Something like this ?
awk -v file2insert=file2 -v insertafter=3 '
{print}
NR==insertafter{while((getline<file2insert)>0)print}
' /path/to/file1

Hope This Help, PH.

awk -v file2insert=file2 -v insertafter=3 '
Launch awk with 2 variables initialised from the shell:
file2insert will be an awk variable containing the pathname of the file to merge
insertafter will be an awk variable containing the line number after which the merge must be done
{print}
print to the output file each line of the input file
NR==insertafter
If we have just read (and printed) the number of desired lines
{while((getline<file2insert)>0)print}
Loop reading each line of the desired file and printing them
' /path/to/file1
name of input file
Anyway: man awk

It is simpler to use sed :
[tt]
sed '3r file2' file1
[tt]

Salut Jean-Pierre.
I agree, but we are in the AWK forum, aren't we ?
