The first column is the closing price of a stock (close_price), the second column contains the fast exponential moving average (fast_ema) and the third column contains the slow exponential

问题 I'm having a syntax error with this if block and can't I haven't been able to correct it if [[ $X >= 100] || [$Y >= 100 ]] then echo "..." fi I've rewrote this, but haven't had any luck on finding the correct syntax. Thanks in advance! 回答1: This is a syntax error, you should try : if ((X >= 100 || Y >= 100 )) then echo "..." fi NOTE with this syntax, no need to remember -ge and such. This is just like arithmetic ((...)) is an arithmetic command, which returns an exit status of 0 if the

问题 I am trying to get something of the effect that when I have an if statement: if({TRUE;FALSE;TRUE},{1,2,3}) it will return with {1,3} is there any way to get this effect with an array of conditions and return an array of results? 回答1: If one has the Dynamic Array Formula FILTER: =FILTER({1,2,3},TRANSPOSE({TRUE;FALSE;TRUE})) Without dynamic Array formula: =TRANSPOSE(MODE.MULT(IF({TRUE;FALSE;TRUE},ROW(1:3)*{1,1}))) This is an array formula and depending on ones version, it may need to be
