Need help in manipulating string variable
I have written a shell script to do some processing and have to manipulate a variable. Basically, the variable is like this --
var=set policy:set cli

My purpose is to split it into two variables based on the position of ":". To get the right end, I am doing this --

vaa1=${vaa#*:}
echo ${vaa1} //this prints "set cli" which I want
However, I am not able to get the left part of the string "set policy". I tried doing this --
vaa2=${vaa%*:}

But it didn't work and I am getting the whole string--"set policy:set cli". Any ideas on how to get the left part ?
