You want to redirect the output of several commmands at once to a file called "collect". You want to collect the output of the "id" command and the "ls -l" commands for both your home directory and the /bin directory to this file. Of the choices below, which command will accomplish your task? Choose only one answer.

1. (id ; ls -l ~ ; ls -l /bin) > collect
2. (id : ls-l ~ : ls -l /bin) > collect
3. [id . ls-l ~ . ls -l /bin] > collect
4. {id \ ls-l ~ \ ls -l /bin} > collect
5. ((id : ls -l ~ : ls -l /bin)) > collect
6. {id ; ls -l ~ ; ls -l /bin} > collect

Answer later.

 

If you mean all the brackets, when you want to run multiple commands in a single shell, you have to contain them. Your job is to determine which command syntax is correct to accomplish the stated goal. Good luck, AJ.

 

Answer time. The correct answer is #1. If you want to process several commands at the same time and redirect them to the file "collect", all of the commands must be contained in parenthesis and each command must be separated by a semi-colon.
