I know that I can merge multiple files this way:

osmosis --rx 1.osm --rx 2.osm --rx 3.osm --merge --merge --wx merged.osm


But this way is not very useful if you need merge 200+ files.


Would possible implement something like this?

osmosis --rx  my/files/* --merge --wx  merged.osm
"



It would require significant changes to the way Osmosis works.  With some 
effort, a new --rx task could perhaps be created to write read multiple XML 
files and write them to separate pipes, but a new --merge task would have no
way of knowing how many inputs it should consume.



It's not something I'll personally be tackling.  Can this be solved with a 
wrapper shell script?

Hi,




people on linuxquestions.com helped me with script:




----------

#!/bin/bash

args=()
for osm in "$@" ; do
    args+=(--rx "$osm")
done
for ((i=0; i < $#-1; i++)) ; do
    args+=(--merge)
done
args+=(--wx merged.osm)

osmosis "${args[@]}"

------------*




but I still can't merge files because of this error:
