"home" is shorter than "cd"?
And how does a child process affect its parent's environment?
String constants like "/home/" aren't guaranteed to be in writable memory. If it is, you've just trashed whatever followed it. You want this:
char * base = new char[name_len + 7]; strcpy( base, "/home/" ); strcat( base, name );
But wait...what is the point of the "name" variable?
char * base = new char[name_len + 7]; strcpy( base, "/home/" ); strcat( base, login_name );
Or, doing this right and using std::string:
std::string base = "/home/" + std::string(getlogin());
> FILE* bong; > std::cout<<"going to home directory...\n"; > bong = popen(base,"w");
Oops. You left out the "cd". Change "/home/" in the earlier stuff to "cd /home/".

After you build this and it doesn't work, and you finally figure out why, you will feel really dumb. However, don't feel bad. Dennis Ritchie made the same mistake when he implemented the "cd" command way back on the earliest Unix that had a shell and a filesystem with directories. :-)

This has got to be a joke.
On every nix box I have ever seen, simply entering "cd" with no arguments takes you to your home directory.
If it didn't, then a simple function in one's ~/.bashrc (etc) would do the job:
ho () {
cd $HOME
}
Now HERE'S a useful little function.
cs () {
cd "$1" && ls -Fa
}
A combination of cd and ls. Type cs and your destination directory, and you go there AND ls is -Fa is run on the directory.

We probably should have just laid back and waited for some newbie to install it....
Wouldn't it have been fun to guide them through the compilation steps? Help them create the Makefile?
:-)
(On the other hand, they'd learn a lot by doing it, so....?)
My second thought after laughing out loud was that it could be malicious code...

% pwd /usr/home/kkeller % cd /ive/been/wandering/far % home % pwd /ive/been/wandering/far
Works great! When's v2.0 coming out? I think you should rewrite it in assembly, so that it's more efficient.

No, that should be done in shell......

Here are my shorter GPL versions of your home command.
Version 1 :-
alias home=cd
Version 2 :-
alias home='cd $HOME'
most systems should work with version 1, all should work with version 2.

His is trying (and failing) to go to the home directory of the person who is logged into the controlling terminal of the process, which means if you login as foo, and then "su -", it should still take you to ~foo.
How about something like this function in bash?
home() { TTY=`tty | sed 's/\/dev\///'` WHOLINE=`who | grep $TTY | sed 's/ .*//'` eval cd ~$WHOLINE }

I miss the configure script, the Makefile and man file. An rpm would be nice too. Also this program doesn't follow the gnu presciptions of the --version and --help options.
An alternative is: alias home=cd
I'm glad you didn't patent your invention. I for me will keep typing cd because it saves two letters.

It would be even more amusing to submit it to the Patent Office.
They'd probably approve it, and then IBM would contest it and show that they already patented it years ago..
