I'd like to call the first command listed in a simple text file with \n as the separator in a pop-like fashion:
Figure 1:
cmdqueue.lst :
proc_C1
proc_C2
proc_C3
.
.
Figure 2:
Pop the first command via popcmd:
proc_A | proc_B | popcmd cmdqueue.lst | proc_D
Figure 3:
cmdqueue.lst :
proc_C2
proc_C3
proc_C4
.
.
