selectively add the end of the line

Im sure this one is very easy but I can get want Im after. I have a
spice file that looks like this:

..subckt CKNXLVTD3 A ZN
M_u2 ZN A VSS VSS nch_lvt w=2.88u l=0.13u
M_u1 ZN A VDD VDD pch_lvt w=7.62u l=0.13u
D60 VSS A ndio_lvt AREA=1.65e-13 PJ=1.7e-06
..ends

and it needs to look like this:

..subckt CKNXLVTD3 A ZN VSS VDD
M_u2 ZN A VSS VSS nch_lvt w=2.88u l=0.13u
M_u1 ZN A VDD VDD pch_lvt w=7.62u l=0.13u
D60 VSS A ndio_lvt AREA=1.65e-13 PJ=1.7e-06
..ends

Basically, search for .subckt and append VSS and VDD to the line
only. The line length can be long or short

Thanks

Re: selectively add the end of the line

Yep, the both work!!!! Can you give a brief description how this
works. I was only able to print the subckt line.
What does the trailing "1" do on the awk solution?

THANKS!!!!!!

Uhm...

sed 's/^\.subckt.*/& VSS VDD/' yourfile

or

awk '/^\.subckt/ {$0=$0" VSS VDD"}1' yourfile

Is this what you want?

This says to sed: when a line is like "^\.subckt.*", ie, starts
with .subckt, then substitute that line with the whole line plus
" VSS VDD". Since the -n switch is not specified, sed prints all lines.

>> awk '/^\.subckt/ {$0=$0" VSS VDD"}1' yourfile

This is the same logic applied to awk. Awk reads the file line by line. When
a line is encountered that matches the regular expression ^\.subckt (that
is, a line that begins with .subckt), then add " VSS VDD" at the end of
that line. The "1" is an always-true condition that executes awk's default
action, which is "print the whole line" (ie, $0).
It's equivalent to:

awk '/^\.subckt/ {$0=$0" VSS VDD"}
1 {print $0}' yourfile

Note that any expression that awk evaluates as "true" could be used,
like "hello" or 345. 1 just happens to be the more commonly used choice.

True with POSIX awk,
but this one is easier and runs on old awk, too:

awk '/^\.subckt/{print $0,"VSS VDD"}' yourfile

But does this actually print the other lines?

You are right, this one returns the other lines, too:

awk '/^\.subckt/{print $0,"VSS VDD";next}{print}' yourfile
or
awk '/^\.subckt/{$0=$0"VSS VDD"}{print}' yourfile
