Shell Programming and Scripting

Hi, i am trying to do work on a giant text file. I want to search each line for specifictext and if it exists i want it to append specifictext2 to the end of each file. Example:
1:John went to the school today
2:Max and John are best friends
3:Joe hates them both

Search for John and append (Happy People).
Resulting in:
1:John went to the school today(Happy People)
2:Max and John are best friends(Happy People)
3:Joe hates them both

So far i have gotten as far as:
sed -e "s/.*[Jj]ohn.*/(Happy People) /g" in.txt > out.txt

But, this only inputs it to the beginning of the line. Any help is appreciated, maybe if someone is more proficient with awk? Really, what ever gets it done.

ok so now i got "sed 's/.*[Jj]ohn.*/&(Happy People)' in.txt > out.txt"

How can i edit this to search multiple strings but only replace for the first found?

Haven't had a chance to test it, but how about:

Code:

sed '/John/ {s/$/(Happy People)/;}'

Search for John or Max and append (Happy People).

Code:

sed '/[Jj]ohn\|[Mm]ax/s/$/(Happy People)/' in.txt

hey, no dice guys.

BMDan- i actually got a single search sed command working read the end part of that post.
aigles- I saw the pipe command in a manual i was reading but it didn't seem to every want to work, i put the | or even \| in there it doesnt find either.

sed '/[Jj]ohn\|[Mm]ax/s/$/(Happy People)/' $1 out.txt
sed '/.*[Jj]ohn.*\|.*[Mm]ax.*/s/$/(Happy People)/' $1 out.txt
sed '/.*[Jj]ohn\|[Mm]ax.*/s/$/(Happy People)/' $1 out.txt

sed '/[Jj]ohn|[Mm]ax/s/$/(Happy People)/' $1 out.txt
sed '/.*[Jj]ohn.*|.*[Mm]ax.*/s/$/(Happy People)' $1 out.txt
sed '/.*[Jj]ohn|[Mm]ax.*/s/$/(Happy People)/' $1 out.txt

none of these seem to do the trick. i found this:
# change "scarlet" or "ruby" or "puce" to "red"
sed 's/scarlet/red/g;s/ruby/red/g;s/puce/red/g' # most seds
gsed 's/scarlet\|ruby\|puce/red/g' # GNU sed only

i believe my best bet may be to find a gnu sed? the other command doesnt work either. I am running a version picked from aptitude so i believe it should be a correct version.

Did you declare $1 ? and where is the redirect (>).

if you have a huge file, use sed is slower (since it goes through substitution) than just grepping for the pattern and printing them out.

Code:

awk '/[Jj]ohn|[Mm]ax/ {print $0"(Happy People)";next }1 ' file

THANKS GUYS!

ghostdog74: perfect this command works excellently! thanks a bunch!

danmero: deerrrrr, yes i declared $1 on the command line and redirect is to out.txt. Thanks for the effort

thanks everyone who helped it is greatly appreciated.
