bdfmegs ver 6.2 now available

[Bill Hassell]

bdf is not very useable for GB and TB filesystems, and splits lines for long source device names.

bdfmegs is a script to provide one liners for every mountpoint, and summarize and provide detailed information about filesystems, as well as select filesystems based on VG/DG name, mountpoint name and percentage full.

Several new features have been added in the last year or so:

• Snapshot volumes are shown
• Added LVM VG version to -v option (11.31 feature)
• Added NFS version to -v option
• Added MemFS support
• Added VxVM paths to -N and -V options

Usage information:

# bdfmegs -?

Usage:  bdfmegs [ -cghlNPpqstuVv ] [ <file(s) or dir(s)> ]
  where:
    -c # = Sort on column #
    -d = Toggle divisor (1000 or 1024, current=1000)
    -e = enhancement for percentage and errors
         d=dim h=halfbright i=inverse u=underline b=blink
    -g = show gigabytes, otherwise megabytes
    -h = Usage
    -l = local (no NFS)
    -M   <mountpoints> = skip (grep -v) mountpoints
    -N   <VGnames> = skip one or more volume groups
         Repeat -N or use commas: -N vg10,vg24
    -p   ## = highlight % -ge ##
    -P   ## = show only % -ge ##
    -q = suppress header line and no char enhancements
    -s = summarize total, used and available
    -t   <fs> = filesystem: (hfs vxfs nfs cdfs cifs autofs DevFS memfs)
    -u = usage
    -v = verbose (FStype, FSversion, largefiles)
         (VG version needs read permission for devicefile)
    -V   <VGname> = select one or more volume groups
         Repeat -V or use commas: -V vg00,vg01

File(s) or dirpath(s) may be specified to reduce the output of bdfmegs:

       bdfmegs -vg /usr/contrib/bin . .. /var/tmp

If bdfmegs is run as bdfgigs (ie, a link), then -g is default.
                                         (bdfmegs ver 6.1_Nov2011)

Thanks, Bill.

hello,

this is a great tool !

i know, this is the wrong Community , but is there an initiative to port it to LINUX ?

i ported some tools from HPUX to LINUX and there are some changes, but no so big ones.

congratulation to the maintainer !

regards

[support_billa]

hello,

Ver 5.3 - Added -d to toggle ONEK between 1024 and 1000 for divisors
          The default can be changed by editing ONEK

In HP-UX 11.31 has "bdf" and "df -k" the same output, so i think is better to handle with unix release ( like uname -r ) the division ( HP-UX 11.31 division with 1024 ??? )

divison with 1000 is a little bit dizzying because bdfmegs differs from bdf

more details you can see in my attachment

regards

[Bill Hassell]

Correct. bdfmegs defaulted to 1000 because it looked a bit more accurate (at least for the first few digits). But you are correct. The more accurate divisor is 1024, so with the newest version (attached), the default is now 1024. Additionally, I have set a default sort order as the first column. bdf by itself has an unpredictable order so grouping all the VGs and lvols together makes a better presentation.

[support_billa]

hello,

thx for the new version:

i changed following part because i used it very often as "non root-user"

# filesystem types allowed
  set -A FSID $(/usr/sbin/fstyp -l)

regards

[Bill Hassell]

You're correct. /usr/sbin isn't always part of an ordinary user's $PATH

Thanks for the pointer. The fixed version is attached

[Bill Hassell]

Minor revision...the PATH list is actually set inside the script but was placed below the fstyp command. It has been moved back to the beginning of the script. Now bdfmegs runs without regard to the current PATH setting.

[Eshwar123]

Hi

Please help me

I am getting below errors while i am running the script.

I am a newbie to unix

dcdev01:root:/home/dcl2ux>./bdfmegs.sh

[Dennis Handly]

>dcdev01:root:/home/dcl2ux>./bdfmegs.sh

Does /usr/bin/sh exist and is it read and executable by all?  And the same with:

ll -d /usr/bin/sh /usr/bin /usr /
