How Linux quickly switches to a directory

Often use the CD command to switch directories, although there are CDs-, historical directory pop push operation, after all, not intuitive. Directly on the code and deployment:

I=1here= ' pwd ' valid_here=${here//\//\\\/}already_exist= ' grep ^${here}$ $1 ' declare -a  godirswhile true; do  [[ $2 =  "a"  ]] && [[ x${ already_exist} =  "x"  ]] && sed -i  "/^eof/i\\${here}"  $1    [[ $2 =  "A"  ]] && break  [[ $2 =  "D " ]] && [[ x${ALREADY_EXIST} != " x " ]] && sed  -i  "/^${valid_here}$/d"  $1  [[ $2 =  "D"  ]] &&  break  while true ; do    read line         if [ $? -ne 0 ] ; then         break    fi    [[ -d  $line  ]]  | |  continue    echo -e  "\033[' expr 35 +  $i  % 3 ' m"   $i:  $line     godirs[$i]= $line     let i= $i +1  done <<- eof/usr/localeof# ===== end of here-document =====echo -e  "\033[0m" Echo  -n  ' where to go?  ' read -n1 -t30 necho[[ x${godirs[${n}]} !=   "X"  ]] && cd ${godirs[${n}]}breakdone

Put this file in a directory, such as/path/ff

Add a row in ~/.BASHRC

Alias Ff= '. /path/ff Path/ff '

You can use it to log out again.

Here's how to use it:

# ff# FF a# FF D

Switch directories, add directory indexes, delete directory indexes, respectively
