What is semicolon in shell script?
A semicolon or ampersand ( ; or & ) in a shell script is a command terminator.

A newline in a shell script is a “weak” command terminator.

Which is stronger a semicolon or a period?
Remember, semicolons are not interchangeable with commas or periods. Instead, they’re somewhere in between: stronger than a comma but not quite as divisive as a period. Sounds pretty cunning to us. Here are the rules for using semicolons correctly; we hope you’re taking notes.
