Converting newline formatting from Mac to Windows
Windows uses carriage return
+ line feed
for newline:
\r\n
Unix only uses Line feed
for newline:
\n
In conclusion, simply replace every occurence of \n
by \r\n
.
Both unix2dos
and dos2unix
are not by default available on Mac OSX.
Fortunately, you can simply use Perl
or sed
to do the job:
sed -e 's/$/\r/' inputfile > outputfile # UNIX to DOS (adding CRs)
sed -e 's/\r$//' inputfile > outputfile # DOS to UNIX (removing CRs)
perl -pe 's/\r\n|\n|\r/\r\n/g' inputfile > outputfile # Convert to DOS
perl -pe 's/\r\n|\n|\r/\n/g' inputfile > outputfile # Convert to UNIX
perl -pe 's/\r\n|\n|\r/\r/g' inputfile > outputfile # Convert to old Mac
Code snippet from:
http://en.wikipedia.org/wiki/Newline#Conversion_utilities
Just do tr
delete:
tr -d "\r" <infile.txt >outfile.txt
You can install unix2dos with Homebrew
brew install unix2dos
Then you can do this:
unix2dos file-to-convert
You can also convert dos files to unix:
dos2unix file-to-convert
This is an improved version of Anne's answer -- if you use perl, you can do the edit on the file 'in-place' rather than generating a new file:
perl -pi -e 's/\r\n|\n|\r/\r\n/g' file-to-convert # Convert to DOS
perl -pi -e 's/\r\n|\n|\r/\n/g' file-to-convert # Convert to UNIX
