bash - Split column and use first array to headerin awk -


i have file looks this:

a=10 b=8 c=12 a=15 b=12 c=5 a=6 b=4 c=9 a=8 b=8 c=9

columns more. split file using awk , use letter before "=" header:

a b c 10 8 12 15 12 5 6 4 9 8 8 9

i like:

awk '{split($0,arr0,"="); print arr0[2]}' infile

but still not know how use arr0[1] header.

thank ideas.

using awk can this:

awk -f '[= ]' 'function prnt(start) {    (i=start; i<=nf; i+=2)       printf "%s%s", (i==start?"":ofs), $i    print "" } nr==1 {    prnt(1) } {    prnt(2) }' file  b c 10 8 12 15 12 5 6 4 9 8 8 9

and tabular formatted output use:

awk -f '[= ]' 'function prnt(start) {    (i=start; i<=nf; i+=2)       printf "%s%s", (i==start?"":ofs), $i    print "" } nr==1 {    prnt(1) } {    prnt(2) }' file | column -t    b   c 10  8   12 15  12  5 6   4   9 8   8   9

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
