CSPLIT ( 1) CSPLIT ( l )
Regular expressions may not contain embedded new-lines. Csplit
does not affect the original file; it is the users responsibility to
remove it.
EXAMPLES
csplit -f cobol file '/procedure division/' jpar5./ jpar16./
This example creates four files, cobolOO • • • cobol03. After
editing the "split" files, they can be recombined as follows:
cat cobol0[0-3] > file
Note that this example overwrites the original file.
csplit -k file 100 {99}
This example would split the file at every 100 lines, up to 10,000
lines. The -k option causes the created files to be retained if
there are less than 10,000 lines; however, an error message would
still be printed.
csplit -k prog.c '%main(%' '/'}/+11 {20}
Assuming that prog.c follows the normal C coding convention of
ending routines with a } at the beginning of the line, this example
will create a file containing each separate C routine (up to 21) in
prog.c.

DIAGNOSTICS
Self explanatory except for:
arg - out of range
which means that the given argument did not reference a line
between the current position and the end of the file.
