regular expressions
Hello,
Let say I have a string with content "Free 100%". How can extract only "100" using ksh? I would this machanism to work if instead of "100" there is any kind of combination of numbers(ex. "32", "1238", "1"). I want to get only the digits. I have written something like this: result="Free 100%" final=`expr "$result" : "Free *\(.*\)"` It returns "100%". I still can not elimanate the "%". Please help :-) Thank you! |
