csplit(1) General Commands Manual csplit(1) NAME
csplit - context split SYNOPSIS
prefix] number] file arg1 [...argn] DESCRIPTION
reads file, separates it into n+1 sections as defined by the arguments arg1 ... argn, and places the results in separate files. The maxi- mum number of arguments (arg1 through argn) allowed is 99 unless the option is used to allow for more output file names. If the option is specified, the resulting filenames are through prefixNN where NN is the two-digit value of n using a leading zero if n is less than 10. If the option is not specified, the default filenames through are used. file is divided as follows: Default Prefixed Filename Filename Contents ----------------------------------------------------- xx00 prefix00 From start of file up to (but not including) the line refer- enced by arg1. xx01 prefix01 From the line referenced by arg1 up to the line referenced by arg2. . . . xxNN prefixNN From the line referenced by argn to end of file. If the file argument is standard input is used. supports the Basic Regular Expression syntax (see regexp(5)). Options recognizes the following options: Suppress printing of all character counts normally prints the character counts for each file created). Leave previously created files intact normally removes created files if an error occurs). Name created files through prefixNN (default is through The output file name suffix will use number digits instead of the default This allows creation of more than 100 output files. Arguments (arg1 through argn) to can be any combination of the following: Create a file containing the section from the current line up to (but not including) the line matching the regular expression regexp. The new current line becomes the line matching regexp. Create a file containing the section from the current line up to (but not including) the nth before or after the line matching the regular expression regexp. (e.g., The new current line becomes the line matching plus or minus n lines. equivalent to except that no file is created for the section. line_number Create a file from the current line up to (but not including) line_number. The new current line becomes line_number. Repeat argument. This argument can follow any of the above argument forms. If it follows a regexp argument, that argument is applied num more times. If it follows line_number, the file is split every line_number lines for num times from that point until end-of-file is reached or num expires. Repeats previous operand as many times as necessary to finish input. Enclose in appropriate quotes all regexp arguments containing blanks or other characters meaningful to the shell. Regular expressions must not contain embedded new-lines. does not alter or remove the original file; it is the user's responsibility to remove it when appropriate. EXTERNAL INFLUENCES
Environment Variables determines the collating sequence used in evaluating regular expressions. determines the characters matched by character class expressions in regular expressions. determines the language in which messages are displayed. If or or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. DIAGNOSTICS
Messages are self explanatory except for: which means that the given argument did not reference a line between the current position and the end of the file. This warning also occurs if the file is exhausted before the repeat count is. EXAMPLES
Create four files, through After editing the ``split'' files, recombine them back into the original file, destroying its previous contents. Perform editing operations Split a file at every 100 lines, up to 10,000 lines (100 files). The option causes the created files to be retained if there are fewer than 10,000 lines (an error message is still printed). Assuming that follows the normal C coding convention of terminating routines with a at the beginning of the line, create a file containing each separate C routine (up to 21) in SEE ALSO
