[SOLVED] sed command to match a pattern and replace it

Issue

I want to use sed command to replace sensitive information in logs with ****. One of the log looks like:

"Log: abcservice : dataUsername generated is = [email protected]\n","stream":"stdout""

The expected output I want is:

"Log: abcservice : dataUsername generated is = ******@as.bbi.co\n","stream":"stdout""

I tried:

sed 's#"dataUsername generated is [[email protected]]"#"dataUsername generated is = ******"#g"

How can I match the pattern "dataUsername generated is = [email protected]" and replace it with "dataUsername generated is = ******@as.bbi.co\n"

Solution

Using sed

$ sed -E 's/(dataUsername generated is = )[^@]*/\1******/' input_file
"Log: abcservice : dataUsername generated is = ******@as.bbi.co\n","stream":"stdout""
