shell script replace variable of linux path
sed is a popular tool to be used to replace a string in a file.
For example, give a file, we can use the following command to replace all the string XXX into YY
sed -i s/XXX/YY/g fileName
or sed s/XXX/YY/g fileName > newFile
but when you want to replace linux path, the above method doesn’t work. You can try it your self.
here is a workable solution:
sed “s,$pathA,$pathB,g” fileName > newFileName
then all the path of /user/xx/zz/ will be replaced by /user/aa/zz/dd.
It turned out, you can also change , to other characters such as #, ctr-A, et al,
as long as the variables don’t contain the separator, it will work.
