hi all,
i have problem with my script in unix ...i have script with split -d (--numeric-suffixes) in linux its working but in solaris machine the option -d isn't have

so how to i can change split -d (this output) will same in output solaris can i change with awk and how do that

thx before

if you give sample file and the expected output format, then we can easily tell the alternative solution in awk

thx before @itkamaraj for respone my question ok this likesample

i have big file ex:201012.txt with 4000000 line number in linux i always using this syntax

split -a 4 -l 1000000 -d 201012.txt 201012

so output will like this

2010120000
2010120001
2010120002
2010120003
