From: rickm on 17 Apr 2008 10:59 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

The line length can be long or short Uhm... sed 's/^\.subckt.*/& VSS VDD/' yourfile or awk '/^\.subckt/ {$0=$0" VSS VDD"}1' yourfile Is this what you want? -- D.
From: rickm on 17 Apr 2008 11:17 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!!!!!!

I was only able to print the subckt line. > What does the trailing "1" do on the awk solution? > >> sed 's/^\.subckt.*/& VSS VDD/' yourfile 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. -- D.
