I want to change FS in awk, but not in BEGIN. I want to print word and the letter.
awk 'BEGIN{FS=""}{print $1; FS=" ";print $1; FS=""}'
Of course it does't work. Is there any function, way to show words's letters?

1Could you give a sample input and desired output? What exactly are you trying to do? Would multiple field separators do the job? What should an empty FS do?– FelixJNAug 24, 2015 at 9:23

I found solution couple minutes ago. I use "split()" function.– diego9403Aug 24, 2015 at 17:52

awk is record oriented. It won't allow resetting the FS while processing the same line. Judging from the code you've written, you would like to take, e.g., this input:
First
Second
and you would want to see as output:
F
First
S
Second
One way to do that with awk:
awk '{print substr($1,1,1) ; print $1}' inputfile
F
First
S
Second
