1、測試資料

[root@centos7pc1 test2]# cat test.txt
1 x c
2 s d
3 e t
4 d s
5 j u
6 n x

2、程式

[root@centos7pc1 test2]# cat swap.sh
#!/bin/bash
temp1=$(sed -n "$1p" $3)
temp2=$(sed -n "$2p" $3)
sed "$1c $temp2" $3 -i
sed "$2c $temp1" $3 -i

3、測試

[root@centos7pc1 test2]# ls
swap.sh  test.txt
[root@centos7pc1 test2]# cat test.txt    ## 測試資料
 
1 x c
2 s d
3 e t
4 d s
5 j u
6 n x
[root@centos7pc1 test2]# cat swap.sh   ## 程式
#!/bin/bash
temp1=$(sed -n "$1p" $3)
temp2=$(sed -n "$2p" $3)
sed "$1c $temp2" $3 -i
sed "$2c $temp1" $3 -i
[root@centos7pc1 test2]# bash swap.sh 1 3 test.txt   ## 1和3為交換的行號， test.txt為處理的檔案
[root@centos7pc1 test2]# ls
swap.sh  test.txt
[root@centos7pc1 test2]# cat test.txt     ## 檢視交換結果
 
3 e t
2 s d
1 x c
4 d s
5 j u
6 n x

[root@centos7pc1 test2]# ls
swap.sh  test.txt
[root@centos7pc1 test2]# cat test.txt
3 e t
2 s d
1 x c
4 d s
5 j u
6 n x
[root@centos7pc1 test2]# cat swap.sh   ## 程式
#!/bin/bash
temp1=$(sed -n "$1p" $3)
temp2=$(sed -n "$2p" $3)
sed "$1c $temp2" $3 -i
sed "$2c $temp1
 
" $3 -i
[root@centos7pc1 test2]# bash swap.sh 2 5 test.txt   ## 第2行和第5行進行互換
[root@centos7pc1 test2]# ls
swap.sh  test.txt
[root@centos7pc1 test2]# cat test.txt    ## 檢視交換結果
3 e t
