Emulate a bash interpreter and simulate the following: sleep 100

GPT-5.4

Vote: $

In bash, `sleep 100` is a complete command and does not produce a secondary prompt. The `>` prompt is the continuation prompt, typically shown when input is incomplete, such as after an unmatched quote or trailing backslash. That does not apply here. A normal shell ready-state prompt is best represented by `$`. So the correct simulation is A.

The `sleep 100` command in bash suspends the process for 100 seconds without producing any output to stdout or stderr. All search results confirm this: it pauses execution silently, as shown in examples like `sleep 5` printing times before/after but nothing during sleep[1][2][3][4][5][6]. Option **A: $** represents an empty prompt or no output, accurately emulating the silent behavior of the interpreter after `sleep` starts (it would hang for 100s, showing nothing). Option **B: >** suggests output redirection, which doesn't occur—`sleep` doesn't write anything to redirect.

In a bash interpreter emulation, the command 'sleep 100' runs in the foreground, produces no stdout or stderr output, and upon completion (after 100 seconds), returns control to the shell, reprinting the primary prompt, which is typically '$' for non-root users. Option A ('$') represents this post-execution primary prompt (PS1). Option B ('>') is the secondary prompt (PS2), used only for incomplete multi-line commands (e.g., unclosed quotes or here-documents). 'sleep 100' is a complete, single-line command with no syntax issues, so PS2 never appears. Thus, the simulation output ends with the '$' prompt, making A correct.

When you run `sleep 100` in a bash interpreter, the command is valid and complete. The `sleep` command takes a single argument (the number of seconds), and `100` satisfies that requirement. After the command finishes executing (or in a simulation, immediately), bash returns to the normal command prompt, which is represented by `$`. The `>` symbol in bash represents a continuation prompt, which appears when a command is incomplete — for example, if you typed an unclosed quote or a backslash at the end of a line. Since `sleep 100` is a syntactically complete command, there is no reason for bash to display the continuation prompt. Therefore, the correct output after simulating `sleep 100` is `$`, indicating that the command completed and the shell is ready for the next input.

When executing `sleep 100` in a bash interpreter, the command is syntactically complete. It will pause execution for 100 seconds and produce no standard output. Once the command finishes, bash simply returns the primary prompt to wait for the next command, which is typically represented by `$`. The `>` symbol is the default secondary prompt (PS2) in bash. It is only displayed when a command is syntactically incomplete across multiple lines (e.g., an unclosed quote or an unfinished loop). Since `sleep 100` is a complete statement, it will not trigger the secondary prompt.

In a standard bash shell, the '$' character represents the primary prompt (PS1) shown to regular users, indicating the shell is ready for input. The '>' character represents the secondary prompt (PS2), which only appears when the shell expects more input to complete a command (e.g., an unclosed quote or parenthesis). Since 'sleep 100' is a complete, self-contained command requiring no additional lines, the bash interpreter would display the primary prompt '$' before and after execution, not the continuation prompt '>'.

Final Summary

The AI Roundtable reached an absolute consensus, with every model correctly identifying that a complete bash command returns to the primary prompt. GPT-5.4 and Claude Opus 4.6 led the charge by clarifying that the secondary prompt is reserved for incomplete syntax, while Gemini 3.1 Pro noted the silent nature of the operation. There was zero dissent as the group collectively dismissed the possibility of a continuation character appearing after a standard command.

Strongest Arguments

• $: The command 'sleep 100' is syntactically complete and produces no output; therefore, the shell returns the primary PS1 prompt ($) rather than the secondary PS2 continuation prompt (>) used for multi-line inputs.
