.Sh NAME
|
|
.Nm atf-sh
|
|
.Op Fl s Ar shell
|
|
.Nd interpreter for shell-based test programs
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar script
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is an interpreter that runs the test program given in
|
|
.Ar script
|
|
after loading the
|
|
.Xr atf-sh 3
|
|
library.
|
|
.Pp
|
|
.Nm
|
|
is not a real interpreter though: it is just a wrapper around
|
|
the system-wide shell defined by
|
|
.Va ATF_SHELL .
|
|
.Nm
|
|
executes the interpreter, loads the
|
|
.Xr atf-sh 3
|
|
library and then runs the script.
|
|
You must consider
|
|
.Nm atf-sh
|
|
to be a POSIX shell by default and thus should not use any non-standard
|
|
extensions.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width XsXshellXXX
|
|
.It Fl s Ar shell
|
|
Specifies the shell to use instead of the value provided by
|
|
.Va ATF_SHELL .
|
|
.El
|
|
.Sh ENVIRONMENT
|
|
.Bl -tag -width ATFXLIBEXECDIRXX -compact
|
|
.It Va ATF_LIBEXECDIR
|
|
Overrides the builtin directory where
|
|
.Nm
|
|
is located.
|
|
Should not be overridden other than for testing purposes.
|
|
.It Va ATF_PKGDATADIR
|
|
Overrides the builtin directory where
|
|
.Pa libatf-sh.subr
|
|
is located.
|
|
Should not be overridden other than for testing purposes.
|
|
.It Va ATF_SHELL
|
|
Path to the system shell to be used in the generated scripts.
|
|
Scripts must not rely on this variable being set to select a specific
|
|
interpreter.
|
|
.El
|
|
.Sh EXAMPLES
|
|
Scripts using
|
|
.Xr atf-sh 3
|
|
should start with:
|
|
.Bd -literal -offset indent
|
|
#! /usr/bin/env atf-sh
|
|
.Ed
|
|
.Pp
|
|
Alternatively, if you want to explicitly choose a shell interpreter, you cannot
|
|
rely on
|
|
.Xr env 1
|
|
to find
|
|
.Nm .
|
|
Instead, you have to hardcode the path to
|
|
.Nm
|
|
in the script and then use the
|
|
.Fl s
|
|
option afterwards as a
|
|
.Em single parameter :
|
|
.Bd -literal -offset indent
|
|
#! /path/to/bin/atf-sh -s/bin/bash
|
|
.Ed
|
|
.Sh ENVIRONMENT
|
|
.Bl -tag -width ATFXSHELLXX -compact
|
|
.It Va ATF_SHELL
|
|
Path to the system shell to be used in the generated scripts.
