cd - Change working directory








cd ?dirName?










Change the current working directory to dirName, or to the
    home directory (as specified in the HOME environment variable) if
    dirName is not given. Returns an empty string. Note that the current
    working directory is a per-process resource; the cd command changes
    the working directory for all interpreters and (in a threaded environment)
    all threads.








Change to the home directory of the user fred:






cd ~fred




Change to the directory lib that is a sibling directory of
    the current one:






cd ../lib










filename(3tcl), glob(3tcl), pwd(3tcl)
