T-Shirt
« on: February 14, 2013, 07:47:48 AM »
I saw the following in Google+:

"There's no place like ~/."

Maybe it'd be a it clearer/funnier to have, "There's no place like /home."

It'd make a great T-Shirt.:)

Well, I thought they both mean the same thing.  Am I wrong?

Yes, they do but ~/ is even more teasing... and more geeky :)

I have also seen "There is no place like 127.0.0.1" :P

I would say that /home/ is incorrect...

I saw a doormat with "There's no place like 127.0.0.1" I don't think I like it... 127.0.0.1 is not 'home' it's 'localhost'... I can get 127.0.0.1 if I connect to the network anywhere... and it does not means that I am home... "There's no place like ~", "There's no place like ~/" or "There's no place like $HOME" would be cooler...

Also... There is no 127.0.0.1 folder...

[andrzejl@wishmacer ~]$ cd 127.0.0.1
bash: cd: 127.0.0.1: No such file or directory

So You cannot go home this way ;D!

@ Mark /home/ is where everyone's home could be. /home/mark/ is where Your home is. Treat /home/ as the neighborhood :) cd ~ or cd ~/ or cd $HOME will take You home... cd /home/ however - will not :). You should not have write access rights to the /home/ folder :) unless You're root... but then root's home is in /root/ folder. Treat root as a landlord - he can get You Your ~ folder or he can have You evicted ;)...

Well, I thought they both mean the same thing.  Am I wrong?

They are different

~/  .......  /home/<user-name>/

/home/ .......  is not the same .....

try in a terminal

cd  ~/

and

cd /home/

and see the difference in the prompts or the output from the   ls  command  ;)

Just curious, why is the "/" necessary in "~/", or is it?

Its not, in my example, but as all others had a trailing slash then that got it too.

so

cd  ~

is equally valid.

You could go to a specific directory in your home by specifying a "/directory" after the "~".

e.g. "cd ~/photos"  ;)

This command would take you to "/home/yourusername/photos"  if it existed.

Anytime you add a trailing "/" but do not specify a directory or file name, it is pretty much ignored.  

*Just adding to the info*  ;)

The trailing / means the contents of a directory. Without that it means the file that contains the directory, which is usually the same thing, but not always. If the file is a symbolic link, for instance, "ls file" will just list "file@", whereas "ls file/" will list the contents of the linked directory.

On application forms they often have three boxes for phone numbers: work,home and mobile. I really prefer not to give out a home number so I write 127 001.

Noone ever looks twice.
