sfput: Input parameters into a header.

sfput < in.rsf > out.rsf

sfput is a very simple program. It simply appends parameters from the command line to the output RSF file. One can achieve similar results with editing by hand or with standard Unix utilities like sed and echo. sfput is sometimes more convenient because it handles input/output operations similarly to other regular RSF programs.

bash$ sfspike n1=10 > spike.rsf
bash$ sfin spike.rsf
spike.rsf:
    in="/tmp/spike.rsf@"
    esize=4 type=float form=native
    n1=10          d1=0.004       o1=0          label1="Time" unit1="s"
        10 elements 40 bytes
bash$ sfput < spike.rsf d1=25 label1=Depth unit1=m > spike2.rsf
bash$ sfin spike2.rsf
spike2.rsf:
    in="/tmp/spike2.rsf@"
    esize=4 type=float form=native
    n1=10          d1=25          o1=0          label1="Depth" unit1="m"
        10 elements 40 bytes
