when running eshell in Windows, i do

c:\Users\xah\web\xxst\make_download_copy>find -name "*el" -exec rm {}
\;
find -name "*el" -exec rm {} \;
find: missing argument to `-exec'

why is it missing argument?

Thanks.

At a guess, you need to quote the {}, like this:

    find -name "*el" -exec rm \{} \;

find gives this error when it doesn't see the ';' argument.
I know of no shell where {} needs to be escaped or quoted.

eshell seems to have difficulties with backslash escapes on
MS-Windows.  Then we could use quotes instead:

   find -name "*el" -exec rm {} ';'

The {} needs to be quoted as well.

none of the suggestions seems to work so far.

c:\Users\xah\Documents\vrici\cabdei>find . -name "*sch*" -exce echo \
{} \;
find . -name "*sch*" -exce echo \{} \;
find: unknown predicate `-exce'

c:\Users\xah\Documents\vrici\cabdei>find . -name "*sch*" -exce echo \
{\} \;
find . -name "*sch*" -exce echo \{\} \;
find: unknown predicate `-exce'

c:\Users\xah\Documents\vrici\cabdei>find . -name "*sch*" -exce echo {}
';'
find . -name "*sch*" -exce echo {} ';'
find: unknown predicate `-exce'

c:\Users\xah\Documents\vrici\cabdei>find . -name "*sch*" -exce echo
'{}' ';'
find . -name "*sch*" -exce echo '{}' ';'
find: unknown predicate `-exce'

this appears to be a bug?

Sorry, i had big typo in the above. This works:

find . -name "*sch*" -exec echo {} ';'

Thanks. Still, this probably should probably be considered a bug. Is
there some technical reason eshell having problems with the \; ?

Yes, there is: you cannot have \ be an escape character on Windows
(without some major annoyances), because it serves as a directory
separator.

Not with bash in eshell on unix.  Perhaps it's needed specifically on MS-Windows?
