sed: regex input buffer length larger than INT_MAX

I have a big file to which I am doing various operations, and this error just came up. I tried googling it but there didn't find any result with this. sed: regex input buffer length larger than INT_MAX My purpose is to quote every line, appending a comma, and subsequently enclose the entirety of the file with square brackets (as a single line).  For example, an input of The quick brown fox jumps over the lazy dog. should yield a result of ["The quick brown fox","jumps over","the lazy dog.",] Assume that the input file doesn’t contain any quotes. The code I run is this: cat "${FILE}" | sed -e 's/.*/"&",/' | sponge "${FILE}" truncate --size=-1 "${FILE}" cat "${FILE}" | sed -z 's/.*/[&]/' | tr --delete '\n' | sponge "${FILE}" sed version: sed --version sed (GNU sed) 4.5 Any thoughts?
