No Child Processes - Error while running perl script
Issue
- The following error is seen when attempting to run a perl script on a system:
Error -1: echo '
error No child processes: tr "~^" " "
- Below is the code snippet of the perl script being run.
my($os_cmd) = qq(tr "~^" " " < $edi_filename > ${edi_filename}.fix);
system($os_cmd) && &my_die($!,$?,$os_cmd,"");
- However when we modify the above code snippet with a line
$SIG{CHLD} = 'DEFAULT';We do not get this error.
my($os_cmd) = qq(tr "~^" " " < $edi_filename > ${edi_filename}.fix);
$SIG{CHLD} = 'DEFAULT';
system($os_cmd) && &my_die($!,$?,$os_cmd,"");
