How to merge two lines in Linux into one line?

In a Linux system, if you want to merge two lines into one, you can use the following method:

1. Connect commands using a backslash (\): add a backslash (\) at the end of the first line and continue with the command at the beginning of the second line. This will make the two lines of commands be considered as one line.

command1 \
command2

1. Use a semicolon (;) as a separator: by using a semicolon to separate two commands, they will be interpreted as one line of code.

command1; command2

1. Use the double pipe (||) logical operator: To ensure that the second command is only executed after the successful execution of the first command, use the double pipe operator.

command1 || command2

In the first and second methods, both commands will be executed sequentially; however, in the third method, if the first command fails (returns a non-zero exit status code), then the second command will be executed.
