UNIX for Dummies Questions & Answers

Hi,


I have one large files of 100000 rows with header column.

Eg:

Code:

Emp Code, Emp Name
101,xxx
102,YYY
103,zzz
...
...

I want to split the files into smaller files with only 30000 rows each..File 1,2 and 3 must have 30000 rows and file 4 must contain 10000 rows.

But the column header must available in all the smaller files(i.e) Emp Code and Emp Name in all the files in first row.

Is there any option in Split command or we have to use awk command?

Please help?

There is no option in standard split to preserve the header.
You could try a simple awk instead:

Code:

awk -v n=30000 'NR==1{h=$0; next} ++c==n || fn==0 {close(f); f=FILENAME "." ++fn; c=0; print h>f} {print>f}' file
