Can someone please tell me which command to use to determine the available disk space on a given disk device?
I have to write a shell script that compresses files and stores them in a specific location but I am not sure how "conservative" I should be?
Thanks in advance!

snmpdf
SNMPDF(1) Net-SNMP SNMPDF(1) NAME
snmpdf - display disk space usage on a network entity via SNMP SYNOPSIS
snmpdf [COMMON OPTIONS] [-Cu] AGENT DESCRIPTION
snmpdf is simply a networked verison of the typical df command. It checks the disk space on the remote machine by examining the HOST- RESOURCES-MIB's hrStorageTable or the UCD-SNMP-MIB's dskTable. By default, the hrStorageTable is preferred as it typically contains more information. However, the -Cu argument can be passed to snmpdf to force the usage of the dskTable. AGENT identifies a target SNMP agent, which is instrumented to monitor the gievn objects. At its simplest, the AGENT specification will consist of a hostname or an IPv4 address. In this situation, the command will attempt communication with the agent, using UDP/IPv4 to port 161 of the given target host. See the snmpcmd(1) manual page for a full list of the possible formats for AGENT. See the snmpd.conf(5) manual page on setting up the dskTable using the disk directive in the snmpd.conf file. OPTIONS
COMMON OPTIONS Please see snmpcmd(1) for a list of possible values for COMMON OPTIONS as well as their descriptions. -Cu Forces the command to use dskTable in mib UCD-SNMP-MIB instead of the default to determine the storage information. Generally, the default use of hrStorageTable in mib HOST-RESOURCES-MIB is preferred because it typically contains more information. EXAMPLES
