Split a file into pieces. This generates files named "xx00", "xx01", and so on. More information: https://www.gnu.org/software/coreutils/csplit.
- 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}} /{{regex}}/
