I am using an R package. The input files required to run in the the package are large(as big as 65 Gb of size) So I have decided to split the file in chunks based on line number and then merge the Final Output into a single file. Also I want to do the whole process in PERL.

How should I go about writing a code for the same?

  • I need to calculate something in each line of the chunk files.@αғsнιη – user8393448 Jan 25 '18 at 11:08

split -l numberoflines inputfile

Huge file will splitted as xaa,xab,xac and so on

finally you can concatenate as cat xa* >> final_output_file

If i want to split file for every 65 lines then use below command

example

split -l 65 inputfile
