Having problem changing iphone backup location (following this tutorial https://www.iclarified.com/72786/how-to-change-your-iphone-backup-location-mac)

cannot interpret the error - any help appreciated !

sudo ln -s/Volumes/bbyfrn/Backup ~/Library/Application\ 
ln: illegal option -- /
usage: ln [-Ffhinsv] source_file [link_name]
       ln [-Ffhinsv] source_file ... linkname_dir
       link source_file link_name
  • Be careful how you copy things when you cut and paste and then edit the command you removed a space after -s . I will make a usual comment here only use sudo if you know what the command does - that includes understanding its error messages as sudo can mess up your machine.

You’re missing a space after -s before the path beginning with /.

You can tell this from the error message ‘invalid option’ of / as it’s read the punctuation character as another short option next to s rather than as part of the next argument.

How can I create a symbolic link in Terminal?

Also don’t use sudo — you own the folder in your home directory.

  • Also, it looks above like the Support/MobileSync/Backup part is on a separate line, but in order to work right it must be on the same line as the ln ... ~/Library/Application\ part and there must be exactly one space after the \ and before the Support/... part. Jul 11, 2021 at 0:44
