.bash*
recode
recode
The following aliases can be useful (which replaces dos2unixcommand):
以下别名可能很有用（替换dos2unix命令）：
alias unix2dos='recode lat1:ibmpc'
alias dos2unix='recode ibmpc:lat1'
Source: Free Unix Tools (ssh, bash, etc) under Windows.
来源：Windows 下的免费 Unix 工具（ssh、bash 等）。
perl
perl
The following perlcommand can convert the file from DOS into Unix format:
以下perl命令可以将文件从 DOS 转换为 Unix 格式：
perl -p -i.bak -e 's/5//g' ~/.bash*
Source: stripping the ^M.
来源：剥离 ^M。
tofrodos
tofrodos
On Linux, like Ubuntu which doesn't come standard with either dos2unixor unix2dos, you can install tofrodospackage (sudo apt-get install tofrodos), and define the following aliases:
在 Linux 上，像 Ubuntu 一样不带有dos2unix或 的标准unix2dos，您可以安装tofrodos包 ( sudo apt-get install tofrodos)，并定义以下别名：
alias dos2unix='fromdos'
alias unix2dos='todos'
Then use in the same syntax as above.
然后使用与上面相同的语法。
Vagrant

If you're using Vagrant VM and this happens for provisioning script, try setting binaryoption to true:
如果您使用的是 Vagrant VM，并且在配置脚本时会发生这种情况，请尝试将binary选项设置为true：
# Shell provisioner, see: https://www.vagrantup.com/docs/provisioning/shell.html
config.vm.provision "shell" do |s|
s.binary = true # Replace Windows line endings with Unix line endings.
s.path = "script.sh"
