add a new line on top of a file
infile
Code:
a b c
A E F
1 2 3

outfile
Code:
new line
a b c
A E F
1 2 3

I tried:

Code:
sed '1i\
new line' infile > outfile

cat outfile
Code:
new linea b c
A E F
1 2 3

I don't want the new line be added to the existing first line.
Thanks
Joseph

Code:
awk 'BEGIN{print "new line"}{print}' infile > outfile

or a non-elegant but effective method.
Code:
echo "new line" >foo
cat foo infile >outfile

awk works fine
Code:
$awk 'BEGIN{print "new line"}{print}' infile > outfile
$cat outfile
new line
a b c
A E F
1 2 3

but the other dosen't look right

Code:
$ echo "new line" >foo
$ cat foo infile >outfile
$ cat outfile
new line
a b c
A E F
1 2 3 $

Hi frank_rizzo

I have a follow up question.
my new line must include ' ' or " " as follows:
Code:
name=test color='255,0,0 0,0,255'

or
Code:
name=test color="255,0,0 0,0,255"

infile:
Code:
a b c
A E F
1 2 3

outfile should look like this
Code:
name=test color='255 0 00 0 255'
a b c
A E F
1 2 3


or like this:
Code:
name=test color="255,0,0 0,0,255"
a b c
A E F
1 2 3

here is what I got when I used ' '

Code:
awk 'BEGIN{print "name=test color='255,0,0 0,0,255'"}{print}' infile 
awk: non-terminated string name=test ... at source line 1
 context is
	 >>>  <<< 
awk: giving up
 source line number 2

when I use " "

Code:
awk 'BEGIN{print "name=test color="255,0,0 0,0,255""}{print}' infile 
name=test color=255 0 00 0 255
a b c
A E F
1 2 3

thanks

what about if add another term to my new line;
my new line looks like tihs:
Code:
name=test color="255,0,0 0,0,255" priority=10

Code:
awk 'BEGIN{print "name=test color=\"255,0,0 0,0,255\"" priority=10}{print}' infile
awk: syntax error at source line 1
 context is
    BEGIN{print "name=test color=\"255,0,0 0,0,255\"" >>>  priority= <<< 10}{print}
awk: illegal statement at source line 1
