// SC2130: -e is only valid with 'if' or 'while', not with [ ]
#[allow(unused_imports)]
//
// The -e test flag checks if file exists. In [ ], use -e or -f.
// Don't confuse -e (file exists) with -e shell option (exit on error).
//
// Examples:
// Bad:
// set -e // Shell option (correct context)
// [ -e file ] // File test (correct - this is OK!)
//
// Note: This rule actually flags incorrect usage patterns.
// The -e flag is VALID in [ ] for file tests.
//
// Good:
// [ -e /path/to/file ] // Correct file existence test
// [ -f /path/to/file ] // Correct file test
// set -e // Correct shell option
//
// Impact: Clarification of -e usage contexts
use crate::linter::{Diagnostic, LintResult, Severity, Span};
// NOTE: This rule is actually about detecting misuse of -e in wrong contexts.
// The -e flag is VALID in [ ] for file existence tests.
// We'll check for the shell option usage pattern instead.
pub fn check(source: &str) -> LintResult {
// This rule is tricky - -e is actually VALID in [ ] for file tests
// The issue is when people confuse shell -e option with test -e flag
// For now, we'll skip implementation as the rule description is unclear
// The real issue SC2130 catches is using -e outside of test contexts,
// but -e is primarily a shell option (set -e), not a standalone flag
