'\r': command not found - .bashrc / .bash_

Question

I have windows, using Cygwin, trying to set JAVA_HOME permanently through my .bashrc file.

.bashrc:

export PATH="$JAVA_HOME/bin:$PATH"  
export JAVA_HOME=$JAVA_HOME:"/cygdrive/c/Program Files (x86)/Java/jdk1.7.0_05"

.bash_profile:

if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi

running cygwin:

-bash: $'\377\376if': 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.

I've looked at multiple similar questions but I haven't found one where the question has my error exactly.

My home path:

$ echo $HOME
/cygdrive/c/Users/jhsu
$ echo ~
/cygdrive/c/Users/jhsu/

So I believe the files should be placed in the correct spot.

Answer 1

Resolved with Notepad++ :

1) Menu->Edit->EOL Conversion -> Unix/OSX Format

2) Then Save

Fixed

Answer 2

I am using cygwin and Windows7, the trick was NOT to put the set -o igncr into your .bashrc but put the whole SHELLOPTS into you environment variables under Windows. (So nothing with unix / cygwin...) I think it does not work from .bashrc because "the drops is already sucked" as we would say in german. ;-) So my SHELLOPTS looks like this

braceexpand:emacs:hashall:histexpand:history:igncr:interactive-comments:monitor

Answer 3

For the Emacs users out there:

1. Open the file
2. M-x set-buffer-file-coding-system
3. Select "unix"

This will update the new characters in the file to be unix style. More info on "Newline Representation" in Emacs can be found here:

http://ergoemacs.org/emacs/emacs_line_ending_char.html

Note: The above steps could be made into an Emacs script if one preferred to execute this from the command line.

Answer 4

As per this gist, the solution is to create a ~/.bash_profile (in HOME directory) that contains:

export SHELLOPTS
set -o igncr

3. Limitations

You need to use one of supported IDE/editors.

---

4. Argumentation

1. Simply usage. I need set my .editorconfig file 1 time, where I create my project, → I can forget some platform-, style- and IDE-specific problems.
2. Cross-platform, cross-languages, cross-IDE, cross-editors.

5. Example

5.1. Simple

I install EditorConfig plugin for Sublime Text → my text editor. I edit files in Sublime Text.

For example, I have sashacrlf.sh file:

echo "Sasha" &
echo "Goddess!" &

I run this file in Cygwin:

$ bash sashacrlf.sh
Sasha
sashacrlf.sh: line 1: $'\r': command not found
Goddess!

I create a file .editorconfig in same project as sashacrlf.sh.

[*.sh]
end_of_line = lf

It means, that if you save any file with .sh extension in your project in your editor, EditorConfig set UNIX line endings for this file.

I save sashacrlf.sh in my text editor again. I run sashacrlf.sh again:

$ bash sashacrlf.sh
Sasha
Goddess!

I can't get unexpected output in console.

5.2. Multiple file extensions

For example, I want to have UNIX line endings in all files with extensions .sh, .bashrc and .bash_profile. I add these lines to my .editorconfig file:

[*.{sh,bashrc,bash_profile}]
end_of_line = lf

Now, if I save any file with .sh, .bashrc or .bash_profile extension, EditorConfig automatically set UNIX line ending for this file.

Answer 6

For WINDOWS users with Notepad++ (checked with v6.8.3) you can correct the specific file using the option - Edit -> EOL conversion -> Unix/OSX format

And save your file again.

Edit: still works in v7.5.1 (Aug 29 2017)
