sfget: Output parameters from the header.

sfget parform=y all=n par1 par2 ...

bool	all=n	[y/n]	If output all values.
bool	parform=y	[y/n]	If y, print out parameter=value. If n, print out value.

The sfget program extracts a parameter value from an RSF file. It is useful mostly for scripting. Here is, for example, a quick calculation of the maximum value on the first axis in an RSF dataset (the output of sfspike) using the standard Unix bc calculator.

bash$ ( sfspike n1=100 | sfget n1 d1 o1; echo "o1+(n1-1)*d1" ) | bc
.396
