csplit

Split a file into pieces.

This generates files named "xx00", "xx01", and so on.

• Split a file at lines 5 and 23:

csplit {file} {5} {23}

• Split a file every 5 lines (this will fail if the total number of lines is not divisible by 5):

csplit {file} {5} {*}

• Split a file every 5 lines, ignoring exact-division error:

csplit -k {file} {5} {*}

• Split a file at line 5 and use a custom prefix for the output files:

csplit {file} {5} -f {prefix}

• Split a file at a line matching a regular expression:

csplit {file} /{regular_expression}/
