Split the file into lines

[Dorik]

The script splits the file into the required number of lines and saves it into a new file.

#~*~ coding: utf-8 ~*~

# Open file
src = open("links.txt", "r")
i = 0
line_i = 0
dest_str = "links_%s.txt"

# maximum lines count for each new file
max_lines_count = 1000

# read lines
lines = src.readlines()
src.close()

# open new file "links_0.txt"
f = open(dest_str % i, "w+")

# for each line
for line in lines:
    # if lines count in new file is 1000
    if line_i == max_lines_count:
        # clise created file
        f.close()
        i += 1
        # create new file
        f = open(dest_str % i, "w+")
        line_i = 0
        print("creating file %s\n" % (dest_str % i))
    # write line in file
    f.write(line)
    line_i += 1

f.close()

split -l <max_lines_count> --numeric-suffixes <input_file>

Demo:
split -l 1000 --numeric-suffixes huge_file.txt

Result files:
x01 x02 x03 ....
