The answer would seem to be to pass the arguments to mv without performing
expansion, but this is very tricky to get right and I have been unable to
devise a reliable way of doing it thus far.
- colons make completion go awry
bash gives special treatment to a colon in command lines. Although this
is not documented, a colon basically starts a new completion token. This
is often useful behaviour, as it allows a completion to work in a command
like the following:
$ export PATH=/bin:/sbin:/usr:/usr/<Tab>
If bash did not treat the colon (and, incidentally, the '=') as special,
bash would try to complete on the single token '/bin:/sbin:/usr:/usr/'.
However, this behaviour is less desirable when performing a command such
as this:
$ scp foo.txt user@machine:<Tab>
Here, scp is receiving two arguments, but the presence of the colon
confuses the completion function into thinking that it needs to perform
completion for the last token from scratch, so you end up with nonsensical
completions.
The special treatment of the colon cannot be turned off in bash, so the
only way to work around this problem is to escape the colon with a
backslash when you want it to be treated as a normal character.
