@K7AAY do csv files have 'n' at the end, should i just readline 100 times and write it to another file?

Windows and DOS use carriage return and line feed ("rn") as a line ending, which Unix uses just line feed ("n").

Depending on what you want you can:
Take the 1st 100 rows as suggested by @K7AAY.
head -n100 filename.csv > file100.csvTake the last 100 rows
tail -n100 filename.csv > file100.csvTake a random selection of 100 rows. This requires you have the GNU
shufprogram installed. It should be installable from your distribution's repositories if you're on Linux.shuf -n100 filename.csv > file100.csvAlternatively, if your
sortsupports the-R(random sort) option, you can do:sort -R filename.csv | head -n100 > file100.csv

Use head to display only the first 100 lines and direct them to a new file. Please substitute the current file name for filename.csv:
head -n100 filename.csv > file100.csv
