hello,
does somebody know how we can have native (i.e. non translated) column
field names in first line of output of pvs ?
in its current implementation, output is hard to read , difficult to
distinguish and also not scriptable/parseable, as whitespace is used for
field separator and there are fields which also contain whitespace
themselves,and there also seems no way to add separators in between
(like with printf) for separation/formatting
# pvs --units s -o+pv_ba_start,seg_start,seg_start_pe,pvseg_start
PV VG Fmt Attr PSize PFree BA Start Start
Start Start
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S
2097152S 1 0
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S
2097152S 1 1
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S 0S 0 5309
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S 0S 0 5587
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S 0S 0 5588
i mean like this:
# pvs --units s -o+pv_ba_start,seg_start,seg_start_pe,pvseg_start
PV VG Fmt Attr PSize PFree pv_ba_start
seg_start seg_start_pe pvseg_start
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S
2097152S 1 0
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S
2097152S 1 1
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S 0S
0 5309
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S 0S
0 5587
/dev/sdb VGrecycle lvm2 a-- 11720982528S 0S 0S
0S 0 5588
furthermore, it's a little bit weird that some columns being printed by
default when using -o, is there an easier way to remove those besides
explictly removing them one by one with several -o options ?
"-o-opt1,-opt2,..." doesn't work
# pvs --units s -o+pv_ba_start,seg_start,pvseg_start,seg_start_pe
-o-vg_name -o-pv_name -o-pv_fmt -o-attr -o -pv_size -o -pv_free
BA Start Start Start Start
0S 2097152S 0 1
0S 2097152S 1 1
0S 0S 5309 0
0S 0S 5587 0
0S 0S 5588 0
