Running a command in the current directory | LinuC Level 1 101 Exam original practice question

1.03.1Basic

Executable check.sh is in the current directory, but that directory is not in PATH.

Which specification runs the file directly?

Hint 1: Focus on the requirement

A slash changes name lookup into explicit path execution; choose the path relative to the current directory.

Hint 2: Key terms

Review the short shell and command-line definitions before comparing the choices.

Relative path: A path interpreted from the current directory or another relative base.
Absolute path: A complete path beginning at the filesystem root.
Current directory: The process directory used as the base for relative paths.
Execute bit: The permission bit needed to run a regular file directly.

Detailed explanation

Incorrectcheck.sh

Incorrect. Without the current directory in PATH, the bare name is not found.

Correct./check.sh

Correct. ./check.sh explicitly starts the lookup in the current directory.

Incorrect/check.sh

Incorrect. /check.sh refers to a file directly under the filesystem root.

Incorrect../check.sh

Incorrect. ../check.sh refers to the parent directory.

An example you can run in a temporary verification environment.

tmp=$(mktemp -d); printf '#!/bin/sh\necho checked\n' >"$tmp/check.sh"; chmod +x "$tmp/check.sh"; (cd "$tmp" && ./check.sh); rm -rf "$tmp"

Foundation review

`./name` explicitly names an entry in the current directory and bypasses PATH lookup.

Verify both the current directory and executable permission before direct execution.
