NAME
split, fsplit - split a file into pieces
SYNOPSIS
split [ -n | -e expression ] [ -f fileroot ] [ -x ] [ -y ] [ -s suffix
] [ file ]
fsplit [ option ] ... [ file ] ...
DESCRIPTION
Split reads file (standard input by default) and writes it in n-line
pieces (default 1000), as many as necessary, onto a set of output
files. The name of the first output file is fileroot (default x) with
aa appended, and so on lexicographically.
If one or more expressions are specified, the file divisions occur at
each line of file which matches an expression; line counts are irrele‐
vant. The expressions are identical to those of grep(1). If a subex‐
pression of expression is contained in escaped parentheses \(...\), the
file name for the output file is the portion of the line which matches
the subexpression, optionally suffixed by a string specified with the
-s option.
The first line of each output file is the matching input line, but it
may be excluded from the output file by setting the -x flag. The -y
flag causes lower case letters in expression to match either case of
letter in the input, but any output file names (excluding the suffix)
will be forced to lower case.
Fsplit splits a collection of Fortran subprograms in one file into sep‐
arate files. Options -f, -e, and -r set the file suffix: procedure
`proc' will go into file `proc.f' (default), `proc.e', or `proc.r' ac‐
cordingly. Block data subprograms will go into files named `BLOCK‐
DATA1.f', etc.
Option -s strips off data beyond column 72 together with any resulting
trailing blanks.
