I want to count the amount of lines in a CSV file. But only those with "<" at the beginning.

Use grep with c:

grep -c '^<' <FILE>

Use the awk, Luke:

$ cat file
foo
< this foo
not this foo <
< another of those foos
$ awk '/^</{c++}END{print c}' file

You can get all the line containing '<' at the begining with grep '^<' and count remaining line with wc -l.

grep "^<" file.csv | wc -l

grep -E "^<" filename | wc -l

Use regular expressions with grep to check for < at the start of the line (^) and then pipe through wc -l to get number of lines.
