Alternative commands
To make the command vi run vim, use update-alternatives:
# update-alternatives --display vi ... # update-alternatives --config vi Selection Command ----------------------------------------------- 1 /usr/bin/elvis-tiny 2 /usr/bin/vim *+ 3 /usr/bin/nvi
Enter to keep the default[*], or type selection number: 2
Items in the Debian alternatives system are kept in /etc/alternatives as symlinks.
To set your favorite X Window environment, apply update-alternatives to /usr/bin/x-session-manager and /usr/bin/x-window-manager. For details, see Custom X sessions, раздел 9.4.5.1.
/bin/sh is a direct symlink to /bin/bash or /bin/dash. It's safer to use /bin/bash to be compatible with old Bashism-contaminated scripts but better discipline to use /bin/dash to enforce POSIX compliance. Upgrading to a 2.4 Linux kernel tends to set this to /bin/dash.
