chdir, fchdir - change working directory


#include <unistd.h> int chdir(const char *path); int fchdir(int fd); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): fchdir(): _BSD_SOURCE || _XOPEN_SOURCE >= 500 || _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L


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.


On success, zero is returned. On error, -1 is returned, and errno is set appropriately.


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_res‐ olution(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 file 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.

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).
