| EXIT_CODE | Description |
|---|---|
| exit(1) | It indicates abnormal termination of a program perhaps as a result a minor problem in the code. |
| exit(2) | It is similar to exit(1) but is displayed when the error occurred is a major one. This statement is rarely seen. |
| exit(127) | It indicates command not found. |
| exit(132) | It indicates that a program was aborted (received SIGILL), perhaps as a result of illegal instruction or that the binary is probably corrupt. |
| exit(133) | It indicates that a program was aborted (received SIGTRAP), perhaps as a result of dividing an integer by zero. |
| exit(134) | It indicates that a program was aborted (received SIGABRT), perhaps as a result of a failed assertion. |
| exit(136) | It indicates that a program was aborted (received SIGFPE), perhaps as a result of floating point exception or integer overflow. |
| exit(137) | It indicates that a program took up too much memory. |
| exit(138) | It indicates that a program was aborted (received SIGBUS), perhaps as a result of unaligned memory access. |
| exit(139) | It indicates Segmentation Fault which means that the program was trying to access a memory location not allocated to it. This mostly occurs while using pointers or trying to access an out-of-bounds array index. |
| exit(158/152) | It indicates that a program was aborted (received SIGXCPU), perhaps as a result of CPU time limit exceeded. |
| exit(159/153) | It indicates that a program was aborted (received SIGXFSZ), perhaps as a result of File size limit exceeded. |
