Mac Convert Line Endings For Unity
Unity is the ultimate game development platform. Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR, consoles or the Web, and connect with loyal and enthusiastic players and customers. Some are Mac OS X (UNIX) and some are Windows. Many text editors can fix this using Convert Line Endings menu commands. I keep getting.

There's a very nice utility developed by Josh Aas called 'LineBreak' that handles this nicely via GUI, including drag-n-drop:
'This is a simple utility for Mac OS X that converts line breaks in text documents'
It's GPL'd, and can be found at <http://www.macalester.edu/~jaas/linebreak.html>
So, what do I do with the downloaded flip.osx file?

I'll assume a little Unix and CLI knowledge -- if not, this may not be a very useful command for you.
1. Download the file with a Command-click (to make sure binary will work properly).
2. Start a terminal and move the file to the directory where you keep any other Unix commands. You can also drop the '.osx' and
rename it if you wish.
3. Change permissions to allow users to execute flip.osx ('chmod 555 flip.osx' should do it).
4. Type 'rehash' and try it out with the '-t' option. If it doesn't work, double check your permissions and whatnot.

cat $1 tr 'r' 'n'To convert unix files to Mac files, here is 'unix2mac':
cat $1 tr 'n' 'r'To convert DOS files to unix files, here is 'dos2unix':
cat $1 tr -d 'r'These employ the 'tr' (translate character) utility.
Need double-backslashes in this website (one gets
eaten by the remove slashes step, after previewing;)
I got bitten by that too; Larry.
the freeware TextExtras provides an service-menu for line-ending-conversion. like all services its available in all cocoa-text-fields.
In the following example we have just read the contents of a file and put it into fContents.
-- first we ask to put all the lines into a list (fParagraphs). AppleScript doesn't care if it is Unix, Mac or Windows.
set fParagraphs to paragraphs of fContents-- now we tell AppleScript that lists will be concatenated using return characters when the list is converted to a string (Mac). This could also be 'n' for newline (UNIX), 'rn' for character return+new line (Windows) or 'r' for character return (Mac). Don't be alarmed when you compile the script and see that r and n has changed into line breaks. The script still know that they are two different characters.
set AppleScript's text item delimiters to return-- here we convert the list of paragraphs to strings using the text item delimiters
set fContentsNew to fParagraphs as string-- here we reset the text item delimiters to ' which is default.
set AppleScript's text item delimiters to '
You can download the package from here:
ftp://us.osxgnu.org/pub/osxgnu/File_utils/unix2dos-1.2X.pkg.sit
USAGE: dos2unix [file ..]
DESCRIPTION
When called whithout parameters, the dos2unix utility reads from the standard input, transforming CR/LF pairs into an
LF character and writing it to the standard output. If there's at least one filename specified, the file operands are
processed in command line order, reading from the files specified and overwriting them with the converted version.
It's important to note that the dos2unix utility is the same program as the unix2dos(1) utility. It simply checks its name
to see what operation is expected. If you change the name of the binary, dos2unix will default to converting files from
UNIX to DOS.
#!/bin/sh
zip -qr foo.zip '$@' && unzip -aqo foo.zip && rm foo.zip
And then execute it as:
fixascii [files or directories to convert]
Which has the benefit over most of these other commands in that you can point it with impunity at an entire directory tree and it will process all the files in it and not corrupt any binaries that may happen to have a string of bits in them that look like a line-ending.
I've seen too many times where someone corrupted a ton of images and other binaries, when trying to fix line-endings on text files using dos2unix or tr in combination with find but failed to ensure that only text files were processed. Unzip figure out which files are ascii, converts them, and leaves the binaries alone.
BTW, it's the '-a' flag to unzip, that is causing the ascii files to have their lines endings converted.
Thanks! Couldn't resist optimizing this one a bit, though. :)
zip -qr0 foo.zip '$@' && unzip -aqo foo.zip && rm foo.zip
which does no compression and presumably will take less CPU time. Of course it requires more disk space..
I thought about factoring out the foo.zip into a variable but am too rusty in sh/bash syntax and have already spent too much time skimming through the bash man page. :)
I also thought about generating a (hopefully)-guaranteed unique temp filename rather than using foo.zip as is. I think you do that with $$ or similar.
Note: This document is primarily concerned witholder systems and text files, and does not factor in Unicode or wordprocessed files.
Traditionally, Unix and Mac OS differ in theformat in which they store text files. Mac OS places a carriagereturn character at the end of each line of a text file, but Unix usesa line feed character. Some Unix applications won't recognize thecarriage returns added by Mac OS, and will display a file as a singleline, interspersed with Ctrl-m characters. This appearson the screen as ^M. Similarly, some Mac OS applicationsneed to see carriage return characters at the ends of lines, and maytreat Unix-format files as one long line.
In Mac OS X, the situation is more complicated. BecauseMac OS X is a meld of Unix and the older Mac OS, in some cases textfiles have carriage returns and in others they have line feeds. Forthe most part, classic applications still require text files to havecarriage returns, while the command-line Unix utilities require linefeeds. Mac OS X-native applications are usually capable ofinterpreting both.
There are many ways to resolve the differences in format. In thisdocument you will find instructions on how to use the Unix commandline utilities tr, awk, and Perl todo the conversion. From Mac OS X, each can be accessed from theTerminal application.
tr
The Unix program tr is used to translatebetween two sets of characters. Characters specified in one set areconverted to the matching character in the second set. Thus, toconvert the Ctrl-m of a Mac OS text file to the line feed(Ctrl-j) of a Unix text file, at the Unix command line,enter:
Here, r and n are special escapesequences that tr interprets as Ctrl-m (acarriage return) and Ctrl-j (a line feed), respectively.Thus, to convert a Unix text file to a Mac OS text file, enter:
Note: The escape sequences must be surrounded bysingle quotation marks for these commands to work.
awk
To use awk to convert a Mac OS file to Unix, at theUnix prompt, enter:
To convert a Unix file to Mac OS using awk, at thecommand line, enter:
On some systems, the version of awk may be old and notinclude the function gsub. If so, try the same command,but replace awk with gawk ornawk.
