I'm looking for the place where $HOME environment variable set. It is after login, to my mind.

I'm using Linux debian 2.6.32-5-686.

If you are attempting to modify your HOME, you can do

export HOME=/home/... 

either in your shell, or in your ~/.profile file and/or ~/.bashrc (or appropriate login shell).

(The above code will work for bash and similar shells, which are default in Debian; you would otherwise do `setenv HOME $HOME:/extra/path I think on csh-like shells in other distros.)

edit -- However this is probably not the way to do it. See other answers. Do not use this answer.

You are likely confusing $HOME with $PATH. It does not make sense to have multiple paths in $HOME (the entire value will be treated as a single pathname) or, in most cases, to modify $HOME at all. –  grawity Sep 9 '12 at 20:55

On Linux, the HOME environment variable is set by the login program:

  • by login on console, telnet and rlogin sessions
  • by sshd for SSH connections
  • by gdm, kdm or xdm for graphical sessions.

The login program arranges it before calling exec on your shell (by including it in the arguments to exec), based on the value in /etc/passwd.

Edit this by running: usermod -d /home/whatever_dir whatever_user.

Please note that this will (obviously) be the new home directory. Bash will cd to it on login, so make sure it exists and the permissions are correct. In addition, don't forget about .bashrc, .profile, .xinitrc, etc; if they're not in the home directory, they will not be read.

From usermod:

Usage: usermod [options] LOGIN

Options:
  -c, --comment COMMENT         new value of the GECOS field
  -d, --home HOME_DIR           new home directory for the user account
  -e, --expiredate EXPIRE_DATE  set account expiration date to EXPIRE_DATE
  -f, --inactive INACTIVE       set password inactive after expiration
                                to INACTIVE
  -g, --gid GROUP               force use GROUP as new primary group
  -G, --groups GROUPS           new list of supplementary GROUPS
  -a, --append                  append the user to the supplemental GROUPS
                                mentioned by the -G option without removing
                                him/her from other groups
  -h, --help                    display this help message and exit
  -l, --login NEW_LOGIN         new value of the login name
  -L, --lock                    lock the user account
  -m, --move-home               move contents of the home directory to the
                                new location (use only with -d)
  -o, --non-unique              allow using duplicate (non-unique) UID
  -p, --password PASSWORD       use encrypted password for the new password

  -s, --shell SHELL             new login shell for the user account
