That's using CPI, which I always think of as a con by our Government to

Hi Clive,

No, a mount point is a directory where the filesystem's root directory
appears, e.g. /home is a common one. Whilst it's mounted, the contents
of the original /home directory are inaccessible as accesses pass across
to the

Now to me, it's more logical to tinker with the file descriptors of the
command first and then say where they are going rather than vice versa.
On a related note I recall early *nixes where the command switches had to
precede all the other arguments. Took me years to get used to the fact that

I expect Bob used ldd(1) and then removed common ones by hand, knowing
what they were likely to be. For a one-off quick task, automating it
would be more tedious.

You reminded me that a few days ago I listed the files in a core package on
a server (looking for a missing utility) and saw a few things in the list
that I didn't immediately recognise. I thought at the time, "That would be
a good way to learn about utilities that I don't know exist".

But you did it anyway, even though you didn't need the results!
(Don't change, your code snippets are great.)

Thanks Ralph and Patrick.

Well we live and learn. I'm going to add this to my catalogue of scenarios
where I have developed a muscle-memory for doing things an 'old' way, and

Hi Ralph,
Neat trick with ix.io; I hadn't met that before. A pastebin for one-liners!
I was puzzled to see the '&' in your command above. I'd have thought that
saying
(yada yada) | curl -sSF 'f:1=<-' ix.io
would do the trick, and that adding the ampersand would, if anything, cause
it to break:

Hi Victor,
Hope life's treating you well since you moved ‘abroad’.

Patrick's answered that ‘|&’ is a bash shorthand for ‘2>&1 |’.
