pipe-exit

This script reads all data from its standard input (stdin). If any data is received, it sends that data to standard output and exits with a status code of 1 (indicating failure). If no data is received, it sends nothing to stdout and exits with a status code of 0 (indicating success).

• Exit Code 0: Success (no input received)
• Exit Code 1: Failure (input received and passed through)
• Exit Code 2: Internal error during stream processing

Usage:

your_command_expression 2>&1 | pipe-exit

Examples

Success - no output from 'true'

• true 2>&1 | pipe-exit
• Expected output: (nothing)
• Expected exit code: 0

Failure - output from 'echo'

• echo "Error message here" 2>&1 | pipe-exit
• Expected output: "Error message here"
• Expected exit code: 1

Failure - output from 'ls' in case of error

• ls non_existent_file 2>&1 | pipe-exit
• Expected output: (ls error message)
• Expected exit code: 1
