ffmpeg: no matches found: -map[v]

I am trying to merge 4 videos in split-screen with their audio together.

./ffmpeg -i ./clip11.mp4 -i ./clip21.mp4 -i ./clip31.mp4 -i ./clip41.mp4  -filter_complex "[0:v][1:v]hstack=inputs=2[top];[2:v][3:v]hstack=inputs=2[bottom];[top][bottom]vstack=inputs=2[v];amerge=inputs=4[a]" -map[v] -map[a] ./split21.mp4

I try tried and run the code, but it shows this as an error.

zsh: no matches found: -map[v]

I don't know whether my machine cannot configure the "map" because it happens the same thing when I tried to do "concat". I do not know what else to change about. I typed it out on the latest Mac, but surprisingly my friend that have an older version of Mac got the code working. Help.

Looks like it's zsh that complains that a file pattern is not matching any file. Try to add a space and put quotes around the patterns like this -map "[v]" -map "[a]" to no expand them.

You are missing some spaces to separate the option from the value.

Use -map "[v]" -map "[a]".

The quotes are not necessary in this case but will allow you to use spaces in your label names if desired.
