How to remove the first character on a string in a variable
Hi all,

Does anyone know how to code in ksh that will remove the first character in a string variable and replace that variable without the first character?

Example:

var1=ktest1 will become var1=test1
var2=rtest2 will become var2=test2

Need help please.
