I want to copy a file to another disk, when completed delete it, and create a symlink back to it in the original location.

example: copyandlink.sh somefile.iso

#!/bin/bash
set -e
cp $1 /media/storage/linked/ &&
rm $1 &&
ln -s /media/storage/linked/$1 ./

or something like that.

    You do know that hard links cannot work across devices, don't you? – AlexP Jan 2 '17 at 0:39
  • Since the current question is impossible to answer, as pointed out by AlexP, you can either change it to use soft links or similar alternatives, or delete it. – Julie Pelletier Jan 2 '17 at 4:48
  • My mistake, confusing hardlinks and symlinks. – jakethedog Jan 3 '17 at 1:00
  • So what is the question that remains? – icarus Jan 3 '17 at 5:45
  • Maybe this is as good as it gets, but it is not very elegant. I thought there would be a better, more robust way. – jakethedog Jan 3 '17 at 6:10

You're on the right track since your script does exactly what you want.

It can be simplified and improved a little like:

#!/bin/bash
mv $1 /media/storage/linked/ &&
ln -s /media/storage/linked/$1 .

The set -e has no impact since your commands are already conditional with the &&.

I also replaced the cp and rm for mv which handles both automatically, whether on the same partition or not.
