hi guys, i really need some help asap. Im taking an OS class and we barely skimmed over Linux. We were asked a homework question that for the life of me i have no idea how to do. the qestion is... write a shell script that accepts a number from the user and displays the squares of all numbers from 1 up to that number as follows:
1 square=________ 2 square=________ : : n square=________ (n is the number entered)
PLease help if possible. its due tomorrow and i havent even begun to figure it out. Thanks! Todd

#!/bin/ksh if [ $# -gt 0 ] ; then i=1 square_cnt=$1 while [ $i -le $square_cnt ] ; do ((square = $i * $i )) echo "$i square = $square" ((i = i + 1)) done else echo "ERROR. Please enter an integer" fi
You should make a sanity check to make sure someone does not pass a non-integer on the command line. Hope you get a good grade. O'Reilly has a nice book on KSH. For future questions, the unix list here is more adept at scripting questions.
