Oh enlightened monks!
I am trying to use a on liner to extract the first three columns of file1 using the following command 
perl -pane 'print "$F[0]\t$F[1]\t$F[2]";' file1.txt

[download]
But it prints the whole line along with the first 3 columns. 
prints:
chr1    58963   Gchr1    58963   G       G       10      0       10   
+   1       ^+.     8

__file1__
chr1    58963   G       G       10      0       10      1       ^+.   
+  8

How do I fix this? Thanks much!
