如何用 sed 替换一行 /

Question

您好，我目前有一个这种格式的文件：

This  is a test file

location = /home/files

我的问题是如何用 location = /home/documents/test_files 替换这一行 location = /home/files？

Answer 1

当原始字符串或替换字符串中有“/”时，我们想用“\”转义“/”。或者，您可以使用任何字符作为替换分隔符，例如“@”

$ cat sample.csv 
This  is a test file

location = /home/files

$ sed 's@/home/files@/home/documents/test_files@' sample.csv 
This  is a test file

location = /home/documents/test_files

Answer 2

只需选择不同的分隔符：

sed 's-location = /home/files-location = /home/documents/test_files-' test.txt
sed 's~location = /home/files~location = /home/documents/test_files~' test.txt

或者转义 /:

sed 's/location = \/home\/files/location = \/home\/documents\/test_files/' test.txt
