The final working code that can take care of duplicate file names and slashes is this ( be careful this will rename files immediately not a dry-run): for f in *. One more thing is if the first line in the file contains slashes / this is not acceptable and will result in an error so you need to redefine the variable $f1 and change them to underscores _ by adding this line to the code after f1=$(head -n1 "$f"): f1="$" Remove echo for the actual renaming to happen.Īlso note that the actions of the mv options ( -n or -backup=t) will not be reflected in the output while echo is used but will take effect when echo is removed.
If however the first line in each file is not unique, you can make mv append numbers to the new file names if they already exist by using the option -backup=t after mv like so:Ĭhange this line in the above code: echo mv -n "$f" "$f1"Įcho is there to protect your files from unintentional change while testing the code and to give you a dry-run of what will actually happen. That is why I added the option -n after mv to prevent that. The first line in each file must be unique or otherwise some files will get overwritten. When satisfied with the results, remove echo to do the actual renaming like so: for f in *.pgn
Run the above from within the directory containing the files to see a dry-run (no actual renaming will happen). To rename all the files at once, use head to get the first line in the file and mv to rename the file with a for loop like so: for f in *.pgn Only changing of names is required, replacing it with first line of the file content for all 2015 files. But I do not want to change the extension here.
