The normal approach is to use "df" and parse the results. Giving a path will just return you stats on that path, and the "-k" option gives you results in kilobytes rather than 512byte sectors.
eg "df -k $HOME" or "df -k ." etc.

fs_listquota
FS_LISTQUOTA(1) AFS Command Reference FS_LISTQUOTA(1)
NAME
fs_listquota - Displays quota information for a volume
SYNOPSIS
fs listquota [-path <dir/file path>+] [-human] [-help]
fs listq [-p <dir/file path>+] [-hu] [-he]
fs lq [-p <dir/file path>+] [-hu] [-he]
DESCRIPTION
The fs listquota command displays information about the volume containing each specified directory or file (its name, quota, and amount of
disk space used), along with an indicator of the percentage of space used on the host partition.
To display more information about the host partition, use the fs examine command.
To set volume quota, use the fs setquota or fs setvol command.
CAUTIONS
Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).
OPTIONS
-path <dir/file path>+
Names a file or directory that resides in the volume about which to produce output. Partial pathnames are interpreted relative to the
current working directory, which is also the default value if this argument is omitted.
-human
Print space in a "human-readable" format. Instead of always printing space in kilobytes, show disk space in kilobytes, megabytes,
gigabytes, terabytes, or petabytes, as appropriate.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output displays information about the volume that houses each specified directory or file, in a tabular format that uses the following
headers:
Volume Name
The name of the volume.
Quota
The volume's quota in kilobytes, or the string "no limit" to indicate an unlimited quota.
Used
The amount of space used. If -human is not specified, this value is in kilobytes.
% Used
The percentage of the volume's quota that is used (the "Used" statistic divided by the "Quota" statistic, times 100).
Partition
The percentage of space used on the partition that houses the volume. Although not directly related to how much of the user's quota is
used, it is reported because a full partition can cause writing of data back to the volume to fail even when the volume has not reached
its quota.
EXAMPLES
The following example shows the output for the volume "user.smith":
% fs listquota -path /afs/abc.com/usr/smith
Volume Name Quota Used % Used Partition
user.smith 15000 5071 34% 86%
PRIVILEGE REQUIRED
The issuer must have the "r" (read) permission on the ACL of the root directory of the volume that houses the file or directory named by
the -path argument, and "l" (list) permission on the ACL of each directory that precedes it in the pathname.
