awk raws without spaces and tabulators at the beginings

[maciekzklanu]

I have to write a AWK program, which write all raws without tabulators and spaces at the beginings of the raws.
here i have my inputs

1 -2 3 -5 2
0 10 -12 -2 3 1
and my outputs:

1 -2 3 -5 2
0 10 -12 -2 3 1


i don't know how to do that..!! please help!!

So, you simply want to strip the leading spaces ?
A simple sed command will do it, but as we are in the awk forum:

awk '{sub(/^[ \t]*/,"");print}' /path/to/input >output

Hope This Helps, PH.
