[Solved] How to separate one line to mutiple line based on certain number of characters?

hi Gurus,

I need separate a file which is one huge line to multiple lines based on certain number of charactors. for example:
Code:
abcdefghi high abaddffdd

I want to separate the line to multiple lines for every 4 charactors.
the result should be
Code:
abcd
efgh
i hi
gh a
badd
ffdd

Thanks in advance.

With awk
Code:
awk '{for (i=1;i<=length($0);i+=4) print substr($0,i,4)}' file

For completeness:
Code:
sed 's/.\{4\}/&\
/g' file

Yes, sed needs two lines. GNU sed also takes one line with \n.
