Hi all,

I am confused about When and where to use exit 0 and exit 1 ...

Thanks

those are indicators to the external environment abt the status of execution of the program ( child's indication to parent )

you could map any of the return codes to {0, 1} to either SUCCESS or FAILURE

but convention is,
0->SUCCESS
1->FAILURE

exit 0 : normal exit (Program Success)
exit 1 : forced Exit (Program contains error and has to be terminated)
