Selecting Bash for a directly executed script | LinuC Level 1 102 Exam original practice question

1.06.2Basic

Execute a permissioned script directly as ./report.sh.

Use Bash syntax by naming the interpreter on the first line.

Which first line is appropriate?

Hint 1: Focus on the input model

Separate word-list iteration, condition-controlled loops, field splitting, and literal input handling before comparing the choices.

Hint 2: Key terms

Review the short definitions of the shell syntax, parameters, permissions, and control flow involved.

Shebang: The first script line that selects the interpreter used for direct execution.
#!: The two-character marker at the start of an interpreter directive.
/bin/bash: A common filesystem path for the Bash executable.
Execute permission: The mode bit required to launch a file directly as a command.
Interpreter: A program that parses and runs script source text.

Incorrect#/bin/bash

Incorrect. Without !, this is an ordinary comment.

Incorrect#!bash /bin

Incorrect. A shebang expects the interpreter path immediately after #!.

Correct#!/bin/bash

Correct. /bin/bash is specified as the script interpreter.

An example you can run in a temporary verification environment.

bash --noprofile --norc -c 'f=$(mktemp); printf "#!/bin/bash\nprintf \"%s\\n\" bash-ok\n" >"$f"; chmod +x "$f"; "$f"; rm -f "$f"'
