如果你的目录层次很深的话,这个shell会很方便的直接切换到目的目录,例如
当前目录/usr/home,而目录desdir在/usr/home/app/local/opp/william/desdir
直接打入
$ cd desdir,便可直接从当前目录/use/home切换到/usr/home/app/local/opp/william/desdir
配置一下.profile,加入两行
. ./bin/chdir
alias cd='chdir'
file:chdir
# auto find your directory
# Writer: william 2006 beijing
# add the following two line in $HOME/.profile
# . ./bin/chdir
# alias cd='chdir'
chdir(){if [ -z "$1" ] ; then cd PS1="[$PWD]" export PS1; returnelif [ "$1" = - ] ; then cd - PS1="[$PWD]" export PS1; returnelse if [ -d "./$1" ] ; then cd ./$1 PS1="[$PWD]" export PS1; return fifi
for LINE in `find $HOME -type d -print | grep -c \/$1$`
do
if [ $LINE -eq 0 ] ; then
echo "your directory $1 is not exsit($LINE)!"
return
fi
done
for Dir in `find $HOME -type d -print | grep \/$1$`
do
if [ $LINE -gt 1 ] ; then
if [ ! -d "$Dir" ] ; then
echo "$Dir is not a directory"
return
fi
printf "$Dir\t\t...do you want to go? default(y)"
read YESNO
# echo "(y/n)="$YESNO
if [ -z "$YESNO" ] ; then
YESNO=y
fi
case "$YESNO" in
[yY]|[yY][eE][sS])
YESNO=y ;;
[nN]|[nN][oO])
YESNO=n ;;
*)
YESNO="" ;;
esac
if [ "$YESNO" = y ] ; then
cd $Dir
PS1="[$PWD]"
export PS1;
return

continue
