i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe <leah@libreboot.org>

.Sh SYNOPSIS

.Nm

|
.Op Fl dqtu
|
|
.Op Fl p Ar directory
|
|
.Op Ar template
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
creates a temporary file by generating a unique filename with
|
|
.Ar template ,
|
|
which has to have at least six 'X's appended to it.
|
|
If no
|
|
.Ar template
|
|
is specified, a default of 'tmp.XXXXXXXXXX' is used and the
|
|
tmpdir set to '/tmp' or, if set, the TMPDIR environment variable.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
Create a temporary directory instead of a file.
|
|
.It Fl p Ar directory
|
|
Use the specified
|
|
.Ar directory
|
|
as a prefix when generating the temporary filename.
|
|
The directory will be overridden by the user's
|
|
.Ev TMPDIR
|
|
environment variable if it is set.
|
|
This option implies the
|
|
.Fl t
|
|
flag (see below).
|
|
.It Fl q
|
|
Fail silently if an error occurs.
|
|
.It Fl t
|
|
Generate a path rooted in a temporary directory.
|
|
.It Fl u
|
|
Unlink file before
|
|
.Nm
|
|
exits.
|
|
This is slightly better than
|
|
.Xr mktemp 3
|
|
but still introduces a race condition.
|
|
Use of this option is not encouraged.
