To identify and substitute a semantic version within a document using sed, you can use the following command:

sed -i 's/\b[0-9]\+\.[0-9]\+\.[0-9]\+\b/<new_version>/g' <filename>

This command will search for any occurrence of a semantic version (in the format of x.y.z) within the specified file and replace it with the <new_version> value provided. The -i option is used to edit the file in place.

For example, if you want to replace all occurrences of version 1.2.3 with 2.0.0 in a file named example.txt, you would use the following command:

sed -i 's/\b1\.2\.3\b/2.0.0/g' example.txt

This command will find and replace all instances of 1.2.3 with 2.0.0 in the example.txt file.
