33 .Nd split files based on context
45 into pieces using the patterns
53 reads from standard input.
55 The options are as follows:
56 .Bl -tag -width indent
58 Give created files names beginning with
63 Do not remove output files if an error occurs or a
72 of decimal digits after the
74 to form the file name.
77 Do not write the size of each output file to standard output as it is
83 operands may be a combination of the following patterns:
84 .Bl -tag -width indent
87 .Cm / Ar regexp Cm / Op Oo Cm + | - Oc Ar offset
90 Create a file containing the input from the current line to (but not including)
91 the next line matching the given basic regular expression.
94 from the line that matched may be specified.
97 .Cm % Ar regexp Cm % Op Oo Cm + | - Oc Ar offset
100 Same as above but a file is not created for the output.
102 Create containing the input from the current line to (but not including)
103 the specified line number.
104 .It Cm { Ns Ar num Ns Cm }
105 Repeat the previous pattern the specified number of times.
106 If it follows a line number pattern, a new file will be created for each
111 The first line of the file is line number 1 for historic reasons.
114 After all the patterns have been processed, the remaining input data
115 (if there is any) will be written to a new file.
117 Requesting to split at a line before the current line number or past the
118 end of the file will result in an error.
121 .Ev LANG , LC_ALL , LC_COLLATE
124 environment variables affect the execution of
133 into one file for each section (up to 20):
135 .Dl "csplit -k foo.1 '%^\e.Sh%' '/^\e.Sh/' '{20}'"
137 Split standard input after the first 99 lines and every 100 lines thereafter:
139 .Dl "csplit -k - 100 '{19}'"
