How does string interpolation work in bash? -


i trying interpolate parameter's value in string. let me present simple example generality , simplicity.

size="40" #yes, variable size string echo "total bytes $size" #^ works fine: outputs total bytes: 40 echo "total bytes: $size bytes" #outputs  bytesbytes: 40 #the string " bytes" inserted @ beginning overwriting other string- why?

i have tried multiple variations of these commands none seem work leading me believe making classic noob mistake. suggestions welcome.

you have saved file crlf line endings.

try dos2unix your_script_file if distro has it.
else solution: sed -i $'s/\r//' your_script_file

i guess script obtained curl, dangerous practice. however, not go details now.

you can pipe curl output through tr -d '\r' getting correct script want.

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)...
