linux - Convert string to hexadecimal on command line -

-

i'm trying convert "hello" 48 65 6c 6c 6f in hexadecimal efficiently possible using command line.

i've tried looking @ printf , google, can't anywhere.

any appreciated.

many in advance,

echo -n "hello" | od -a n -t x1

explanation:

  • the echo program provide string next command.
  • the -n flag tells echo not generate new line @ end of "hello".
  • the od program "octal dump" program. (we provide flag tell dump in hexadecimal instead of octal.)
  • the -a n flag short --address-radix=n, n being short "none". without part, command output ugly numerical address prefix on left side. useful large dumps, short string unnecessary.
  • the -t x1 flag short --format=x1, x being short "hexidecimal" , 1 meaning 1 byte.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
