Backup files in internet recovery mode: cp command errors
The error has to be in the names of the directory structures you use. For example, using the last command the error must be in the names
&quot;/Volumes/Macintosh HD/Users/myusername/Pictures/&quot;
or
&quot;/Volumes/nameofextHD/&quot;
There is a problem with one of these names or else there are no jpgs in that directory.
The same applies for the other statements. Did you mean to use the -r or the -R option with the copy command? My computer running High Sierra doesn't show a -r option for the cp command. I think you want -R.
