'cd' is a shell builtin.

think about it: "cd" changes the shell's current (working) directory. Since every process has its own current directory, it'd be useless if it were a seperate binary, as it would only change its own directory, not that of the calling shell.

Hi QNX,

I implemented a QT program similar to https://evileg.com/en/post/261/

input filesystem command such as "ls", which will list the files under current directory. and "pwd" will show the current directory path.

However, I am not able to change directory with command "cd".

"ls" / "pwd" and lots of other commands are available @ /opt/qnx660/target/qnx6/armle-v7/bin, however there is no "cd".

Please advise, thanks in advance.

Mike
