As you can see I have tons of space on "/space" I would like to allocate some of that space to /. Well, I'm not really a unix person, so I don't know what I am doing and I'm not sure that I want to risk messing up my system and it not booting up again. Maybe I'll just try to uninstall the apps I have on / and re-install them on /space

df
df(1B) SunOS/BSD Compatibility Package Commands df(1B)
NAME
df - display status of disk space on file systems
SYNOPSIS
/usr/ucb/df [-a] [-i] [-t type] [filesystem...]
[filename...]
DESCRIPTION
The df utility displays the amount of disk space occupied by currently mounted file systems, the amount of used and available space, and
how much of the file system's total capacity has been used.
If arguments to df are path names, df produces a report on the file system containing the named file. Thus `df .' shows the amount of
space on the file system containing the current directory.
OPTIONS
The following options are supported:
-a Report on all filesystems including the uninteresting ones which have zero total blocks (that is, auto-mounter).
-i Report the number of used and free inodes. Print ` * ' if no information is available.
-t type Report on filesystems of a given type (for example, nfs or ufs).
EXAMPLES
Example 1 Using df
A sample of output for df looks like:
example% df
Filesystem kbytes used avail capacity Mounted on
sparky:/ 7445 4714 1986 70% /
sparky:/usr 42277 35291 2758 93% /usr
Note that used+avail is less than the amount of space in the file system (kbytes); this is because the system reserves a fraction of the
space in the file system to allow its file system allocation routines to work well. The amount reserved is typically about 10%; this can be
adjusted using tunefs (see tunefs(1M)). When all the space on a file system except for this reserve is in use, only the super-user can
allocate new files and data blocks to existing files. When a file system is overallocated in this way, df can report that the file system
is more than 100% utilized.
FILES
/etc/mnttab List of file systems currently mounted
/etc/vfstab List of default parameters for each file system
