Search where? In the directory that is your current working directory? In a file hierarchy rooted in your current directory? On the entire system that you're currently logged in to? On a network? Something else???
Can the unknown number of numbers following the leading 'f' be zero?
If you are just looking for one file, what should happen if there is more than one file that meets your criteria?
What operating system and shell are you using?
What have you tried to solve this on your own?

chdir(2) System Calls Manual chdir(2)
Name
chdir - change working directory
Syntax
chdir(path)
char *path;
Description
The path is the pathname of a directory. The system call causes this directory to become the current working directory, which is the
starting point for pathnames that do not begin at the root directory (/).
For a directory to become the current directory, the 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.
Environment
Differs from the System V definition in that ELOOP is a possible error condition.
Diagnostics
The system call fails and the current working directory is unchanged under the following conditions:
[ENOTDIR] A component of the pathname is not a directory.
[ENAMETOOLONG] A component of a pathname exceeds 255 characters, or an entire path name exceeds 1023 characters.
[ENOENT] The named directory does not exist or the path points to an empty string and the environment defined is POSIX or SYS-
TEM_FIVE.
[EACCES] Search permission is denied for any component of the path name.
[EFAULT] The path points outside the process's allocated address space.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EIO] An I/O error occurred while reading from or writing to the file system.
[ESTALE] The file handle given in the argument was invalid. The file referred to by that file handle no longer exists or has been
revoked.
[ETIMEDOUT] A connect request or remote file operation failed because the connected party did not properly respond after a period of
time that is dependent on the communications protocol.
