RE: How to check if the job is failure or successful in sub1 befo re calling sub2

[Tim Johnson]

 
Usually you do this by returning a 0 if the sub fails or any other value if
it is successful.  

Simple Example:

if(lookforfolder()){
   print "It's there!\n";
}else{
   print "Folder not found\n";
}

sub lookforfolder{
   if(-d "/home/me"){
      return 1;
   }else{
      return 0;
}

Hello all,

Can somebody throw some light on this.

1. How to capture errors from the output running a
perl script. 
2. How to check if the job is failure or successful in
sub1 before calling sub2. 


Thanks
