here you arecut -f1 -d' ' sourcefile > tmpfile1
cut -f2 -d' ' sourcefile > tmpfile2
cut -f3-x -d' ' sourcefile > tmpfile3
paste tmpfile2 tmpfile1 tmpfile3 > tmpfile4
sed 's/\t/ /g' < tmpfile4 > resultfile
FYI: the x in the 3rd command should be the total column# of that file.

哦，忘记了rolia不支持这个符号\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\，最后一句显示错误了，反正最后你把tmpfile4，里面的tab分隔符号，变成空格就ok了

awk '{ printf "%s %s", $2, $1; for (i=3; (i <=NF); i+=1) {printf " %s", $i} print "" }' filename > new_filename
