Untested, and it depends very much on your shell, but create a function
cdr()
{
cd $1 || exit
if [ -x ./.myscript ]
then
./.myscript
fi
}
Now if you use "cdr" (for Change Directory & Run) it should do what you
want (runs a file called ".myscript" in the new directory if it exists)
This _might_ work...
cd()
{
command cd $1 || exit
if [ -x ./.myscript ]
then
./.myscript
fi
}
OK, I just tested the later under ksh88 and it worked. You'd need to
test with bash/ksh93/whatever-your-shell-is
$ cat x1/.myscript
echo hello
$ cd x1
hello
$ mkdir x0
$ cd x0
$ cd ..
hello
$
As you can see, everytime I enter the "x1" directory it runs .myscript
