Re: [TCLUG:1502] odd bash script problem

[Nate Carlson <natecars@infiniteloop.com>]

Try changing the 'if [ $2 = "new" ]' to 'if [ "$2" = "new" ]' .. I don't
know much about bash, but you can run into problems with it thinking there
is nothing to the left of the = if you do not use quotes to specify
blank.. so if you enter nothing for $2, bash may be interpret the way you
have it like 'if [  = "new" ]' instead of 'if [ <blank> = "new" ]'.. give
it a try, I could be wrong tho.
