32 .Nd split files based on context
44 into pieces using the patterns
52 reads from standard input.
54 The options are as follows:
55 .Bl -tag -width indent
57 Give created files names beginning with
62 Do not remove output files if an error occurs or a
71 of decimal digits after the
73 to form the file name.
76 Do not write the size of each output file to standard output as it is
82 operands may be a combination of the following patterns:
83 .Bl -tag -width indent
86 .Cm / Ar regexp Cm / Op Oo Cm + | - Oc Ar offset
89 Create a file containing the input from the current line to (but not including)
90 the next line matching the given basic regular expression.
93 from the line that matched may be specified.
96 .Cm % Ar regexp Cm % Op Oo Cm + | - Oc Ar offset
99 Same as above but a file is not created for the output.
101 Create containing the input from the current line to (but not including)
102 the specified line number.
103 .It Cm { Ns Ar num Ns Cm }
104 Repeat the previous pattern the specified number of times.
105 If it follows a line number pattern, a new file will be created for each
110 The first line of the file is line number 1 for historic reasons.
113 After all the patterns have been processed, the remaining input data
114 (if there is any) will be written to a new file.
116 Requesting to split at a line before the current line number or past the
117 end of the file will result in an error.
120 .Ev LANG , LC_ALL , LC_COLLATE
123 environment variables affect the execution of
134 into one file for each section (up to 20):
136 .Dl "csplit -k foo.1 '%^\e.Sh%' '/^\e.Sh/' '{20}'"
138 Split standard input after the first 99 lines and every 100 lines thereafter:
140 .Dl "csplit -k - 100 '{19}'"
