NAME

csp_helper - A collection of caspar helper scripts

SYNOPSIS

csp_install file (file) dir (directory)

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

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

DESCRIPTION

The scripts csp_install, 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 caspar(7) for information on how to link csp_install,
csp_scp_keep_mode and csp_sucp to caspar (FIXME).

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 index.html /srv/www

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

install ENVIRONMENT

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

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).
(FIXME: add rationale).

scp_keep_mode EXAMPLES

FIXME

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 calling 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 fstab rms@bilbo /etc

  csp_sucp trailer.txt monty-python commit/ list

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!
