NAME

       chdir, fchdir - change working directory

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <unistd.h>

       int chdir(const char *path);
       int fchdir(int fd);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fchdir():
           _XOPEN_SOURCE >= 500
               || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
               || /* glibc up to and including 2.19: */ _BSD_SOURCE

DESCRIPTION

       chdir()  changes  the  current  working  directory of the calling process to the directory
       specified in path.

       fchdir() is identical to chdir(); the only difference is that the directory is given as an
       open file descriptor.

RETURN VALUE

       On  success, zero is returned.  On error, -1 is returned, and errno is set to indicate the
       error.

ERRORS

       Depending on the filesystem, other errors can be returned.  The more  general  errors  for
       chdir() are listed below:

       EACCES Search  permission  is  denied  for  one  of  the  components  of  path.  (See also
              path_resolution(7).)

       EFAULT path points outside your accessible address space.

       EIO    An I/O error occurred.

       ELOOP  Too many symbolic links were encountered in resolving path.

       ENAMETOOLONG
              path is too long.

       ENOENT The directory specified in path does not exist.

       ENOMEM Insufficient kernel memory was available.

       ENOTDIR
              A component of path is not a directory.

       The general errors for fchdir() are listed below:

       EACCES Search permission was denied on the directory open on fd.

       EBADF  fd is not a valid file descriptor.

       ENOTDIR
              fd does not refer to a directory.

STANDARDS

       POSIX.1-2008.

HISTORY

       POSIX.1-2001, SVr4, 4.4BSD.

NOTES

       The current working directory is the starting point for  interpreting  relative  pathnames
       (those not starting with '/').

       A  child process created via fork(2) inherits its parent's current working directory.  The
       current working directory is left unchanged by execve(2).
