splitting a pipe delimited file in unix
Could one of you shad some light on this:
I need to split the file by determining the record count and than splitting it up into 4 files. Please note, this is not a fixed record length but rather a "|" delimited file. I am not sure as how to handle reminder/offset for the 4th file. For example: "$1|wc -l" /4 + reminder Please let me know.  |

unix script to split file
My file for ex. is a 10mil record file. Within the shell script I need to determine the record count and divided it into 4 separate files.
Is it ok to do a wc -l into a variable / 4? Would reminder take care of itself - meaning it will be a part of the 4th file. Please advise and I hope this helps. |
