What is meaning of exit status 1 returned by linux command? Like 127 exit status indicates "command not found".
I have visited http://linux.die.net/abs-guide/exitcodes.html page, does it mean exit status 1 does not have particular special meaning?

1The ABS link is confused. These exit codes are not "reserved" and the table is a happy drunk mixture of Bash-internal usage, general Unix conventions, and the author's loud opinion. – tripleee Jan 07 '14 at 07:45

The only general convention is that a zero exit status signifies success, whereas any non-zero exit status is a failure.
Many -- but certainly not all -- command-line tools return exit code 1 for syntax error, i.e. you had too few arguments or an invalid option.
Many -- but, alas, not all -- command-line tools have a manual page. By convention, it should document the exit codes of the program, but many do not.

You can see the value of the exit status using man.
Giving an example below:
man ls
Now search for string exit

As tripleee posted not all command's man page documented exit codes. I am facing exit status related problem for command msgfmt, it's man page does not documented about exit codes. – user2664054 Jan 07 '14 at 11:11

[msgfmt.c](http://git.savannah.gnu.org/cgit/gettext.git/tree/gettext-tools/src/msgfmt.c) seems to use the generic [EXIT_FAILURE](https://www.gnu.org/software/libc/manual/html_node/Exit-Status.html) in basically every error situation. There would be an error message telling you what went wrong, though. – tripleee Nov 01 '15 at 09:51

Exit Code 1 means that a container terminated, typically due to an application error or an invalid reference. A non-zero (1-255) exit status indicates failure.
For example, if a Java library is running , and the library throws a compiler error, the container might terminate with Exit Code 1.
A command which exits with a zero (0) exit status means it succeeded.
