Some questions
Are you looking for the file which has the most resent filename?
-- If so you can use the sort command, like `ls -1 | sort`
Are you looking for the file which is most resent touched (writing in the file)?
-- If so you can use the ls command, like `ls -rt1 | tail -1`
take care

CHDIR(2) BSD System Calls Manual CHDIR(2)
NAME
chdir, fchdir -- change current working directory
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
chdir(const char *path);
int
fchdir(int fd);
DESCRIPTION
The path argument points to the pathname of a directory. The chdir() function causes the named directory to become the current working
directory, that is, the starting point for path searches of pathnames not beginning with a slash, '/'.
The fchdir() function causes the directory referenced by fd to become the current working directory, the starting point for path searches of
pathnames not beginning with a slash, '/'.
In order for a directory to become the current directory, a process must have execute (search) access to the directory.
RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.
ERRORS
chdir() will fail and the current working directory will be unchanged if one or more of the following are true:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG] A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters.
[ENOENT] The named directory does not exist.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EACCES] Search permission is denied for any component of the path name.
[EFAULT] path points outside the process's allocated address space.
[EIO] An I/O error occurred while reading from or writing to the file system.
fchdir() will fail and the current working directory will be unchanged if one or more of the following are true:
[EACCES] Search permission is denied for the directory referenced by the file descriptor.
[ENOTDIR] The file descriptor does not reference a directory.
[EBADF] The argument fd is not a valid file descriptor.
[EPERM] The argument fd references a directory which is not at or below the current process's root directory.
SEE ALSO
chroot(2)
STANDARDS
The chdir() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
HISTORY
The fchdir() function call appeared in 4.2BSD.
BSD
December 11, 1993 BSD
