I wrote a Perl script to have the BSD flavor install on our System V machines.
We have a mixture of machines, and I didn't want to have two different
Makefiles or targets to install every program. Enjoy!

XThis "install" program is a perl script. You need Larry Wall's perl v3 to run
Xit. You can get the latest version of perl via anonymous FTP from
Xjpl-devvax.jpl.nasa.gov (128.149.8.43). I highly recommend it.
X
XI wrote "install" because even though our System V hosts have an "install"
Xcommand, it has completely different options. I wanted just one version of
XMakefiles for all of our machines and since I was familiar with the bsd version
Xof "install", I wrote a script to emulate it. It also works equally as well on
Xour System V and BSD 4.[23] machines, and supports every option BSD does.
X
XI've also added a couple of options and features.
X
XThe two additional command line options are "-r" to remove the target before
Xinstalling the new one, and "-l" to do an "ll" after the installation is
Xcomplete. These are two changes to Makefiles I found myself making
Xconstantly.
X
XThe "-l" option of install requires that you have a "ll" command on every
Xsystem. On BSD systems that didn't come with an "ll" command, I installed the
Xenclosed two line "ll" Bourne shell script in "/bin". On our System V hosts, I
Xinstalled the same script, but edited out the -g option (so the output looks
Xthe same).
X
XI also added the ability to install files on multiple hosts with one command.
XYou do this by specifying the target as "hostlist:target", where the "hostlist"
Xis a list of hosts, separated with a plus sign. "rsh" and "rcp" commands are
Xused to perform the remote operations, but since rsh doesn't return the remote
Xcommand's status, you can't really be sure each remote command is working
Xokay.
X
XIn my Makefiles, I define the variable "HOST" to be a list of hosts or their
Xnicknames that I want the files installed. This works well because I can
Xoverride the default hostlist by specifying an overriding "HOST=someotherhost"
Xon the "make" command line when I want to. See the "Makefile" in this
Xdirectory for an example.

X
X.SH NAME
Xinstall \- install a program or file
X
X.SH SYNOPSIS
X.B install
X[\-c] [\-g group] [\-l[ls-options]]
X[\-m mode] [\-o owner] [\-r] [\-s]
Xsource-file [host[+host...]:]target [target ...]
X
X.SH DESCRIPTION
X.I Install
Xperforms operations that are commonly done when installing a program
Xor other file in some system directory.
X
XYou must specify one source file, and at least one target file or
Xdirectory name. If the target specified is a directory, a file
Xby the same name as the source file will be installed inside in that
Xdirectory.
X
XYou may optionally specify as targets, multiple files, remote files (in the
Xformat host:file), multiple remote files (in the format host+host:file), or a
Xmixture of any of these. This finally makes installing a file on multiple
Xsystems very easy.
X
XThe options you specify control what is done to the source and target files.
XWith no options, the source file is simply moved to the target file.
X
X.I Install
Xwill stop if any errors occur,
Xbut when executing commands using the remote shell command (rsh),
Xno status code is returned from the remote command, so install
Xcannot tell if the remote command was successful, and will always
Xcontinue as if it was.
X
X.SH OPTIONS
X\-c indicates that the source file is to be copied, not moved, to the
Xtarget file. In other words, the source file should not be deleted after
Xthe installation is completed.
X
X\-g specifies the group name or number that should be assigned to the target file(s).
XYou must be the superuser, or the owner of the file and a member of the
Xgroup to change the group assigned to a file.
X
X\-l indicates that an "ls" should be performed on the target file
Xafter the installation is done. This is useful for verifying that the
Xinstallation worked correctly. You may optionally specify the options to
Xpass to the "ls" command. The default options used are "\-Fgl".
X
X\-m specifies the mode that should be assigned to the target file(s).
XYou must be the superuser, or the owner of the file
Xto change the mode assigned to a file.
X
X\-o specifies the login name or number that should own the target file(s).
XOn BSD systems, only the superuser can change the owner of a file. On
XSystem V systems, only the superuser or the owner of a file can change
Xit's owner.
X
X\-r indicates that any old target file should be removed before the new
Xfile is installed. This is useful for preventing problems caused by
Xownership, group, or permissions of an old version of the target file.
X
X\-s indicates that the target file should be stripped of symbols. Only
Xuse this option on executable images.
X
X\-v indicates that the install program should be verbose, and display every
Xcommand before it is executed.
