linux コマンド　cd

ディレクトリの移動を行うためのコマンドです。


bash$ help cd
cd: cd [dir]
    Change the current directory to DIR. 
　　The variable $HOME is the　default DIR. 
　　The variable $CDPATH defines the search path for
    the directory containing DIR.  Alternative directory names are
    separated by a colon (:).  A null directory name is the same as
    the current directory, i.e. `.'.  If DIR begins with a slash (/),
    then $CDPATH is not used.  If the directory is not found, and the
    shell variable `cdable_vars' exists, then try the word as a variable
    name.  If that variable has a value, then cd to the value of that
    variable.
