Split a JSON array into multiple files using command line tools

Suppose we have a JSON array of length 5 and we want to split the array into multiple arrays of length 2 and save the grouped items into different files, using linux command line tools.

I tried it by using the jq and split tools (I am happy with any approach that can be executed from a bash script):

$ echo '[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"},{"key4":"value4"},{"key5":"value5"}]' | jq -c -M '.[]' | split -l 2 -d -a 3 - meta_$ tail -n +1 meta_*==> meta_000 <=={"key1":"value1"}{"key2":"value2"}==> meta_001 <=={"key3":"value3"}{"key4":"value4"}==> meta_002 <=={"key5":"value5"}

The previous command saves the items into the files correctly, but we need to convert them into a valid JSON array format. I tired with --filter option:

$ echo '[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"},{"key4":"value4"},{"key5":"value5"}]' | jq -c -M '.[]' | split -l 2 -d -a 3 - meta2_ --filter='jq --slurp -c -M'[{"key1":"value1"},{"key2":"value2"}][{"key3":"value3"},{"key4":"value4"}][{"key5":"value5"}]$ tail -n +1 meta2_*tail: cannot open 'meta2_*' for reading: No such file or directory

However, it displays the output on the screen but the results aren't persisted. I tried forwarding the output but I get an error:

echo '[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"},{"key4":"value4"},{"key5":"value5"}]' | jq -c -M '.[]' | split -l 2 -d -a 3 - meta2_ --filter='jq --slurp -c -M > $FILE'...split: with FILE=meta2_000, exit 2 from command: jq --slurp -c -M > $FILE

Any hints or better approaches?

EDIT: I tried with double quotes @andlrc suggested:

$ echo '[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"},{"key4":"value4"},{"key5":"value5"}]' | jq -c -M '.[]' | split -l 2 -d -a 3 - meta2_ --filter="jq --slurp -c -M > $FILE"bash: -c: line 0: syntax error near unexpected token `newline'bash: -c: line 0: `jq --slurp -c -M > 'split: with FILE=meta2_000, exit 1 from command: jq --slurp -c -M >$ cat meta_000 | jq --slurp -c -M[{"key1":"value1"},{"key2":"value2"}]
