#1299 PR merged: exclude tmpfs from df.txt and replace grep¶

Labels: enhancement, fixed / solved / done

ProBackup-nl opened issue at 2017-04-14 15:04:¶

Gnu df at least since 2013 contains the -x option to "Exclude Certain File System Type":
-x, --exclude-type=TYPE limit listing to file systems not of type TYPE
There is no need to use grep to exclude file systems.

Also including tmpfs and devtmpsfs clutters the output. Exclude these file systems too.

Output before change:

Filesystem      Size  Used Avail Use% Mounted on
dev             3.9G     0  3.9G   0% /dev
run             3.9G  696K  3.9G   1% /run
/dev/sda2        20G  2.1G   18G  11% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
tmpfs           3.9G     0  3.9G   0% /tmp
/dev/sda3       9.3G   17M  9.3G   1% /home
/dev/sda1      1022M   44M  979M   5% /boot
tmpfs           789M     0  789M   0% /run/user/0

Output after change:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2        20G  2.1G   18G  11% /
/dev/sda3       9.3G   17M  9.3G   1% /home
/dev/sda1      1022M   44M  979M   5% /boot

That makes the output readable.

FIXME: Non GNU df versions might lack support for option -x.
