installbsd(1)						      General Commands Manual						     installbsd(1)

NAME

       installbsd - Installs a command (BSD version)

SYNOPSIS

       installbsd [-cs] [-g group] [-m mode] [-o owner] file destination

       The installbsd command moves or copies a binary file to the specified destination file or directory.  It is most often used in makefiles.

OPTIONS

       Copies  file to destination rather than moving it.  Specifies a group for the destination file.	The default group is staff.  Specifies the
       mode of the destination file.  The default mode is 755.	Specifies the owner of the destination file.  The default owner is  root.   Causes
       the binary file to be stripped after installation (see strip(1)).

DESCRIPTION

       If  destination is a file and such a file already exists, installbsd removes it before file is moved or copied.	If destination is a direc-
       tory, file is moved or copied into that directory with its original filename.  installbsd will not move a file onto itself.

EXAMPLES

       To install a new command called fixit, enter: installbsd -c -o henry fixit /usr/bin

       This installs a new command by copying the program fixit to /usr/bin/fixit, with user henry as owner.

SEE ALSO

       Commands:  chgrp(1), chmod(1), chown(1), cp(1), install(1), make(1), mv(1), strip(1)
