In other words, the system doesn't understand your command, because it doesn't know where to find the binary you're trying to call. share|improve this answer edited Jan 2 '13 at 8:34 answered Nov 19 '09 at 13:08 Oldskool 19.1k63156 11 This also happens if a bash script does not have mode "+x" but does indeed exist. –MatthewKremer Mar 4 '14 at 20:48 You can try using which [program] to see which binary the OS is using. If it comes up empty, next step is checking execution bit and PATH. –cr125rider Jun 12 '14 at 16:33 5 @cr125rider, which is not particularly accurate -- it doesn't know about aliases, shell functions, PATH lookup memoization, or other factors internal to shell state. Much better to use type, a shell builtin which knows about all of those things. –Charles Duffy Sep 11 '14 at 22:45 I didn't know about type, thanks –cr125rider Sep 15 '14 at 20:13 This also happened to me with a file that had Windows line feeds. Correcting the line endings to unix format solved the problem –Mitkins Sep

But I am getting return codes as 0,127 randomly On checking the return codes for wait, I found the below. Do I need to treat return code of 127 as successful as well?? error code 127 as we know the process id passed is correct. Is terminated different than successful? I am getting the return codes randomly. Code: 0 Successful completion. 1-126 An error occurred. 127 A specified pid or job-id has terminated or is unknown by the invoking shell.

Kshell behaves the same way. I would treat any non-zero return from wait as a failure. Remove advertis
