Collapse two or thee bed files into one bed file using bedtools merge

I have a 4 bed files of peak coordinates from ChIP seq, I was wondering is there a way to collapse them into one bed file where all the peak coordinates are now in one bed file from the 4 different files using bedtools merge. And if there is a way what would the command look like. Appreciate any help.

Thank you so much. This is what I was looking for and appreciate your quick response. I did try looking at the documentation of the bedtools merge but was a little confused. Thanks again!
