Open a file which name contains a tilde

@ Gabriel: "Avoid tilde in file names": Not quite. A tilde *suffix* is commonly used by *nix editors for backup files https://unix.stackexchange.com/questions/76189/what-does-the-tilde-mean-at-the-end-of-a-filename
I'm aware of that, but that isn't the case that is being discussed, as the example given clearly had a tilde (and spaces) in the middle of the file. Backup files witilde suffix does not trigger the bug being discussed. It's *only* files paths where the tilde is surrounded on both by spaces (or on the right by the end fo the string) that trigger it.
path.expand("a~b")
[1] "a~b"
path.expand("a ~ b")
[1] "a /Users/gabrielbecker b"
path.expand("myfile.txt~")
[1] "myfile.txt~"
path.expand("myfile.txt ~")
[1] "myfile.txt /Users/gabrielbecker" All that said I'm really not interested in participating in a flame war over this. I gave my 2 cents as respectfully as I could, so as of now please consider my participation and interest in this thread closed. Best, ~G

Note that R treats tildes in file names differently on Windows and
Linux.
On Windows, it is only replaced if it it at the beginning of the line
and
is followed by a forward or backward slash or end-of-line. On Linux
it
is
replaced no matter where it is in the text and ~someUser will be
replaced
by someUser's home directory (if 'someUser' is a user with a home directory).
That's not quite true: On Linux the bug is in the code that uses libreadline, which you don't have to use. If you just specify "--no-readline" when you start R, it will be fine on Linux, as far as I can see.
I wouldn't choose that as the default way to run R (it's pretty irritating not to have readline support), but it is a workaround for this bug.

Hence, if you have a Windows machine that can look at the file system
on
your Linux machine you can use file.rename on Windows to change the
names.
My inclination would be to use a bash script on Linux to change the
names,
but if you are not comfortable with bash try the Windows approach. Bill Dunlap TIBCO Software wdunlap tibco.com On Tue, Jun 11, 2019 at 1:13 PM Frank Schwidom <schwidom at gmx.net>

Hi Gabriel, I actually want to make renames over thousands of files. But if I am

able to express the source filename of the rename operation I will

that R is qualified for solving my problem by the method how it can
handle
long vectors of strings, booleans and also lists. Kind regards, Frank On 2019-06-11 09:49:17, Gabriel Becker wrote:

else is already on the "no tildes in filenames" bandwagon, so this behavior, even if technically a bug, has no ability to cause them problems. Best, ~G On Tue, Jun 11, 2019 at 8:25 AM Frank Schwidom <[1]schwidom at gmx.net

It doesn't seem to be possible if readline is enabled and
works
correctly.
Calls to path.expand [1] end up [2] in R_ExpandFileName
[3],
which
calls R_ExpandFileName_readline [4], which uses
libreadline
function
tilde_expand [5]. tilde_expand seems to be designed to
expand
'~'
anywhere in the string it is handed, i.e. operate on
whole
command
lines, not file paths.
I am taking the liberty of Cc-ing R-devel in case this
can be
considered a bug.
