not knowing how many lines of input have no reason use array. indeed, more useful if assume input infinite (an input stream), reading array impossible. read each line , take action if necessary:

#!/bin/sh while read -r count user;   if test "$count" -gt 50;        echo "$user has sent $count emails"   fi    done < /root/.myscripts/spam1/info.txt
