如何使用/替换带有sed的行

Question

您好我目前有这种格式的文件：

This  is a test file

location = /home/files

我的问题是如何将此行location = /home/files替换为此location = /home/documents/test_files？

Answer 1

如果原始字符串中有“/”或替换字符串，我们会使用“\”来转义“/”。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

或逃避/：

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