A small Go utility application for splitting a large file (think gigabytes) into smaller ones.
-b uint
Customize buffer size. (default 10000000)
-d string
Provide a directory path where partial files will be stored (default "parts")
-f string
Provide a relative path to file you wish to split.
-l uint
Line limit per part-file. (default 10)
-p string
Provide a prefix for each part. (default "part_")
-s string
Provide a suffix for each part.
-crlf bool
Use CRLF instead of LF for line endings.
Let's say you have a file bigfile.sql of, let's say, 100gb in size. It contains queries you might want to execute, but there might be an error in one of the lines.
You try to open it in Notepad to see what's up, but the thing won't open. It won't load such a big file.
Damn it! Happens every time, right? Well, how about splitting it into thousands (or more) (or less?) of files and examining each one of them?
In your particular case, this command will solve your 100th life problem, so you're left with just 99.
go run main.go -f bigfile.sql
Now you see that a new folder parts is created in the directory where your bigfile.sql is.
It starts getting populated with files such as part_1.sql, part_2.sql, etc...
Congratulations! Now you've got 99 problems but a bigfile.sql ain't one.
