I’m stuck on “The type builtin: executable files #mg5” challenge
Here are my logs:
[compile] Moved ./.codecrafters/run.sh → ./your_program.sh
[compile] Compilation successful.
[tester::#MG5] Running tests for Stage #MG5 (The type builtin: executable files)
[tester::#MG5] [setup] export PATH=/tmp/baz:$PATH
[tester::#MG5] [setup] Available executables:
[tester::#MG5] [setup] - my_exe
[tester::#MG5] Running ./your_program.sh
[your-program] $ type cat
[tester::#MG5] Output does not match expected value.
[tester::#MG5] Expected: "cat is /bin/cat"
[tester::#MG5] Received: ""
[tester::#MG5] Assertion failed.
[tester::#MG5] Test failed (try setting 'debug: true' in your codecrafters.yml to see more details)

Here is my local output:
$ type cat
cat is /usr/bin/cat
cat: is not a built in
And here’s a snippet of my code:
int check_executable(const char *path){
return access(path, X_OK) == 0;
}
char *find_in_path(char *arguments){
char *path=getenv("PATH");
if(path==NULL){
perror("error not found");
return NULL;
}
char *path_buffer=malloc(sizeof(char)*strlen(path)+1);
strncpy(path_buffer,path,GENERAL_BUFF_SIZE-1);
char *full_path=malloc(sizeof(char)*GENERAL_BUFF_SIZE);
if(full_path==NULL){
perror("error in allocation");
free(path_buffer);
exit(1);
}
char *DIR = strtok(path_buffer,":");
while( DIR != NULL){
snprintf(full_path,GENERAL_BUFF_SIZE,"%s/%s",DIR,arguments);
if(check_executable(full_path)){
free(path_buffer);
return full_path;
}
DIR=strtok(NULL,":");
}
free(path_buffer);
free(full_path);
return NULL;
}
else if(strncmp(input,"type ",strlen("type "))==0){
size_t length=sizeof(built_ins)/sizeof(built_ins[0]);
char *arguments= input+strlen("type ");
char* path=find_in_path(arguments);
if(path){
printf("%s is %s\n",arguments,path);
}
else{
printf("%s is not found\n",arguments);
}
