General Form:

version [-s | -f | <version id>]

Print out the version of ngnutmeg that is running, if invoked without argument or with -s or -f. If the argument is a <version id> (any string different from -s or -f is considered a <version id> ), the command checks to make sure that the arguments match the current version of ngspice. (This is mainly used as a Command: line in rawfiles.)

Options description:

• No option: The output of the command is the message you can see when running ngspice from the command line, no more no less.
• -s(hort): A shorter version of the message you see when calling ngspice from the command line.
• -f(ull): You may want to use this option if you want to know what extensions are included into the simulator and what compilation switches are active. A list of compilation options and included extensions is appended to the normal (not short) message. May be useful when sending bug reports.

The following example shows what the command returns in some situations:

Use of the version command:

ngspice 10 -> version

ngspice 2 -> 
ngspice 11 -> version 14 
Note: rawfile is version 14 (current version is 24)
ngspice 12 -> version 24
ngspice 13 -> 

Note for developers: The option listing returned when version is called with the -f flag is built at compile time using #ifdef blocks. When new compile switches are added, if you want them to appear on the list, you have to modify the code in misccoms.c.
