Applescript to check for the existence of a file

applescript

I record radio programs during the night and then run an applescript to rename the files. I have the script working unless there is no file named that I am attempting to call and rename. Here is my code that is working:

set Yesterday to (current date) - (24 * 60 * 60)
set myYesterday to (date string of Yesterday)
set y to year of date myYesterday
set m to month of date myYesterday
set d to day of date myYesterday

set newMyYesterday to m & " " & d & ", " & y as text

set newHourOne to "Recording1 - " & newMyYesterday & " - Hour 1.mp3"
set theFile to (POSIX file "/Users/Administrator/Recordings/Recording1.mp3") as alias

tell application "Finder"
    set the name of file theFile to newHourOne
end tell

set newHourTwo to "Recording2 - " & newMyYesterday & " - Hour 2.mp3"
set theFile to (POSIX file "/Users/Administrator/Recordings/Recording2.mp3") as alias

tell application "Finder"
    set the name of file theFile to newHourTwo
end tell

Can someone please show me how to check to see if the individual file ("Recording1.mp3" or "Recording2.mp3") exist before trying to rename the individual file? Thanks!!

This should work:

if exists file theFile then
    # do stuff
else
    display dialog "File not found" buttons {"OK"} default button 1
end if

Why is the applescript for checking if a file exists failing

It looks like the Finder needs the absolute path to the home folder instead of the relative path. Instead of starting the path with ~/, it needs to start with /Users/username/.

Instead of hardcoding the username into the script, you can have AppleScript build the absolute path on the fly:

set homePath to POSIX path of (path to home folder)

Then you can replace "~/ with homePath & "

For example:

if exists "~/Downloads/Conversion/" & cbUsername & ".flv" as POSIX file then

would become

if exists homePath & "Downloads/Conversion/" & cbUsername & ".flv" as POSIX file then

Alternatively, if you only use ~ with the path ~/Downloads/Conversion/, you could instead change that whole path to a variable:

set cbPath to POSIX path of (path to home folder) & "Downloads/Conversion/"

Then the final script would be:

set cbPath to POSIX path of (path to home folder) & "Downloads/Conversion/"

tell application "Finder"
    if exists cbPath & cbUsername & ".flv" as POSIX file then
        set x to 1
        repeat
            set newCbFilename to cbUsername & "_" & x as string
            if exists cbPath & newCbFilename & ".flv" as POSIX file then
                set x to x + 1
            else
                exit repeat
            end if
        end repeat
        copy newCbFilename to finalCbFilename
        display dialog "Filename already exists " & "File will be named: " & finalCbFilename & ".flv" buttons "OK" default button "OK" with title "Error" with icon caution
    else
        copy cbUsername to finalCbFilename
    end if
end tell

AppleScript – mdfind kMDItemTextContent script to find specified content from display dialog query

Try:

set searchText to text returned of (display dialog "Enter your search text:" default answer "")
set matchText to paragraphs of (do shell script "mdfind \"kMDItemTextContent == " & quoted form of searchText & "\"")
if matchText ≠ {} then
    set targetMatch to (choose from list matchText) as string
    if targetMatch ≠ "false" then tell application "Finder" to open (POSIX file targetMatch) as alias
end if
