Shell Programming and Scripting

Hi,

I need your help on the following Scenario :

Consider a file has 650 records and I need to split this file into 4 files having a maximum of 200 records in each of them and also for the first splitted file it should get appended with Page 1 as a trailer( Similarly for the second file, Page 2 should be the Trailer..For Third it should be Page 3 and so on..).

How can we do this ??

Hi

Code:

$ cat file
1
2
3
4
5
6
7
8
9
10

Code:

$ awk '{print > "FILE"x;}!(NR%4){print "PAGE "x > "FILE"x;x++;}END{print "PAGE "x > "FILE"x}' x=1 file

Code:

$ cat FILE1
1
2
3
4
PAGE 1
$ cat FILE2
5
6
7
8
PAGE 2
$ cat FILE3
9
10
PAGE 3

Replace 4 with 200 in your case.

Hi Guru,

Can u explain this code a bit ?

Hi

Code:

{print > "FILE"x;}

-> Write every record to the file "FILE"x where x is 1,2,3 and so on. x starts with 1 and gets incremented for every 4 records.

Code:

!(NR%4){print "PAGE "x > "FILE"x;x++;}

-> When a line which is a multiple of 4(4,8,12..) is reached, write the trailer record and increment x.

Code:

END{print "PAGE "x > "FILE"x}

-> For the last file, write the trailer record.
