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. CONFORMING TO top POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD. NOTES top 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).

I'm reading from user and find out if he is using "cd". I always get an error. What am I doing wrong? Code: int * status=0; char * buf = 0; char arguments[2048]; buf = getcwd(buf,PATH_MAX); printf("%s >",buf); fgets(arguments,2048,stdin); if( strncmp(arguments,"quit",4)==0 ){ printf("Exit...\n"); break; } else if(strncmp(arguments,"cd",2)==0 ){ int ret; printf("\nGOT = %s\n",(arguments+2)); ret = chdir ((arguments+2)); if(ret!=0){ perror("Error:"); } } c linux console chdir share|improve this question edited http://stackoverflow.com/questions/16376892/c-using-chdir-function Apr 7 '15 at 3:57 Jonathan Leffler 438k61509822 asked May 4 '13 at 17:12 Jumpy_Goat 320825 3 ... and that error would be what, exactly? –paxdiablo May 4 '13 at 17:17 GOT = /home Error:: No such file or directory –Jumpy_Goat May 4 '13 at 17:24 That'll be a newline at the end of the input, see my answer. –paxdiablo May 4 '13 at 17:26 1 BTW, you could use strace and gdb to debug your issue. That would be faster than asking here.... –Basile Starynkevitch May 4 '13 at 17:46 1 Study the source code of some small free software shell like sash –Basile Starynkevitch May 4 '13 at 17:56 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted If the line being entered is something like: cd xyzzy then the directory starts at offset 3, not 2. In addition, fgets usually gives you a line with a newline character at the end so you'll want to remove that as well, such as: if (strlen (line) > 0) if (line[strlen (line) - 1] == '\n') line[strlen (line) - 1] = '\0'; You should probably be tokenising the input a little more intelligently, a shell like bash (for example) has rather complex rules. shar
is usually included automatically. Description: The chdir() function http://www.qnx.com/developers/docs/6.5.0SP1.update/com.qnx.doc.neutrino_lib_ref/c/chdir.html changes the current working directory to path, which can be relative to the current working directory or an absolute path name. Returns: 0 Success. -1 An error occurred (errno is set). Errors: EACCES Search permission is denied for a component of path. EINTR The call was error c interrupted by a signal. ELOOP Too many levels of symbolic links or prefixes. ENAMETOOLONG The path argument is longer than PATH_MAX, or a pathname component is longer than NAME_MAX. ENOENT The specified path doesn't exist, or path is an empty string. ENOMEM There wasn't enough chdir error c memory to allocate a control structure. ENOSYS The chdir() function isn't implemented for the filesystem specified in path. ENOTDIR A component of path is not a directory. Examples: #include
