Branching on an integer condition | LinuC Level 1 102 Exam original practice question

1.06.2Basic

Print many when count is at least 10.

Use POSIX test integer comparison.

Which condition 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.

test: A command that reports numeric and string conditions through its status.
-ge: The test operator for an integer greater than or equal to another integer.
-le: The test operator for an integer less than or equal to another integer.
-eq: The test operator for two equal integers.
Integer comparison: A comparison of numeric values rather than lexical strings.

Detailed explanation

Incorrectif [ "$count" >= 10 ]; then echo many; fi

Incorrect. [ does not use >= as its integer comparison operator.

Incorrectif [ "$count" -le 10 ]; then echo many; fi

Incorrect. -le tests at most 10, not at least 10.

Incorrectif [ "$count" -eq 10 ]; then echo many; fi

Incorrect. -eq matches only exactly 10.

Correctif [ "$count" -ge 10 ]; then echo many; fi

Correct. -ge tests count greater than or equal to 10.

An example you can run in a temporary verification environment.

sh -c 'count=12; if [ "$count" -ge 10 ]; then echo many; fi'

many
