Add a line with sed

Hello,
I know this post is old, but for those still looking for a solution, here is what I propose.

To insert(i), add(a), or exchange(c) a line with the sed command

ex: add to the end of the file
sed -e '$a\text you want ' file

ex: add after the line "add this text after line "2"
sed -e '2a\text you want ' file

Using the (i) option, your text is positioned on line 2 and shifts the rest of the text.

I hope this helps someone

Hello!
I just found this, I hope you find the answer in there ^^!
Have a good day

Thank you for your reply, but the provided solution does not work on my server,
sed '4i\ toto' -> sed: command garbled: 4i\ toto

I read the tutorial on the site, but the examples are not very clear to me.

Thank you.

toto is an example, isn't it?

Yes, toto, it's good for an example, I still have the problem sed: command garbled
I am on Solaris 9.

Thank you.

num=4; sed "$num a\ But I feel it's coming " file.txt

Always the same error message,

I tried with i but the same, maybe I should use an awk?

Thank you

Hello,

or with perl ;-) (I haven't tested it)

perl -pi.orig -e 'print "But I feel that it's coming\n" if $. == 3"' file.txt

So I don't know Perl, but I tried and it gave me:

String found where operator expected at -e line 1, at end of line
(Missing semicolon on previous line?)
Can't find string terminator '"' anywhere before EOF at -e line 1.

Thank you

Oups, I added an extra quote ;-)

perl -pi.orig -e 'print "But I feel like it's coming\n" if $. == 3' file.txt

Ça marche mais c'est pas stable, je m'explique quand je le lance telle que tu me la donner ca marche cependant quand je l'adapte a mon script en rajouter des variables il fait des doublons dans mon fichiers notamment pour écrire a la dernière ligne.

mon utilisation : variable remplacer.

perl -pi.tmp -e 'print "toto\n" if $. == 11' fichier.txt

fichier.txt

Mais je sens que ça va venir -> test via la commande non adapter

Merci

Could someone have another idea or syntax for sed?

Thank you

num=4; sed "$num s/.*/&\nBut I feel like it's coming/" file.txt

I think we're not far off, the command works but doesn't insert a line break:

num=4; sed "$num s/.*/&\n But I feel like it's coming/" file.txt

# Configuration file containing the company's non-working days (Pentecost,
# public holidays), the dates are in DD/MM/YYYY format.
14/07/2006
17/07/2006n But I feel like it's coming
18/07/2006
15/08/2006

if we could insert a line break it would be perfect.

Thank you

Rajoute un "anti-slash" :

sed "$num s/.*/&\\\n Mais je sens que ça va venir/"

Hello,

I tried everything but it doesn't break the line, I also tried the '' "" with no success.

Thank you

Hello,

too bad I settled for redirecting the text into my file, so I'm doing an insertion at the end of the file,

echo $text >> $mon_fichier

thank you all.

It helped me, thank you!
