--and this can be a little more complicated than first appears if you have
to worry about several such attempts. the whole series will have to be
sequenced, adding 1 on, and not forgetting that you have to turn any string
version of a number into an integer before you can add 1 on, then back to a
string again to rename. A good way to test for the existence of a the same
name already, that doesn't involve the Finder which can get quite gummed up
in these existence checks, is to do
try
get alias "Disk:Folder:1.eps"
-- doesn't error, means the thing exists, change name
set done to false
set j to 1
repeat until done
set jj to text -2 thru -1 of ("0" & j)
try
set theName to "Disk:Folder:1_" & jj & ".eps"
get alias theName
-- doesn't error, means it exists, change name
set j to j +1
on error -- doesn't exist
set done to true
end try
end repeat
on error -- 1.eps doesn't exist yet
set theName to "1.eps"
end try
tell application "Finder"
set name of theFile to theName
move theFile to someFolder
end tell
--------------
Make sure that theFile is predefined so that even if it takes the Finder its
customary 3 seconds or more to do the renaming, it can still find theFile to
move it. Don't refer to theFile by its new name when you move it, or it will
usually error. Even so, you may have Finder problems. If so, use Jon's
Commands or Akua Sweets to do the naming and moving, which I would
recommend.
