Shell Programming and Scripting

Hey friends,
Here I am with another query. I have a TXT file.
Foe an example

EX ID : B-Mezine
....
...
...
Some lines of text (Not fixed in length n no of lines)..
...
...
..
END EX ID

Some blank lines in between two records(Not fixed in numbers)

EX ID : B-Mezine
....
...
...
Some lines of text (Not fixed in length n no of lines)
..
...
...
..END EX ID
Some blank lines in between two records(Not fixed in numbers)
EX ID : B-Mezine
....
...
...
Some lines of text (Not fixed in length n no of lines)
..
...
...
..END EX ID


Now if I consider portion from EX ID : B-Mezine to END EX ID a record then this file has some thousand record in it.

Now what I want is, I want to split this file in say 7700 records in each file. For eg. If a file has 38700 records and I want to split this file in 7700-7700 records then it should copy first 7700 records from the main file n paste it in a new file named as part1.txt, den next 7700 records-part2.txt n so on.

Can any one help me in this matter?

Thanx in advance

In your example, you show many lines but three records. So, are you saying that the file hase 38500 records configured as your examples, and you want to make five 7700 record files from this?

dear Joeyg,
Input file 38700 regords in the format which i hv illustrated (my format shows 3 records, but in actual input file there are 38700 records which I want to split in 1-7700 records in 1st file (o/p File name part1.txt), 7701-15400 in 2nd file (o/p File name part2.txt), 15401-23100 in 3rd file (o/p File name part3.txt) and so on.

Try this:

Code:

awk 'NR%7700==1 {i++} {print > "part"i".txt"}' file

Regards

Thanx for the solution buddy,
But it is splitting the file on the basis of number of lines i.e. 7700 lines in each o/p file, which is not i am looking for. I have an input file which has around 35,500 number of records which starts by the pattern "EX ID : B-Mezine" and consists some data which is not fixed in lenght n number of lines, and after that it ends with pattern "END EX ID" and this is called as "A Record"

The script ideally should pick 7700 records from input file, write it to out put file named as part1.txt, then next 7700 records, writes it to o/p fil named as part2.txt nso on.

Waiting for your reply anxiously
Please...
