How to exclude multiple types of File System in df output using -x flag


Actual #

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg00-rootvol
25G 6.8G 17G 30% /
/dev/mapper/vg00-tmpvol
4.7G 594M 3.9G 14% /tmp
/dev/mapper/vg00-varvol
9.4G 907M 8.0G 10% /var
/dev/mapper/vg00-auditvol
120M 98M 17M 86% /var/log/audit
/dev/mapper/vg00-crashvol
45G 77M 43G 1% /var/crash
/dev/mapper/vg00-homevol
4.7G 44M 4.4G 1% /home
/dev/mapper/vg02-RhelRepo
9.9G 7.7G 1.7G 83% /var/repo
/dev/cciss/c0d0p1 251M 23M 216M 10% /boot
tmpfs 24G 460M 23G 2% /dev/shm
/dev/mapper/vg01-swap
46G 46G 0 100% /root/swapfile



Required #

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg00-rootvol
25G 6.8G 17G 30% /
/dev/mapper/vg00-tmpvol
4.7G 594M 3.9G 14% /tmp
/dev/mapper/vg00-varvol
9.4G 907M 8.0G 10% /var
/dev/mapper/vg00-auditvol

9.9G 7.7G 1.7G 83% /var/repo
/dev/cciss/c0d0p1 251M 23M 216M 10% /boot

Command used #
df -hx tmpfs -x swap -x iso9660

why?
to exclude swap and iso9660 filesystem type.

what is required now?
Option1:
Is there a way wherein we give both the file system type with only one "-x" in the above given command?
Option2:
How to declare this as a variable in the beginning of the script? e.g. TYPE=iso9660,swap,tmpfs,etc.

Is this your homework? I would say you need to write a small wrapper script to implement that.

Yes, it is a homework, but for my official work.

Could you brief me bit more on the wrapper scripts?

so the wrapper script should accept the argument you specified (a comma separated list) and reformat it using the original syntax. Would be nice if you could show us what have you made already - just to be able to continue ....
