bdfmegs has been upgraded to 4.8 and has added the following new features:
- overflow with terabyte filesystems and sum totals has been corrected
- select by volume group -V vgname
- sort by column number -c ##
To keep the number fields at a reasonable size, bdfmegs will display numbers more than 9999 with a suffix (g=giga, t=tera, p=peta). For very large filesystems, use -g or link bdfmegs to bdfgigs and bdfgigs will show numbers in gigabytes. Sum totals can now handle terabytes and petabytes.
You can now select one volume group by name as in:
$ bdfmegs -V vg00
File-System Mbytes Used Avail %Used Mounted on
/dev/vg00/lvol3 2504 399 2104 16% /
/dev/vg00/lvol1 291 93 169 36% /stand
/dev/vg00/lvol8 8192 3125 5048 39% /var
/dev/vg00/lvol7 9600 4044 5513 43% /usr
/dev/vg00/lvol4 4096 114 3981 3% /tmp
/dev/vg00/lvol6 8800 6298 2482 72% /opt
/dev/vg00/lvol5 5000 651 4076 14% /Home
and it will show just the mounted vg00 logical volumes.
You can sort by any column. To sort by available space (col 4):
$ bdfmegs -s -c 4 -V vg00

-- sum totals - 37.6g 14.4g 22.8g --- sum totals ---
The above shows a sum total (-s) and sorted by column 4 (Avail).
For very large filesystems, use -g:
$ bdfmegs -s -V vgvlf
File-System Mbytes Used Avail %Used Mounted on
/dev/vgvlf/vlfa 1668.4g 64 1655.3g 1% /nshare1

-- sum totals - 3336.8g 42.8g 3268.2g --- sum totals ---
$ bdfmegs -gs -V vgvlf

-- sum totals - 3336 43 3268 --- sum totals ---
To see the usage summary, use -? as an option:
Usage: bdfmegs [ -clgPpqstuVv ] file(s) or dir(s) ]
where:
-c # = Sort on column #
-g = show gigabytes, otherwise megabytes
-l = local (no NFS)
-p ## = highlight % -ge ##
-P ## = show only % -ge ##
-q = suppress header line and no char enhancements
-s = summarize total, used and available
-t
= specifc filesystem: (hfs vxfs nfs cdfs cifs autofs DevFS)
-u = usage (return code=0, Usage to stdout)
-v = verbose (type, version, largefiles)
(version info read permission for mountpoint)
-V = select a volume group
File(s) or dirpath(s) may be specified to limit
the output of bdfmegs as in:
bdfmegs -vlg /usr/contrib/bin /var/tmp
If bdfmegs is run as bdfgigs (ie, a link), then -g is default.
