bdf , /etc/fstab , /etc/mnttab
Hi all, Would like to know if it is possible to rearrange the order that mounts are displayed when the 'bdf' command is issued. An example of what I mean is, currently I see the following ... Code:
[mddev:/home/cameron] $ bdf -l Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 524288 211800 310104 41% / /dev/vg00/lvol1 1048576 792464 254216 76% /stand /dev/vg00/lvol7 4194304 2111048 2066992 51% /var /dev/vg00/lvol6 5275648 4324952 943312 82% /usr /dev/vg00/lvolu3 30736384 3901997 25157825 13% /u03 /dev/vg00/lvolu2 27033600 21665312 5034033 81% /u02 /dev/vg00/lvolu1 20480000 16962500 3298935 84% /u01 /dev/vg00/lvol5 229376 103248 125280 45% /tmp /dev/vg00/lvol4 4620288 3775088 838648 82% /opt /dev/vg00/lvol8 1048576 141744 899856 14% /home /dev/vg00/lvolu4 5144576 2148221 2809135 43% /u04 But would prefer to see the mounts in the following order ... Code:
Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 524288 211800 310104 41% / /dev/vg00/lvol6 5275648 4324952 943312 82% /usr /dev/vg00/lvol7 4194304 2111048 2066992 51% /var /dev/vg00/lvol4 4620288 3775088 838648 82% /opt /dev/vg00/lvol8 1048576 141744 899856 14% /home /dev/vg00/lvol1 1048576 792464 254216 76% /stand /dev/vg00/lvol5 229376 103248 125280 45% /tmp /dev/vg00/lvolu1 20480000 16962500 3298935 84% /u01 /dev/vg00/lvolu2 27033600 21665312 5034033 81% /u02 /dev/vg00/lvolu3 30736384 3901997 25157825 13% /u03 /dev/vg00/lvolu4 5144576 2148221 2809135 43% /u04 I had a play about and altered the order of items in the /etc/fstab with no change to the output order and have read that changing /etc/mnttab is not recommended or of any use. Whilst the example is for the local mounts, if a solution is possible then I'd also apply the same for NFS mounts too. A strange query I'd admit, but curious to know if it is possible.

Thanks Perderabo.
Any chance of a lead for understanding/creating a wrapper (never looked before). Searching the forums, there are (of what I've searched so far) only references to wrappers. Cheers, Cameron |

A wrapper is just a script that you call instead of the actual command (bdf) in your case. The script will modify your output as you wish, by internally calling stuff like sort/awk/whatever. Once you get the script in place, do not run bdf directly, but the always the script instead.

It occurred to me that a non-general solution is very easy. All you need is a control file with line numbers. You paste the control file on to the output from bdf, sort, then cut away the line numbers. I am not on an HP-UX system, so to demo this, first I need an ersatz bdf command. Code:
$ export PATH=$PATH:. $ cat bdf #! /usr/bin/sed 1d Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 524288 211800 310104 41% / /dev/vg00/lvol1 1048576 792464 254216 76% /stand /dev/vg00/lvol7 4194304 2111048 2066992 51% /var /dev/vg00/lvol6 5275648 4324952 943312 82% /usr /dev/vg00/lvolu3 30736384 3901997 25157825 13% /u03 /dev/vg00/lvolu2 27033600 21665312 5034033 81% /u02 /dev/vg00/lvolu1 20480000 16962500 3298935 84% /u01 /dev/vg00/lvol5 229376 103248 125280 45% /tmp /dev/vg00/lvol4 4620288 3775088 838648 82% /opt /dev/vg00/lvol8 1048576 141744 899856 14% /home /dev/vg00/lvolu4 5144576 2148221 2809135 43% /u04 $ $ $ $ cat control 01 02 03 04 05 11 10 09 06 07 08 12 $ $ $ $ bdf Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 524288 211800 310104 41% / /dev/vg00/lvol1 1048576 792464 254216 76% /stand /dev/vg00/lvol7 4194304 2111048 2066992 51% /var /dev/vg00/lvol6 5275648 4324952 943312 82% /usr /dev/vg00/lvolu3 30736384 3901997 25157825 13% /u03 /dev/vg00/lvolu2 27033600 21665312 5034033 81% /u02 /dev/vg00/lvolu1 20480000 16962500 3298935 84% /u01 /dev/vg00/lvol5 229376 103248 125280 45% /tmp /dev/vg00/lvol4 4620288 3775088 838648 82% /opt /dev/vg00/lvol8 1048576 141744 899856 14% /home /dev/vg00/lvolu4 5144576 2148221 2809135 43% /u04 $ $ $ $ bdf | paste control - | sort -n | cut -f2 Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 524288 211800 310104 41% / /dev/vg00/lvol1 1048576 792464 254216 76% /stand /dev/vg00/lvol7 4194304 2111048 2066992 51% /var /dev/vg00/lvol6 5275648 4324952 943312 82% /usr /dev/vg00/lvol5 229376 103248 125280 45% /tmp /dev/vg00/lvol4 4620288 3775088 838648 82% /opt /dev/vg00/lvol8 1048576 141744 899856 14% /home /dev/vg00/lvolu1 20480000 16962500 3298935 84% /u01 /dev/vg00/lvolu2 27033600 21665312 5034033 81% /u02 /dev/vg00/lvolu3 30736384 3901997 25157825 13% /u03 /dev/vg00/lvolu4 5144576 2148221 2809135 43% /u04 $ |
