How to split files with numeric names?

Question

I'm trying to split text file into files of 1024 lines, so I ran split with the -d switch:

split -d -l 300 ./list.lst

I get some weird names: they start with x and the file names jump from x89 to x9000. I want the files to be named like that:

1.lst
2.lst
3.lst
...

Thanks.

Solution

At least with the GNU Coreutils version of split, you can do it as follows:

split -l300 --numeric-suffixes=1 --suffix-length=1 --additional-suffix=".lst"  file ""

Note the use of "" to specify an empty prefix (the xa part of the default filename) and the use of --numeric-suffixes in place of -d (which always starts from 0).

Note also that this assumes that the file to be split contains no more than 9 x 300 lines - otherwise split will complain that output file suffixes exhausted

Ex.

$ split -l300 --numeric-suffixes=1 --suffix-length=1 --additional-suffix=".lst" --verbose file ""
creating file '1.lst'
creating file '2.lst'
creating file '3.lst'
creating file '4.lst'

With --suffix-length=1 it is only possible to create 9 parts (1-9). The user is creating more than 89 parts (because he reports filenames as x9000). So, length should be at least 3 (or more).
