I’m stuck on Stage #NI6.
I’ve tried splitting my input, removing space one by one but yet unable to do process what can be a solution.
Why am i getting Quotes in user have not mentioned any single quote already?
Here are my logs:
```auto
remote: [your-program] $ echo 'hello test'
remote: [your-program] hello test
remote: [tester::#NI6] ✓ Received expected response
remote: [your-program] $ echo test shell
remote: [your-program] test shell
remote: [tester::#NI6] Output does not match expected value.
remote: [tester::#NI6] Expected: "test shell"
remote: [tester::#NI6] Received: "test shell"
remote: [your-program] $
remote: [tester::#NI6] Assertion failed.
remote: [tester::#NI6] Test failed
```
And here’s a snippet of my code:
```go
package main
import (
"bufio"
"fmt"
"os"
"os/exec"
"path/filepath"
"strings"
)
func main() {
for {
fmt.Fprint(os.Stdout, "$ ")
in, err := bufio.NewReader(os.Stdin).ReadString('\n')
if err != nil {
fmt.Println(err.Error())
}
in = strings.TrimRight(in, "\n")
cmds := strings.Split(in, " ")
cmds = RemoveSingleQuote(cmds)
switch cmds[0] {
case "exit":
os.Exit(0)
// case "echo":
// cmdsAltered := RemoveSingleQuote(cmds[1:])
// fmt.Println(cmdsAltered)
// // cmds[1] = cmdsAltered
// // fmt.Println(strings.Join(cmds[1:], " "))
case "type":
switch cmds[1] {
case "exit", "echo", "type", "pwd", "cd", "cat":
fmt.Printf("%s is a shell builtin\n", cmds[1])
default:
paths := strings.Split(os.Getenv("PATH"), ":")
isFound := false
for _, path := range paths {
fullPath := filepath.Join(path, cmds[1])
if _, err := os.Stat(fullPath); !os.IsNotExist(err) {
fmt.Printf("%s is %s\n", cmds[1], fullPath)
isFound = true
break
}
}
if !isFound {
fmt.Printf("%s: not found\n", cmds[1])
}
}
case "pwd":
dir, err := os.Getwd()
if err != nil {
fmt.Println("found error in printing directory:" + err.Error())
}
fmt.Println(dir)
case "cd":
if cmds[1] == "~" {
if err := os.Chdir(os.Getenv("HOME")); err != nil {
fmt.Fprintln(os.Stdout, "cd: HOME: No such file or directory")
}
} else if err := os.Chdir(cmds[1]); err != nil {
fmt.Fprintf(os.Stdout, "cd: %s: No such file or directory\n", cmds[1])
}
default:
command := exec.Command(cmds[0], cmds[1:]...)
command.Stderr = os.Stderr
command.Stdout = os.Stdout
if err := command.Run(); err != nil {
fmt.Printf("%s: command not found\n", cmds[0])
}
}
}
}
func RemoveSingleQuote(args []string) []string {
s := RemoveExtraSpace(args)
for i, s := range args {
args[i] = strings.ReplaceAll(s, "'", "")
}
// return strings.Join(s, " ")
return s
}
func RemoveExtraSpace(args []string) []string {
var isFirstSpaceAfterLetter = true
var space = " "
for i, arg := range args {
var ans string
for _, l := range arg {
a := string(l)
if a == space && isFirstSpaceAfterLetter {
// s[i] = l
isFirstSpaceAfterLetter = false
continue
} else if a != space {
isFirstSpaceAfterLetter = true
}
ans = fmt.Sprintf("%s%s", ans, a)
}
args[i] = ans
}
return args
}
```

Hi @ManishBadgotra, the issue stems from here:
The `strings.Split` function is incapable of handling multiple spaces, because it breaks on every space character and creates **multiple empty strings** in the resulting slice.
Let me know if you’d like further clarification.
