Hello,
I need to write out a text file with variable length lines and no trailing
spaces. I can do it externally with sed but I'd prefer do it the J way.
However, I can't figure it out. Any help would be greatly appreciated.

require '~addons/general/misc/format.ijs'
1!: 44 'c:/temp'
]rows=:4 1 $;:'one two three four' NB. the real file is a .csv from Excel

|one |

|two |
+-----+
|three|

|four |

(,"2>rows) fwrites 'testfile'

NB. test file has unwanted trailing spaces
hexdump shell 'type testfile'
00 6F 6E 65 20-20 0D 0A 74 77 6F 20 20-0D 0A 74 68 |one ..two ..th|
10 72 65 65 0D-0A 66 6F 75 72 20 0D 0A |ree..four .. |
NB. desired result
hexdump shell 'sed ''s/ *$//'' testfile'
00 6F 6E 65 0D-0A 74 77 6F 0D 0A 74 68-72 65 65 0D |one..two..three.|
