Re: Can't change directory with shell(cd)
Richard Hillen in September of last year was claiming on this list 25
seconds to do a revcopyfile.
I typed CR into the dictionary and couldn't find it. I think I must
have added an extra " or quote when I was typing.

I haven't done much with copying files. Moving them is very fast using
the rename command, but copying is different. If the files are small
you could try:
put URL ("binfile:" & tOriginalFile) into URL ("binfile:" &
tNewFile)
but if they are larger than a few MB, that might not be so good as it
reads the entire file into memory before writing it out again.
Do you have cr defined as return?
"cr" is defined in Rev. I prefer using it instead of "return" because
"return" also means return a value from a function and I prefer to
make sure they are obviously different. And it's shorter to type :-)

The problem is that you're doing two separate shell calls, each one
evaluated based on the current folder (which is Rev's Home folder). You need
to make a single shell call that does both tasks. For Mac, that means
separating them by semicolons:
put shell("cd /;ls")
This will get a directory listing of the root drive. For Windows, you need
to use an ampersand instead of a semicolon, like this:
put shell("cd c:\ & dir")

Re: Can't change directory with shell(cd)
You can also just set the path to another legal folder.

Do you have cr defined as return? The engine does. I've taken to using it exclusively for "carriage return" because not only is it shorter to type, it helps differentiate it from the "return" command. -- Jacqueline Landman Gay | [EMAIL PROTECTED] HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: Can't change directory with shell(cd)
Yes you do if you have space and other evil MacOS filename
characters. Sarah saw what I was doing wrong.
I wonder if each shell call is threaded separately.
Thanks,

Does the path need to be in quotes? E.g.:

It was the two separate shell calls. I had enclosed file name in

I found 2 problems with this. Firstly, if the folder name contains a
space, this will not work, so I surrounded the aPath with single
quotes. Secondly, I think you are using 2 separate instances of the
shell as you do the commands in two separate shell calls. If you
combine them into a single command and just use one shell call, it
works.
Here is my edited version of your script:
answer folder ""
put it into aPath
put "cd '" & aPath & "'" into aRequest
put aRequest & cr & "ls" into tCmd
put shell(tCmd) into fld 1
However, why do you want to use a shell command for this, when the
same functionality is built into Revolution commands? You could try
something like this:
answer folder ""
put it into aPath
set the defaultfolder to aPath
put the files & cr & the folders into fld 1
