About checking executable files

[mhk]

Hi ,

i am writing a c language program in Unix to see the executable files in
a directory and it works if the directory is current but if i change to
another directory than current directory then it show all the files even
if not executable.

here is the main code

while (p = readdir(dp))
{
stat(p->d_name, &s);

if (strcmp( p->d_name,".")!= 0 && strcmp( p->d_name,"..")!= 0 )
{
if (s.st_mode & S_IXUSR)
{
cc = ctime(&s.st_mtime);
printf("%s| %s \n", p->d_name, cc);
}
}
}

can anyone help?

Thanks alot.

Try

readdir isn't a standard C library function.

Returns the path relative to the directory being read. Unless that
is the current directory, you're looking for files in the wrong
directory. You have to prefix the directory path to d_name.

# stat(p->d_name, &s);

If you checked the return value and errno of stat, it would be telling
you you've got nonexistent files.
