substring a date

Hi all, I have used a bash script which ultimately converts a string into date using date --date option:

Code:

DATE=$DATE" "$TIME" "`date +%Y` //concatenating 2 strings TMRW_DATE=`date --date="$DATE" +"%s"` //applying date command on string and getting the unixtime

Please use next time code

Dear All,

I am new here.

I am trying to calculate the maximum number from four numbers input by the user. I have the following code, but it does not work. It says there's an error with the last line "done". Any help would be appreciated.

Code: sort -t "~" -k 1.19,1.29 -k 2.1,2.5 in unix

- I have to understand what exactly this command will do ?:wall:

Hi,

I am getting this error while running the following code.

Code: i=`awk '{print $2}' test1.txt` j=`awk '{print $4}' test1.txt` k=`awk '{print $6}' test1.txt` if [ $i =="Yes" && $j =="Yes" && $k =0 ]; then echo "Up." else echo "down" fi rm -f test.txt test1.txt error is this:

Code: line 12: [: missing `]' Please suggest.

i created a code that calculates informational entropy i.e lots of large sums times logs base 2. At fifth level entropy however, my code just stops and yields math range error. I was playing around with a frequency function I'm using, and I think I might have an int/float error. Has anyone run into this? Has anyone found a way around this?
