I have a rather large .msg file formatted in the UIEE format.
$ wc -l big_db.msg 8726593 big_db.msg
Essentially, the file is made up of entries of various length that look something like this:
UR|1 AA|Condon, Richard TI|Prizzi's Family CN|Collectable- Good/Good MT|FICTION PU|G.P. Putnam & Sons DP|1986 ED|First Printing. BD|Hard Cover NT|0399132104 KE|MAFIA KE|FICTION PR|44.9 XA|4 XB|1 XC|BO XD|S UR|10 AA|Gariepy, Henry TI|Portraits of Perseverance CN|Good/No Jacket MT|SOLD PU|Victor Books DP|1989 BD|Mass Market Paperback NT|1989 tpb g 100 meditations from the Book of Job "This book...help you NT| persevere through the struggles of your life..." KE|Bible KE|religion KE|Job KE|meditations PR|28.4 XA|4 XB|5 XC|BO XD|S
This is an examples of two entries, separated by a blank line. I wish to split this big file into smaller files without breaking an entry into two files.
Each individual entry is separated by a newline (a completely blank line) in the file. I wish to break this 8.7 million line file into 15 files. I understand that tools like
split exist but I'm not quite sure how to split the file but only have it split on a newline so a single entry doesn't get broken into multiple files.
