Shell Programming and Scripting

Replace these lines:

Code:

system("cal ..." >out.txt");
while(getline < "out.txt")
{OPFILE=$0;}

with:

Code:

while("cal ..."| getline OPFILE) {..}

Franklin:
I tried following possiblities


while(("cal "month" "year" | tail -7|tr \" \" \";\"|tr \"\\n\" \";\" | getline OPFILE"))
{
print "Here...."OPFILE
}

while(("cal "month" "year" | tail -7|tr \" \" \";\"|tr \"\\n\" \";\"" | getline OPFILE))
{
print "Here...."OPFILE
}


while(system("cal "month" "year" | tail -7|tr \" \" \";\"|tr \"\\n\" \";\"" | getline OPFILE))
{
print "Here...."OPFILE
}

while(system("cal "month" "year" | tail -7|tr \" \" \";\"|tr \"\\n\" \";\" | getline OPFILE"))
{
print "Here...."OPFILE
}


But none worked...
