sed counting lines incorrect

Running sed for counting lines in my file returns 1, but Sublime and Textedit count more than 88000 lines. Why does sed do that? How can I fix it?

$sed -n '$=' out_data1.txt
1

I use sed to count lines of a very large file ~10GB of mongodb query result to split it later for multithread.

sed have some buffer limit but try (i don't recommand sed on huge file especially just for counting lines)

sed -u -n "$="

maybe a "s/.*//;$=" if there is also a buffer problem on line size itself

You command should work, but try:

wc -l out_data1.txt

or just for test

awk 'END {print NR}' data1.txt
