看这里，有tar的返回值文档
http://www.gnu.org/software/tar/manual/html_section/Synopsis.html

Possible exit codes of GNU tar are summarized in the following table:

0
‘Successful termination’.

1
‘Some files differ’. If tar was invoked with ‘--compare’ (‘--diff’, ‘-d’) command line option, this means that some files in the archive differ from their disk counterparts (see section Comparing Archive Members with the File System). If tar was given ‘--create’, ‘--append’ or ‘--update’ option, this exit code means that some files were changed while being archived and so the resulting archive does not contain the exact copy of the file set.

2
‘Fatal error’. This means that some fatal, unrecoverable error occurred.
