Question

How can we specify more than one command in the command line at the same time?

(a) using ;

(b) using >

(c) using ==

(d) not possible

This question was addressed to me during an internship interview.

My doubt is from Commands in section The Unix Architecture & General Purpose Utilities of Unix

Answer 1

Correct option is (a) using ;

The best I can explain: UNIX allows us to specify more than one command at the same time in the command line. To do so, we have to separate each command from each other using (;). For example, wc file1 ;     ls  -l file1 . The > symbol allows us to redirects the output of the command(s). For example, wc file1 > file2. Now, file2 will contain the output produced by the wc file1 command. Both ; and > are called metacharacters.
