I want to compare values of two variables as CHECK condition in a while loop.


while [ $var1 < $var2 ] 
    echo " $var1 "
    var1=`expr $var1 + 1`

However this is giving error.How to do it in a proper manner?

while [ $var1 -lt $var2 ]

"<" is used for redirection

gawk -v v1="$var1" -v v2="$var2" 'BEGIN{
    while(v1 < v2){
        print v1
} '
