Difference between single ampersand and double ampersand? [duplicate]
By Sarah Rodriguez •
I know some people have asked about the difference between a semicolon and double ampersand to chain commands.
But what I see in this file from SQL Server Docker, is SINGLE ampersand.
What does it mean?
What's the difference between these two lines of codes:
/opt/mssql/bin/sqlservr & /usr/src/app/import-data.sh & npm start
/opt/mssql/bin/sqlservr && /usr/src/app/import-data.sh && npm start
