linux如何实现两个字符串相互替换

echo `echo AA BB CC DD|sed -e 's/AA/@@/g'|sed -e 's/CC/AA/g'|sed -e 's/@@/CC/g'`

先把AA替换成@@ 然把CC替换成AA 再把@@替换为CC@@起中转的作用

root@localhost:~# echo enable="true",url="http://10.25.136.232",showSlider="true",

enable=true,url=http://10.25.136.232,showSlider=true,

root@localhost:~# echo enable="true",url="http://10.25.136.232",showSlider="true",|sed 's@url=".*",s@url="https:\/\/test.com",s@g'

enable=true,url=http://10.25.136.232,showSlider=true,
