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 roland _______________________________________________ linux-lvm mailing list [email protected] https://listman.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
