Unix cut/code> 指挥权包括一个领域清单,但不是我所需要的命令。
$ echo 1,2,3,4,5,6 | cut -d, -f 1,2,3,5
1,2,3,5
$ echo 1,2,3,4,5,6 | cut -d, -f 1,3,2,5
1,2,3,5
然而,我要按照我具体规定的顺序,向我提供的“九星”指挥。
使用:
pax> echo 1,2,3,4,5,6 | awk -F, BEGIN {OFS=","}{print $1,$3,$2,$5}
1,3,2,5
或
pax> echo 1,2,3,4,5,6 | awk -F, -vOFS=, {print $1,$3,$2,$5}
1,3,2,5
或者仅仅使用炮弹
$ set -f
$ string="1,2,3,4,5"
$ IFS=","
$ set -- $string
$ echo $1 $3 $2 $5
1 3 2 5
以家庭为基础的解决办法是有害的。 这里的解决办法是:
echo 1,2,3,4,5,6 | perl -e @order=(1,3,2,5);@a=split/,/,<>;for(@order){print $a[$_-1];}
