Batch file rename remove last character code#
Note: The example bash script code is just that and does not contain any additional error handling as may be appropriate. The output of which would be, e.g.: Testing 20-10-03.zip # s = filename suffix (filename without prefix, space, and extension) The example bash script code uses shell parameter expansion to slice and dice the fully qualified pathname of the file(s) passed to it into the necessary pieces and then renames the file(s) using the mv command with the -n option, which will not overwrite an existing file, based on the values of the sliced and diced pieces of the fully qualified pathname.Īs coded, it uses a regex to only act on files that starts with two digits, followed by a dash, followed by two digits, followed by a dash, followed by two digits, followed by a space, followed by additional characters and a file extension, e.g.: 20-10-03 Testing.zipĮxample bash script code: # f = fully qualified pathname Replace the default code of the Run Shell Script action with the example bash script code.If you do choose a Service/Quick Action then set it to use files and folders in Finder.įor the Run Shell Script action, have its settings configured as: If you do a Service/Quick Action, then you only need a Run Shell Script action. The second captured group contains the portion after the last. To move files, use the mv command (man mv), which is similar to the cp command, except that with mv the To copy and rename that file from sneakers. Get Selected Finder Items or Get Specified Finder Items, and then add a Run Shell Script action. Example of removing last 4 characters before file extenstion: -> file.pdf. Select Home > Rename from the Organize group in the ribbon. Or you can select Ctrl+A to select all files as well. If you do just a Workflow, then you will need to add a Files & Folders action, e.g. Select all files in the folder by selecting the first file, holding the Shift key, and then selecting the last file. You can create an Automator Workflow, or Service/Quick Action, workflow. Look at the file again, and when you are positive that it's what you want, execute it with sh /tmp/bulk-rename.Yes, one of the ways it can be done in Automator is by using a Run Shell Script action with the example bash script code shown further below.
That file now contains a lot of lines like mv -n "foo" "bar" mv -n prevents overwriting an existing file. The sed part adds a mv -n to the start of each of those lines. What that paste command does is it takes one line from /tmp/old.txt and one line from /tmp/new.txt and puts them together on one single line with a blank between them. Then put the files together with the paste command and change each line to a mv command: paste /tmp/old.txt /tmp/new.txt | sed -e 's/^/mv -n /' >/tmp/bulk-rename In any case, have a good hard look at /tmp/new.txt to see if it's really what you want the new names to look like.Ĭheck for duplicate names! ( sort /tmp/new.txt | uniq -r) Make sure there are no duplicates and if there are, edit that line manually to get a unique name. Now create a batch file called 'ReNameFile. Important: do not change the order in that file, and do not delete or add any line! Make batch file called 'RunMe.bat' with the following code: Code: dir /b find 'pdf' /i > temp.log set tempvar for /f 'tokens1-2 delims.' /f A in (temp.log) do ( renamefile.bat A B ) del temp.log. For example, if your batch file was named cleancsv.bat you would use the command. where 1 will be the name of the input csv file containing blank lines and 2 will be a new csv file created without blank lines. Then replace unwanted characters in /tmp/new.txt, either manually with an editor or with sed -i -e (or perl -p -i -e if you prefer that) or tr or tr -d. Create a batch file and use the command. it will give you "foo*bar" or "foo | bar". Ls -Q will add double quotes around each name, i.e. In general, mmv is great at mass-renaming tasks.īut in this particular case, I'd go a completely different route: Generate a shell script with a couple of shell commands, have a close look at it if it's really what I want, and then execute it.
