the new shell user marcy will be using. For example:
Old shell: /bin/sh

9.3.4 Setting File System Quotas
If you configured your system with file system quotas (also called disk
quotas), you can set a quota for the number of inodes or disk blocks allowed
for each user account or group on your system. To optimize disk space and
to save yourself some work, set quotas by grouping user accounts according
to their need for disk space. The following information is specific to the
UNIX File System (UFS). If you are using the Advanced File System
(AdvFS), refer to the
AdvFS Administrationguide.
9.3.4.1 Understanding User Account and Group Quota Limits
You set quotas for user accounts and groups by file system. For example, a
user account can be a member of several groups on a file system and also a
member of other groups on other file systems. The file system quota for a
user account is for a user account’s files on that file system. A user
account’s quota is exceeded when the number of blocks (or inodes) used on
that file system are exceeded.
Like user account quotas, a group’s quota is exceeded when the number of
blocks (or inodes) used on a particular file system is exceeded. However, the
group blocks or inodes used only count toward a group’s quota when the
files that are produced are assigned the GID for the group. Files that are
written by the members of the group that are not assigned the GID of the
group do not count toward the group quota.
_______________________ Note _______________________
Quota commands display block sizes of 1024-byte blocks.
A hard limit is one more unit (blocks, files, inodes) than will be allowed
when the quota limit is active. The quota is up to, but not including the
limit. For example, if you set a hard limit of 10,000 disk blocks for each
user account in a file system, an account reaches the hard limit when 9,999
disk blocks have been allocated. If you want a maximum of 10,000 complete
blocks for the user account, you must set the hard limit to 10,001.
