regex - Looking for correct Regular Expression for csplit -

i have file contains several lines these:

1291126929200 started 88 videolist15.txt 4 4 1291126929250 59.875 29.0 29.580243595150186 43.016096916037604 1291126929296 59.921 29.0 29.52749417740926 42.78632483544682 1291126929359 59.984 29.0 29.479540161281143 42.56031951027556 1291126929437 60.046 50.0 31.345036510255586 42.682281485516945 1291126932859 started 88 videolist15.txt 5 4 

i want split files every line contains started (or videolist, not matter).

the following command produces 2 output files:

$ csplit -k input.txt /started/ 

however expect lot more, can seen in:

$ grep -i started input.txt |wc -l $ 146 

what correct csplit command?

thanks

just add {*} @ end:

$ csplit -k input.txt /started/ {*} 

the man page says:

{*}    repeat previous pattern many times possible. 

demo:

$ cat file 1 foo 2 foo 3 foo $ csplit -k file /foo/ {*} 2 6 6 4 $ ls -tr xx*              xx03  xx02  xx01  xx00 $ csplit --version csplit (gnu coreutils) 7.4
