unix - How to use cut and paste together in one go -


i trying use cut , paste in same command line somehow not work. have 2 files, filea , fileb. 

filea b c d   fileb 1 2 3 4 5 6 7 8

i cut second , third column of fileb. following command.

cut -f 2-3 fileb

then in front of this, paste columns filea

paste filea | cut -f 2-3 fileb > mynewfile

so mynewfile like

a b 2 3 c d 6 7

i can in 2 lines. 

cut -f 2-3 fileb > part1 paste filea part1 > mynewfile

but instead, in 1 go. similar to

paste filea | cut -f 2-3 fileb > mynewfile

which not work. prints cut commands , not paste. how can make work in 1 command?

thanks.

solution 1:

paste filea <(cut -f 2-3 fileb) > mynewfile

solution 2:

paste filea fileb | cut -f1-2,4-5

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
