Hi All,
I want my file to be split based on value of 'N' (passed as argument). If value of 'N' is '2' then 4 new files will be generated from the below source file and the o/p file shoud look like File_$num , where num will be incremental.

Source file:
1
2
3
4
5

O/p Files:
File_001.txt
1
2

  File_002.txt
    3
    4

  File_003.txt
    5

Thanks in Advance,

2

==> 2.txt <==
3
4

==> 3.txt <==
5

Change val as required.

val=2
awk -v val="$val" 'BEGIN{i=1}{if(t==1){i++;t=0}}
{if($0%val==0){t=1};file="File_"i".txt";print >>file}' inputFile

if Solaris, please use nawk

When I use val=4 (i expected 4 records in File_3.txt but getting 2 records)

awk -v val="$val" 'BEGIN{i=1}{if(t==1){i++;t=0}}
{if($0%val==0){t=1};file="File_"i".txt";print >>file}' inputFile

o/p:

$ cat File_1.txt
1
2
3
4
$ cat File_2.txt
5
6
7
8
$ cat File_3.txt
9
0
$ cat File_4.txt
11
12
$ cat File_5.txt
13
14

sk1418: Contencts are getting split based on number but my files are coming with only numbers and not with f1.txt, f2.txt...

O/p file names:

4.txt
3.txt
2.txt
1.txt

Thanks
