The second command will not run until the first has finished.

If the first command is giving you a prompt, it is waiting for you to enter something.

If the second command is supposed to be entered at the prompt, then you need to send it to the first command as input. For example:

Code:
printf "%s\n" "rcv:menu;" exit | subshl

seesat5

seesat5(1)                                                    General Commands Manual                                                   seesat5(1)

NAME

       seesat5 - provides satellite visibility information.

SYNOPSIS

       seesat5 [ report ] [ go <Label> ] | [ <command> ... ]

DESCRIPTION

       This  program uses the sgp4 algorithm provided by NORAD to produce position information on a satellite. Seesat5 can produce tracking infor-
       mation for one satellite over a period of several days, or for a collection of satellites over that period. By providing filter  conditions
       seesat5 prints out only those satellites you might have a chance to see rather than all the satellites that pass above the horizon.

       Seesat5  is  typically  run  by placing control commands into an init file called SEESAT5.INI. See seesat5 (7) for the description of these
       commands.  If there is no init file Seesat5 will present the operator with a '>' prompt where commands can  be  entered.  From  the  prompt
       seesat5 will begin analysis when sufficient parameters have been entered to begin the run.

       Seesat5  uses  selection  conditions to filter the data so that only high and bright satellites are printed. Note that the selection condi-
       tions are used to select whether or not the current passes data will be printed. If it is printed, then the complete pass data is  printed.
       ie. all data from when the satellite comes over the horizon until it goes below.

       For lines that satisfied ALL the selection conditions, a "+" sign is printed as the first character.

   Options
       report This  option  will disable printing of report records in the output of the run. These include all command lines found in SEESAT5.INI
              or entered from the command line or the prompt.

       go     Followed by a label, this option causes branching within the SEESAT5.INI to begin execution at the line following  label.  Branching
              occurs when the cmdline command is executed in the SEESAT5.INI file.

       command
              Most of the commands that can be found in SEESAT5.INI can be entered on the command line. If you desire the SEESAT5.INI file to exe-
              cute after the command line be sure to make the last command RET.

FILES

       SEESAT5.INI
              The control file for seesat5

       *.tle  Two line element files used by seesat5.

SEE ALSO

       seesat5(7), SEESAT5.INI(5), tle(5), cr(1)

BUGS

       Seesat5 is not always able to check data integrity. Since computation and output is driven by the data in  the  two  line  element,  subtle
       errors  in  a  tle can cause floating point exceptions. In addition there are several commands that do not work well together, like SHOWTLE
       and RUNTIME. Please report any problems with seesat5 to Dale Scheetz <dwarf@polaris.net>.
