silly problem

[kapat]

i use debian unstable. here's the silly problem
1. no manpages for cmds like 'cd' 'exec' etc ...

2. i have an executable file, named 'mycd', in my PATH which contains just the following one line ..

cd /tmp

obviously, the goal is to change the directory to /tmp and BE THERE when i execute mycd command. but it runs a child process, goes to that directory (/tmp), completes and exits the child process and gets back to $PWD. i don't want that. so any way out ?? i could run mycd by 'sourcing' it :

. mycd

and achieve the desired goal, but i dont want to do that.

u might question why at all ? well the actual requirement is not this stupid. its a small part of a bigger and different goal.

Then it has to cd to /tmp before it runs the child process.

1. 'cd' and 'exec' are commands that are built-in to the shell. If you run the man pages on bash, it'll help you figure that out. As I'm on a Windows machine at this time, I don't know the command off the top of my head but try "bash -c help"

2. The shell will always fork and exec a whatever it needs to run. If you don't want this happening, then just run "exec" followed by whatever you are running.
