Full Discussion: Using wildcards in "if" statement

It should work with shells that support the double brackets though:

Code:
$ Author=b ; if [[ $Author = [a-z] ]]; then echo hello; fi
hello

If you are looking to see if the input consists only of lower case standard characters:
Code:
if ! [[ $Author = *[^a-z]* ]]; then 
  echo hello
fi

For Posix compliancy you would need to use the case statement though:
Code:
case $Author in 
  *[^a-z]*) echo wrong ;;
         *) echo right ;; 
esac

To test whether anything is input:

Code:
if [ -n "$Author" ]; then
  echo not empty
fi
