csp_helper(1)							  USER COMMANDS 						     csp_helper(1)

  NAME
      csp_helper - A collection of caspar helper scripts

  SYNOPSIS
      csp_install dir (directory) file (file)

      csp_mkdircp dir (directory) file (file)

      csp_scp_keep_mode h ([user@]host) dir (directory) file (file)

      csp_sucp h ([user@]host) dir (directory) file (file)

  DESCRIPTION
      The  scripts  csp_install,  csp_mkdircp,	csp_scp_keep_mode  and csp_sucp are helpers for caspar(7). These scripts typically are not invoked
      directly, but via a Makefile which uses caspar. See the notes on	csp_PUSH  in  caspar(7)  for  information  on  how  to	link  csp_install,
      csp_scp_keep_mode and csp_sucp to caspar.

  install DESCRIPTION
      csp_install creates the required directory (if needed) and installs the file, preserving timestamps. It uses install(1).

  install EXAMPLES
       csp_INSTALL_OPTIONS='--owner=www-data --group=www-data' 
	csp_INSTALL_MODE=ugo=r 
	csp_install /srv/www index.html

       csp_INSTALL_MODE=u=rwx,go= csp_install /usr/local/sbin mkpasswd

  install ENVIRONMENT
      csp_install honors csp_INSTALL_OPTIONS and csp_INSTALL_MODE (default is u=rw,go=r).

  mkdircp DESCRIPTION
      csp_mkdircp calls mkdir(1) and cp(1).

  scp_keep_mode DESCRIPTION
      csp_scp_keep_mode  uses  ssh to copy a file to a remote host, keeping its file permission mode. The trick used is a combination of mktemp(1)
      and mv(1).  Useful if you'd like to be sure a file gets installed e.g. group writable, without fiddling with permission bits on  the  remote
      host.

  scp_keep_mode EXAMPLE
	chmod g+w rc
	csp_scp_keep_mode root@gandalf /etc/uruk rc

  scp_keep_mode ENVIRONMENT
      csp_scp_keep_mode honors csp_SSH ("ssh" by default).

  sucp DESCRIPTION
      csp_sucp calls cat(1) from within sudo(1) from within ssh(1). This allows one to copy files to accounts on hosts one can only reach by call-
      ing sudo on the ssh-reachable remote host.

      Typically, one wants to install a root-owned file, but one does not want to allow access to the root-account directly  from  ssh.  Typically
      sudo is used as an extra line of defense.

  sucp EXAMPLES
      Some examples:

	csp_sucp rms@bilbo /etc fstab

	csp_sucp monty-python commit/ trailer.txt

  sucp BUGS
      If  NOPASSWD  is	not  set in the sudoers(5) file, and one's timestamp is expired, csp_sucp will forward the sudo password prompt. The given
      password will be echoed on the console!
