使用 cut 重新排列列 [英] Rearrange columns using cut
问题描述
我有以下格式的文件
<前>列 1 列 2字符串 1 1str2 2str3 3我希望重新排列列.我试过下面的命令
<块引用>cut -f2,1 file.txt
该命令不会对列重新排序.知道为什么它不起作用吗?
对于 cut(1)
手册页:
使用 -b、-c 或 -f 中的一种,并且仅使用一种.每个 LIST 由一范围,或多个以逗号分隔的范围.选择的输入被写入与读取顺序相同,并且只写入一次.
它首先到达字段 1,因此打印出来,然后是字段 2.
改用awk
:
awk '{ print $2 " " $1}' file.txt
I am having a file in the following format
Column1 Column2 str1 1 str2 2 str3 3
I want the columns to be rearranged. I tried below command
cut -f2,1 file.txt
The command doesn't reorder the columns. Any idea why its not working?
For the cut(1)
man page:
Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written in the same order that it is read, and is written exactly once.
It reaches field 1 first, so that is printed, followed by field 2.
Use awk
instead:
awk '{ print $2 " " $1}' file.txt
