# Add blank line before end of file with export

I have a list of points (e.g. {1.2,0.4}) which I export to a file using

Export[fileName, list];


I want to add a line before the end of file. For instance instead of ending the file with

1.236677 4.64567567
1.236677 4.64567567
1.236676 4.64567567


ending like

1.236677 4.64567567
1.236677 4.64567567
1.236676 4.64567567
# a blank line here


I tried appending {}, {,}, "" to the list, but none of them added a blank line.

I need this because xmgrace is not parsing the last line of the exported mathematica file: it expects a blank line before the End of File.

EDIT: As pointed out in the comments by Kuba and Pinguin Dirk, appending "" works on Windows XP (and probably others.) I'm using OS X.

maybe something like: Export["foo.txt", Append[list, ""]]? –  Pinguin Dirk Sep 11 '13 at 9:41
I already tried that but it doesn't work. If I use " ", it prints a new line with a white space in it. –  J. C. Leitão Sep 11 '13 at 10:10
@J.C.Leitão What OS are you working on? Pinguin Dirk's solution works on WinXP. –  Kuba Sep 11 '13 at 10:22
If all else fails: file=OpenAppend["file"]; Write["\n"]; Close[file] –  Pickett Sep 11 '13 at 10:50
@cormullion, yep, OS X here too, and I too tried "\n". What file type are you exporting to? –  Pinguin Dirk Sep 11 '13 at 12:20

Here, on my OSX the following works

Export["tmp/foo.txt", Append[Range[10], "\n"]]

Try

Export[fileName, Append[list, ""], "Table"]


This should be OS-independent although I cannot check this under OS X.

Doesn't work with OSX. At least on my 9.0.1 with OSX 10.8.4 –  halirutan Sep 11 '13 at 13:30
