only for bash (not for csh, ksh, ...)
a command for quick navigation to some dirs (specified in Table) and last 10 visited dirs

1. config
in ~/.bashrc
add:
 export DIR_GT="$HOME/script/GoTo"  #this directory
 alias gt=". $DIR_GT/gt_root.sh"
 . $DIR_GT/bashrc_gt

2. usage
a. mkdir sure $DIR_GT/Tables/default.tbl exist (if not exist, touch it; you can clear its content, because I put mine directories in it)
b. gt  #view the dir list (from current table) and navigate
c. gt -addwd  #add current workding dir to current Table
d. gt -cdtable #goto $DIR_GT/Tables/, can mannually add a table
e. gt -new x.tbl  #new table 
f. gt -load x.tbl  #load a table (replace default.tbl)
g. gt -reset  #i.e. gt -load default.tbl
h. gt x.tbl  #gt, but with x.tbl (temporarily switch a table, just for this gt comamnd)
i. gt -h #help
