I need to replace a place holder in a file with the contents of an external file like so:

1st file:

2nd file:

result:


The best i have come up with so far is this:

I want to keep the formatting in both files in the final result, been googling and can't find an obvious solution, I would prefer sed but that 's not set in stone.
Any takers?

hi,

Works perfectly just what I was looking for but why the newline and d and the curly braces? This does the same:
Thanks !

Never mind just looked at the output from the two different lines and realized that your version removes the place holder as well

I find watael's solution simpler - on one line :

or, parameterized :

sed(1) is meant to modify a stream, and ed(1) to edit a file, so the
latter appears to be the more suitable solution for the said purpose.

the 'sed' solution is a bit faster than the 'ed' solution - which of both appears to be more suitable for us poor mortals ?

Well, their execution time is quite similar, but the main factor that differentiates them
is the fact that sed(1) uses a temporary file while ed(1) does not. (It's an editor!)


Doing this (using the -i switch to edit the file in place):

is theorically like doing:

yes, yes, jsz, for purity's sake you're right
