This won't do what you think. $PWD and $1 are substituted when the
alias is defined, not when it is used. You can define the alias like
this to get what you want:
alias tryme='"$PWD/$1"'
This happens to work, but I'm not sure whether it's by design or by
accident. The right way is to use a function instead of an alias:
tryme() { "$PWD/$1"; }
