PROLOG<\/a> This manual page is part of the POSIX Programmer\u2019s Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.<\/p>\n return \u2014 return from a function or dot script<\/p>\n return [<\/b>n<\/i>]<\/b><\/p>\n The return<\/i> utility shall cause the shell to stop executing the current function or dot<\/i> script. If the shell is not currently executing a function or dot<\/i> script, the results are unspecified.<\/p>\n None.<\/p>\n See the DESCRIPTION.<\/p>\n Not used.<\/p>\n None.<\/p>\n None.<\/p>\n Default.<\/p>\n Not used.<\/p>\n The standard error shall be used only for diagnostic messages.<\/p>\n None.<\/p>\n None.<\/p>\n The value of the special parameter \u2019?\u2019<\/b> shall be set to n<\/i>, an unsigned decimal integer, or to the exit status of the last command executed if n<\/i> is not specified. If n<\/i> is not an unsigned decimal integer, or is greater than 255, the results are unspecified. When return<\/i> is executed in a trap<\/i> action, the last command is considered to be the command that executed immediately preceding the trap<\/i> action.<\/p>\n Default.<\/p>\n The following sections are informative.<\/i><\/p>\n None.<\/p>\n None.<\/p>\n The behavior of return<\/i> when not in a function or dot<\/i> script differs between the System V shell and the KornShell. In the System V shell this is an error, whereas in the KornShell, the effect is the same as exit<\/i>.<\/p>\n The results of returning a number greater than 255 are undefined because of differing practices in the various historical implementations. Some shells AND out all but the low-order 8 bits; others allow larger values, but not of unlimited size.<\/p>\n See the discussion of appropriate exit status values under exit<\/i>.<\/p>\n None.<\/p>\n
