AVAIL AmigaDOS
Purpose: To report the amount of memory available on the system.
Format: AVAIL [CHIP | FAST | VIRTUAL | TOTAL] [FLUSH] [SHOW <show>]
Template: CHIP/S, FAST/S, TOTAL/S, FLUSH/S, VIRTUAL/S, SHOW/K
Path: C:AVAIL
AVAIL gives a summary of the system RAM, analysed by Chip RAM, Fast RAM and Virtual memory. For each memory type, AVAIL reports the total amount of memory, how much is available, how much is currently in use, and the largest contiguous block not yet allocated.

By using the CHIP, FAST, VIRTUAL, and/or TOTAL options, you can have AVAIL display only the number of free bytes of CHIP, FAST, VIRTUAL or TOTAL RAM available, instead of the complete summary. This value can be used for comparison in scripts.

The FLUSH option causes all unused libraries, devices, and fonts to be expunged from memory.

The SHOW <show> argument can be used to specify the displayed format. The options are:

    BYTE - display memory in bytes (default)
    KILO - display memory in kilobytes
    MEGA - display memory in megabytes

Example 1:

3.OS4:> AVAIL
Installed: 536,870,912
Free:      483,663,872 A complete summary of system RAM is displayed in bytes.

Example 2:

3.OS4:> AVAIL SHOW MEGA
Installed: 512.000 M
Free:      461.237 M A complete summary of system RAM is displayed in megabytes.

Example 3:

3.OS4:> AVAIL CHIP
2067904 The number of free bytes of CHIP RAM is displayed.
