989b50d902SRodney W. GrimesIf additional arguments are specified, the first is used as the name
999b50d902SRodney W. Grimesof the input file which is to be split.
1009b50d902SRodney W. GrimesIf a second additional argument is specified, it is used as a prefix
1019b50d902SRodney W. Grimesfor the names of the files into which the file is split.
1029b50d902SRodney W. GrimesIn this case, each file into which the file is split is named by the
10341850495SMike Barcroftprefix followed by a lexically ordered suffix using
10441850495SMike Barcroft.Ar suffix_length
10541850495SMike Barcroftcharacters in the range

1129b50d902SRodney W. Grimes.Ar name
1139b50d902SRodney W. Grimesargument is not specified, the file is split into lexically ordered
11441850495SMike Barcroftfiles named with prefixes in the range of
11541850495SMike Barcroft.Dq Li x-z
11641850495SMike Barcroftand with suffixes as above.
1179b50d902SRodney W. Grimes.Sh BUGS
1189b50d902SRodney W. GrimesFor historical reasons, if you specify
1199b50d902SRodney W. Grimes.Ar name ,
1208fe908efSRuslan Ermilov.Nm
1219b50d902SRodney W. Grimescan only create 676 separate
1229b50d902SRodney W. Grimesfiles.
1239b50d902SRodney W. GrimesThe default naming convention allows 2028 separate files.
12441850495SMike BarcroftThe
