The filesystems Command

The filesystems Command

By default, list and step commands display all writable filesystems that are local to the target; disk space estimates reflect an aggregate of the software that is selected to be installed on all locally mounted filesystems. Using the filesystems command, you can change list and step output to report space requirements on individual filesystems, on read-only filesystems, and on NFS filesystems that are writable.

Most arguments to the filesystems command are paired:

on, off: toggles space estimates to individual or aggregate filesystems
local, nfs: specifies whether space estimates reflect locally mounted filesystems (the default) or writable NFS filesystems
readonly, all: specifies whether space estimates reflect just read-only filesystems or writable and read-only filesystems
filesystem_name: Any filesystem specification

Any filesystems command entry overrides the previous filesystems entry.

Example 5-6 illustrates how to display individual filesystems in a list display. Notice that the sort command from Example 5-5 is still in effect, so images are sorted by size on the root filesystem (/) first, then on /disk_2, and finally on /disk_3.

Example 5-6 : Displaying Individual Filesystems Example 5-7 shows how you can change the columns that are shown in list and step displays. Notice that /disk_2 software appears before / software, as specified by the order of filesystems command arguments, and the /disk_3 filesystem does not appear in the listing, since it is not specified as an argument. The filesystems command is abbreviated in this example.

View> fs /disk2 /
View> return list
                                 /disk2         /
