You are right, you need to quote the space to make it a single
argument for bash:

parallel -v touch {1}\; bash -c ls\\\ {2} ::: "my file" ::: "-l -a"

Or:

parallel -v touch {1}\; bash -c 'ls\ '{2} ::: "my file" ::: "-l -a"

It is starting to look ugly. Maybe I should re-introduce the option
for not having the arguments quoted. It The combined (above) will
still look the same but the non-combined would look like:

parallel -v --no-quoting ls {} ::: "-l -a"

which might be easier to read. The option was removed 20101129.
