I use this powershell script to split my large log files:
$from = "C:\Program Files\Storj\Storage Node\Logs\storagenode.log"
$rootName = "C:\Program Files\Storj\Storage Node\Logs\storagenode.2022.09"
$ext = "log"
$upperBound = 1000MB
$fromFile = [io.file]::OpenRead($from)
$buff = new-object byte[] $upperBound
$count = $idx = 0
try {
do {
"Reading $upperBound"
$count = $fromFile.Read($buff, 0, $buff.Length)
if ($count -gt 0) {
$to = "{0}.{1}.{2}" -f ($rootName, $idx, $ext)
$toFile = [io.file]::OpenWrite($to)
try {
"Writing $count to $to"
$tofile.Write($buff, 0, $count)
} finally {
$tofile.Close()
}
}
$idx ++
} while ($count -gt 0)
}
finally {
$fromFile.Close()
}
Just change the $from and $rootName to your liking and you’ll get 1GB files.
Note - it doesn’t care about lines so will split the files in the middle of a line.
