Comment on mv *.jpg is complete bullshit.

I expected people have tried to move files… using the move command.

I did not expect I’d have to specify that there’s a destination, in an explanation of what *.jpg does, not an explanation of what mv does.

For clarity:

GNU bash, version 5.0.17(1)-release (x86_64-pc-linux-gnu)

mv *.jpg /mnt/Example/Pictures

Where it will then die with an error like mv: invalid option – ‘1’ depending on the contents of the current directory.

Every search about this has led back to this StackOverflow page sooner or later. All answers address wildcard expansion.

When I run into situations like this, I use the commands that work to write out a script. Eg, in your case the wildcard isn’t working with the mv command, so do something like this:

ls -1 *.jpg | awk ‘{print “mv "“$1”" /mnt/example/Pictures”}’ > /tmp/movefiles.sh

Then check the movefiles.sh and make sure it has all of the commands and files properly stated, make that executable, and then run that.

  ls | grep | mv would work, except the StackOverflow discussion also highlights how parsing ls can have the same issues.
  
  I am moving thousands of files at once. If I have to check each one, it’s still wrong.
  
  The pragmatic answer turns out to be ./* instead of *.

    I saw that answer and was just offering another option. I am sure xargs might work, but you would need to test as you need a destination passed on each line. Back to my way, I have used it for a lot more than just the move command. I think I used it to do a chmod once where I wanted to check and make sure before I committed to actually running the command(s). You could also use find and the -exec option, which I think was also mentioned here.

Can you run printf %s\\n *.jpg in that same directory and share the result? I’m really intrigued. If there’s private information in there, I’d be satisfied with just a handful of lines with private info replaced with ****s

  printf %s\\n *.jpg is just a list of filenames on newlines. There’s 75,000 of them. You’ll have to take my word for it.
  
  Fortunately, GenderNeutralBro’s aside about using ./* instead of * works as expected. Could have been files beginning with _-. None begin with -, exactly.
