AppleScript to find and replace in a folder of text files - applescript

I need to replace text in a folder full of text files. How would I go about this?
Thanks!

tell application "Finder"
set l to files of desktop as alias list
end tell
repeat with f in l
set input to read f as «class utf8»
set text item delimiters to "search"
set ti to text items of input
set text item delimiters to "replace"
set b to open for access f with write permission
set eof b to 0
write (ti as text) to b as «class utf8»
close access b
end repeat
I mostly just use find in project in TextMate or Ruby scripts like this:
Dir["#{ENV['HOME']}/Desktop/*"].each do |f|
input = File.read(f).gsub(/search/, "replace")
File.open(f, "w") { |f| f.print(input) }
end
You could also use sed:
sed -i '' 's/search/replace/g' ~/Desktop/*

Using Applescript to scan a volume, pull out the path, file name and a number and output results csv

I have been at this for two days.
So, using Automator and Applescript, I need to scan a volume (or volumes) and get a path to each file, the file name plus extension, assetID (if there is one) and output each part to a comma separated csv file.
So far, I have the Automator actions sorted out and most of the Applescript part but I am at my wits end. The paths and file names work but extracting the assetID (if there is one) is the problem. Not every file has an assetID (and those I am not interested in). The assetID is always a 10 digit number at the end of the file preceded by an underscore("_") like so - afilename_1234567890.ext. As it is now, the script will display the assetID's of the files it processes but as soon as it gets to a file with no id, I see the following error, "The action “Run AppleScript” encountered an error: Can’t get text 1 thru -1 of "".” Something is getting munged somewhere.
Any help would be greatly appreciated.
The script so far...
on run {input, parameters}
-- save delimiters to restore old settings
set savedDelimiters to AppleScript's text item delimiters
-- set delimiters to delimiter to be used
set AppleScript's text item delimiters to "/"
repeat with aPath in input
-- set a variable to contain the "/" (POSIX) version of the files path
set filesPath to POSIX path of aPath
-- get the file name
set fileName to last text item of filesPath
-- get the file name without the extension
set thePrefix to text 1 thru ((offset of "." in fileName) - 1) of fileName
-- get the asset ID, if there is one
set assetID to rightStringFromRight(thePrefix, "_")
display dialog assetID
if (class of assetID) is integer then
-- get the path only
set pathOnly to ((text items 1 thru -2 of (get POSIX path of aPath)) as Unicode text) & "/"
-- output the path only, file name and asset ID to a comma delimited csv file
display dialog assetID
end if
end repeat
-- restore the old delimiter setting
set AppleScript's text item delimiters to savedDelimiters
end run
on rightStringFromRight(str, del)
local str, del, oldTIDs
set oldTIDs to AppleScript's text item delimiters
try
set str to str as string
if str does not contain del then return str
set AppleScript's text item delimiters to del
set str to str's last text item
set AppleScript's text item delimiters to oldTIDs
return str
on error eMsg number eNum
set AppleScript's text item delimiters to oldTIDs
error "Can't rightStringFromRight: " & eMsg number eNum
end try
end rightStringFromRight
on is_number(number_string)
try
set number_string to number_string as number
return true
on error
return false
end try
end is_number
I finally got the script working. A few wrong assumptions corrected and all is well.

Using AppleScript to compare filenames without extensions in two directories

To preface, I made a Photoshop batch action which converts a folder with thousands of images in different formats into .pngs. Unfortunately some of them were skipped and others converted with the wrong aspect ratio.
I'm hoping to compare the folders using Applescript. At the moment I just want to find which files made it through and which didn't. I'd like the user to be able to select the source and converted folders, and then need to strip the file extension to compare the filenames in each folder. Here's what I have written so far; it seems to stop right after the end tell statement. What am I doing wrong?
--Set folder paths
display dialog "Choose the source folder containing images with correct aspect ratios"
set source_folder to (choose folder)
display dialog "Choose the folder containing PNGs to compare to"
set png_folder to (choose folder)
--Create lists of folder contents for each folder
tell application "System Events"
set source_filenames to name of every file of source_folder
set source_extensions to name extension of every file of source_folder
set png_filenames to name of every file of png_folder
set png_extensions to name extension of every file of png_folder
end tell
--Collect names (filename minus dot and extension)
set source_names to {}
repeat with n from 1 to count of source_filenames
set source_filename to item n of source_filenames
set source_extension to item n of source_extensions
if source_extension is not "" then
set source_filename_length to (count of source_filename) - (count of source_extension) - 1
set end of source_names to text 1 thru source_filename_length of source_filename
else
set end of source_names to source_filename
end if
end repeat
return source_names
set png_names to {}
repeat with n from 1 to count of png_filenames
set png_filename to item n of png_filenames
set png_extension to item n of png_extensions
if png_extension is not "" then
set png_filename_length to (count of png_filename) - (count of png_extension) - 1
set end of png_names to text 1 thru png_filename_length of png_filename
else
set end of png_names to png_filename
end if
end repeat
return png_names
--Compare each item of source folder to png folder
repeat with n from 1 to the count of source_names
set theFile to (item n of source_names)
if theFile is in png_names then
log "Match found for file " & theFile
set foundFile to true
else
log "No match found for file " & theFile
set foundFile to false
end if
end repeat
Later, I'll want to compare aspect ratios (using this thread as a guide http://macscripter.net/viewtopic.php?id=38308) and have all the files which either didn't get converted or were converted with the incorrect aspect ratio put into some sort of list.
Thanks for your help! :)
Solved it myself! Shouldn't be returning source_names/png_names.

AppleScript for change file names inside folders

I need to write an AppleScript that can change my files names inside folder.Below is my scenario.
Folder1
|
Folder2
|
imageA.png,imageB.png
Now i need to write an AppleScript that can change name of imageA.png to A.png and imageB.png to B.png.
What should be my AppleScript for this? this is not my exact scenario but i am giving an example above so i can implement more from that.
I have tried below script and it is working well but i am getting error when filename is not exist, means it is not ignoring it.
tell application "Finder"
set the name of file "iOs_142:About1.png" to "About1.png"
set the name of file "iOs_142:FAQs.png" to "FAQs1.png"
end tell
If you really insist on doing this with AppleScript, this should give a template to work forward with:
(* Taken from http://applescript.bratis-lover.net/library/string/#replaceString *)
on replaceString(theText, oldString, newString)
local ASTID, theText, oldString, newString, lst
set ASTID to AppleScript's text item delimiters
try
considering case
set AppleScript's text item delimiters to oldString
set lst to every text item of theText
set AppleScript's text item delimiters to newString
set theText to lst as string
end considering
set AppleScript's text item delimiters to ASTID
return theText
on error eMsg number eNum
set AppleScript's text item delimiters to ASTID
error "Can't replaceString: " & eMsg number eNum
end try
end replaceString
tell application "Finder"
set fs to files of folder POSIX file "/your/folder" as list
end tell
repeat with f in fs
set n to replaceString(name of f, "to be replaced", "")
tell application "System Events" to set name of f to n
end repeat

Multiple if conditions within nested repeat while in applescript

I've never used AppleScript before, so i'm quite unfamiliar with the language, but i'm doing my best.
Here's what i'm trying to accomplish:
Run a script while selecting a folder filled with .ARW and .JPG files. Iterate through the items in the folder. If the current item is .ARW, iterate through the folder starting from the beginning again. If this nested iteration lands on a file that has the same file name and a JPG extension, label the original ARW file with red.
TLDR: If an ARW file in a folder shares the same filename as a JPG file in the folder, highlight the ARW file in red, otherwise do nothing.
Here's the code i've written so far:
tell application "Finder"
set totalAlias to the entire contents of (selection as alias)
set totalCount to the count of items of totalAlias
set firstName to name of item 1 of totalAlias
set firstExtension to name extension of item 1 of totalAlias
set c to 1
repeat while c ≤ totalCount
set currentAlias to item c of totalAlias
set currentName to name of currentAlias
set currentExtension to name extension of currentAlias
if currentExtension is "ARW" then
set d to 1
set compareFile to currentAlias
set findName to currentName
set findExtension to currentExtension
repeat while d ≤ totalCount
if (name of item d of totalAlias = findName) and (name extension of item d of totalAlias is "JPG") then
tell application "Finder" to set label index of compareFile to 2
end if
set d to (d + 1)
end repeat
end if
set c to (c + 1)
end repeat
end tell
Any thoughts on what's going wrong? I believe it has to do with my IF AND condition.
Try this script:
tell application "Finder"
--Just get all the filenames of the target types:
set allJPG to the name of every file of (entire contents of (selection as alias)) whose name extension = "JPG"
set allARW to the name of every file of (entire contents of (selection as alias)) whose name extension = "ARW"
--Send the two lists to a handler to find all the common names
set targetJPGFiles to my CompareNames(allJPG, allARW)
--Loop through the common names, find the files, set the tags
repeat with eachTarget in targetJPGFiles
set fileToTag to (item 1 of (get every file of (entire contents of (selection as alias)) whose name is (eachTarget as text)))
set label index of fileToTag to 2
end repeat
end tell
targetJPGFiles -- This allows you to see the filenames that SHOULD have been tagged
to CompareNames(jp, pn)
--First, get rid of all the extensions in the ARW files
set cleanARWNames to {}
set neededJPGNames to {}
repeat with eachARWName in pn
set end of cleanARWNames to characters 1 thru -5 of (eachARWName as text) as text
end repeat
--Now, loop through JPG names to find a match
repeat with eachjpgName in jp
set searchName to characters 1 thru -5 of (eachjpgName as text) as text
if cleanARWNames contains searchName then
set end of neededJPGNames to (eachjpgName as text)
end if
end repeat
return neededJPGNames
end CompareNames
It takes a slightly different approach, in that it just compares two lists of filenames only, then goes back, finds the files with the names you want, and does the tagging.
It is based on a script I wrote for another project, so I hope it works for you.
I have never used the label index property in Finder before, and I found through some testing that I could not see the labels until I clicked on the folder after the script ran. All the target files had the correct tag after I did that, though.

Applescript: Get filenames in folder without extension

I can get the names of all files in a folder by doing this:
tell application "Finder"
set myFiles to name of every file of somePath
end tell
How can I change the strings in myFiles so that they do not include the file extension?
I could for example get {"foo.mov", "bar.mov"}, but would like to have {"foo", "bar"}.
Current solution
Based on the accepted answer I came up with the code below. Let me know if it can be made cleaner or more efficient somehow.
-- Gets a list of filenames from the
on filenames from _folder
-- Get filenames and extensions
tell application "Finder"
set _filenames to name of every file of _folder
set _extensions to name extension of every file of _folder
end tell
-- Collect names (filename - dot and extension)
set _names to {}
repeat with n from 1 to count of _filenames
set _filename to item n of _filenames
set _extension to item n of _extensions
if _extension is not "" then
set _length to (count of _filename) - (count of _extension) - 1
set end of _names to text 1 thru _length of _filename
else
set end of _names to _filename
end if
end repeat
-- Done
return _names
end filenames
-- Example usage
return filenames from (path to desktop)
From http://www.macosxautomation.com/applescript/sbrt/index.html :
on remove_extension(this_name)
if this_name contains "." then
set this_name to ¬
(the reverse of every character of this_name) as string
set x to the offset of "." in this_name
set this_name to (text (x + 1) thru -1 of this_name)
set this_name to (the reverse of every character of this_name) as string
end if
return this_name
end remove_extension
Single line way of doing it, no Finder, no System Events. So more efficient and faster. Side effect (could be good, or bad): a file name ending with "." will have this character stripped out. Using "reverse of every character" makes it works if the name as more than one period.
set aName to text 1 thru ((aName's length) - (offset of "." in ¬
(the reverse of every character of aName) as text)) of aName
The solution as a handler to process a list of names:
on RemoveNameExt(aList)
set CleanedList to {}
repeat with aName in aList
set the end of CleanedList to text 1 thru ((aName's length) - (offset of ¬
"." in (the reverse of every character of aName) as text)) of aName
end repeat
return CleanedList
end RemoveNameExt
Here's an applescriptish method to get Finder's idea of what the stripped filename is but please note it will only work if you have NOT enabled the option in Finder's preferences to "Show all filename extensions":
set extension hidden of thisFile to true
set thisName to displayed name of thisFile
-- display dialog "hey"
set extension hidden of thisFile to false
Here's a full script that does what you wanted. I was reluctant to post it originally because I figured there was some simple one-liner which someone would offer as a solution. Hopefully this solution is not a Rube Goldberg way of doing things.
The Finder dictionary does have a name extension property so you can do something like:
tell application "Finder"
set myFiles to name extension of file 1 of (path to desktop)
end tell
So the above will get you just the extension of the first file on the user's desktop. It seems like there would be a simple function for getting the (base name - extension) but I didn't find one.
Here's the script for getting just the filenames without extension for every file in an entire directory:
set filesFound to {}
set filesFound2 to {}
set nextItem to 1
tell application "Finder"
set myFiles to name of every file of (path to desktop) --change path to whatever path you want
end tell
--loop used for populating list filesFound with all filenames found (name + extension)
repeat with i in myFiles
set end of filesFound to (item nextItem of myFiles)
set nextItem to (nextItem + 1)
end repeat
set nextItem to 1 --reset counter to 1
--loop used for pulling each filename from list filesFound and then strip the extension
--from filename and populate a new list called filesFound2
repeat with i in filesFound
set myFile2 to item nextItem of filesFound
set myFile3 to text 1 thru ((offset of "." in myFile2) - 1) of myFile2
set end of filesFound2 to myFile3
set nextItem to (nextItem + 1)
end repeat
return filesFound2
Though the above script does work if anyone knows a simpler way of doing what the OP wanted please post it cause I still get the sense that there should be a simpler way of doing it. Maybe there's a scripting addition which facilitates this as well. Anyone know?
Based on Lauri Ranta's nice solution, which works for extensions that Finder doesn't know about:
set delims to AppleScript's text item delimiters
set AppleScript's text item delimiters to "."
set myNames to {}
tell application "Finder"
set myFiles to name of every file of (path to Desktop)
repeat with myfile in myFiles
set myname to name of file myfile
if myname contains "." then set myname to (text items 1 thru -2 of myname) as text
set end of myNames to myname
end repeat
end tell
set AppleScript's text item delimiters to delims
return myNames
I don't know how to remove the extensions when you use the "every file"
syntax but if you don't mind looping (loop not shown in example) through each file then this will work:
tell application "Finder"
set myFile to name of file 1 of somePath
set myFile2 to text 1 thru ((offset of "." in myFile) - 1) of myFile
end tell
Within a tell "Finder" block this collects file names stripped of the extension in myNames:
repeat with f in myFiles
set myNames's end to ¬
(f's name as text)'s text 1 thru -(((f's name extension as text)'s length) + 2)
end repeat
For a single file I found the answer here, copied below.
set theFileName to "test.jpg"
set thePrefix to text 1 thru ((offset of "." in theFileName) - 1) of theFileName
This is a little more than you need, but it will handle more than one "." in a file name.
Assuming that a file alias is passed in to the method.
on Process(myFileAlias)
set myFile to myFileAlias as string
set AppleScript's text item delimiters to ":"
set myItemCount to the number of text items in myFile
set myFileName to the last text item of myFile
set myFilePath to text items 1 through (myItemCount - 1) of myFile
set AppleScript's text item delimiters to "."
set myItemCount to the number of text items in myFileName
set myExtension to the last text item of myFile
// This line is the key.
set myShortFilename to text items 1 through (myItemCount - 1) of myFileName as string
log (myFileName)
log (myShortFilename)
end
