Sorry, yes I kind deleted the output.txt.
This is the out come after apply this sed commad to input.txt.

sed '/[[:digit:]]/d' input.txt > output.txt

The result of output.txt is still nothing inside.


Code:
Untitleds-MacBook-Pro:Documents Nexeu$ ls -l *put.txt; echo 'input:'; cat input.txt; echo; echo 'output:'; cat output.txt
-rw-r--r--@ 1 Nexeu  staff  17639800 Feb 11 23:53 input.txt
-rw-r--r--  1 Nexeu  staff         0 Feb 12 17:00 output.txt
input:
9DCGA8D
A88GDCF8
output:
Untitleds-MacBook-Pro:Documents Nexeu$

The output.txt is blank as usual and nothing is inside.

If the characters are non-printable, what are the options I have to fix this? In the input.txt, there's only A-Z and 0 8 9 characters, no any other special characters. Smilie

I'm using Mac Os X Yosemite Ver 10.10.2 (14C109) btw
