CD SPACE

Tail notes

The Cd_func there is a small problem, when using the CD without parameters, the CD will be executed, the dirname $1 command to execute the dirname (no parameter) will be the first help information, but in the script will not prompt, so in terms of use should still live, if the obsessive-compulsive friends can change their code;
PS: Can't Lose is

if [ "x"$1 != "x" && -f $1] ;then     cd `dirname $1` else    cd [email protected]fi
