Hi.
The demonstration script assumes groups of 2, it is not generalized. You would need to change the split command or modify the script to accept another parameter in addition to the input file name to obtain a different number of sequences in the final set of files.
However, the script as it stands will accept (but ignore) parameters beyond the file name. For example, we can copy the default input file file name, data1, to another file, my-input-test, and run that:
Code:
% cp data1 my-input-test
% ./s1 my-input-test 324
producing the output:
Code:
% ./s1 my-input-test 324

Hi,
I have received a file which is 20 GB. We would like to split the file into 4 equal parts and process it to avoid memory issues.
If the record delimiter is unix new line, I could use split command either with option l or b.
The problem is that the line terminator is |##|

Hi;
I want to write a shell script that will split a string with no delimiter.
Basically the script will read a line from a file.
For example the line it read from the file contains:
99234523
These values are never the same but the length will always be 8.
