Yet another Sed question....
How do I inject the lines from one text file into another file at a specific line number?

Ive seen a few solutions on the net, none of which have worked. Smilie

Cheers

Sample example....

Code:
$ cat file1
line 1
line 2
line 3
line 4
 
$ cat file2
123
456
 
$ sed '2 r file2' file1
line 1
line 2
123 
456
line 3
line 4

The above code will insert all the lines from file2 to file1 after 2nd line....

Post a sample input and output using code tags if you are not convinced....

Data
A code snippet:

Code:
....

echo "" > $TMP_OUT
 	echo "LABEL $HOST $BUILD" >> $TMP_OUT
 	echo  "MENU LABEL $HOST $BUILD" >> $TMP_OUT
 	echo  "KERNEL  vmlinuz-$BUILD" >> $TMP_OUT
 	echo  "APPEND initrd=initrd-$BUILD.img method=$SERVER/$BUILD ksdevice=eth0  ksfile=$SERVER/files/$KSFILE noipv6" >> $TMP_OUT

	sed '2 r $TMP_OUT' temp.menu 

....

As you can see, I am trying to insert the contents of $TMP_OUT into temp.menu. $TMP_OUT is created perfectly each time. temp.menu is not.

Ive tried something like:

Code:
sed '2 r $TMP_OUT' temp.menu  > temp1.menu

Again, didnt work. Smilie

Cheers
Simon

I m getting the correct answer

see my below code..

Code:
$ cat file1
1 2 3 4 abcded
2 4 5 1 bcdef
5 1 2 3 enfjslj
2 3 1 5 fasfjdls


Code:
$ cat file2
BAW
BRITISH AIRWAYS
RYR
RYAN AIR

Code:
TMP_OUT=`echo "file1"`


OUTPUT:
Code:
$ sed "2 r $TMP_OUT" file2
BAW
BRITISH AIRWAYS
1 2 3 4 abcded
2 4 5 1 bcdef
5 1 2 3 enfjslj
2 3 1 5 fasfjdls
RYR
RYAN AIR

Hope this makes sence...

Thanks
SHa
