split command and putting output to the specific pattern files

when we use following command:

split -l  1000 test.txt

the result would be xaa xab xac ...

how can I put the out put to pattern made by me? for example: I want to do:

split -l 1000 test.txt

and the result should be:

0001 0002 0003 0004 ... 10000 10001...

I want to use numbers instead of xaa etc... thank you in advance.

Find the man page for split and with GNU split (but not others, such as BSD split as found on Mac OS X), you can use:

-d 100

to specify numeric suffixes starting at 100 (for example; or you can omit the number to start at 1), and:

-a 4

to specify that the suffixes should be (at least) 4 digits, and you can specify the prefix after the file name:

split -l 1000 -d 100 -a 4 test.txt prefix.

So, for your example, you could simply write:

split -d -a 4 test.txt ''

(since the default split is 1000 lines, which you specified explicitly as -l 1000).
