Shell Programming and Scripting

Hi
my file has two columns:

GAII_4:6:100:548:645/1 GTACACAACCCCCCCCCCCCACCCCACCCCCCCCCCCCCC
GAII_4:6:100:1:1242/1 AGTCTGCCCCTCCCCCTNNNNNNNTCTTTTNCCTCCTCCT
GAII_4:6:100:444:504/1 GTAACACACACCCTGATACTCCCCCCTCCACAACCGCTCT

I want to remove the first column and keep only the scond column so it looks like this:

GTACACAACCCCCCCCCCCCACCCCACCCCCCCCCCCCCC
AGTCTGCCCCTCCCCCTNNNNNNNTCTTTTNCCTCCTCCT
GTAACACACACCCTGATACTCCCCCCTCCACAACCGCTCT

Thanks
Joseph
