  • How to escape single quotes within single quoted strings? 19 answers

    • Use double-quotes around sed for variable expansion & to preserve single quotes. 

    sed -i "s/os.path.join(BASE_DIR, 'db.sqlite3'),/$project_name,/g" "$project_name/settings.py"

    tested working fine on GNU sed version 4.2.1

    You should escape the quotes in 'db.sqlite3' : 

    sudo sed -i 's/os.path.join(BASE_DIR, '''db.sqlite3'''),/'$project_name',/g' $projects_name/settings.py

    Your sed pattern is os.path.join(BASE_DIR, db.sqlite3), because quotes in 'db.sqlite3' are not interpreted as literal ' . Instead they close and reopen the sed command.
