A coroutine (two-way pipe) seems to be overkill, since you are not waiting for the remote user/password prompt.
To do such a simple thing a here-document is enough:
The problem could be that you send the password too early.
If you are willing to wait for a password prompt then you need a two-way pipe and have to read -p before print -p.
Hello everybody,
I have a question about I/O redirection within a coprocess.
I want to setup a coprocess and then redirect output to a file on a remote machine.
Here's some Perderabo code modified

I am wracking my brains over this. I am trying to use a Korn Shell script to execute an Oracle PL/SQL procedure, using the Oracle command line interface (sqlplus). The script starts sqlplus in a coprocess, and the two processes communicate using a two-way pipe. The bgnice option is off, so both... (8 Replies)
Hi all,
Just like to ask if it is possible to do the following:
1. Have a shell script that calls ssh username@destinationhost
2. Upon successful verification, we ssh into the destination host and automatically use ksh to run a shell script that resides in the destination host. (Hopefully no... (8 Replies)
Hi can any one let me know if awk doesnt work with the coprocess??? I have tried a simple example mentioned below but couldnt get it working seems like awk doesnt work with the coprocess concept. I would appreciate very much for any inputs on this.

Is there a way to shorten these commands? because this script asks for a password 3 times
scp -p /usr/local/bin/${script_name} ${servername$iy]}://usr/local/bin/
ssh ${servernames} /usr/local/bin/${script_name}
ssh ${servernames} rm -f /usr/local/bin/${script_name}
Basically, I'm creating a... (3 Replies)
This is probably a simple one for the wise.
I have just started using a coprocess (first time) in order to facilitate telnet'ing from inside a shell script. It's working, but when I run a remote command I need to get the output into a local variable, but alas my kung-fu is weak.

While assisting a forum member, I recommended running SQL/Plus in a coprocess (to make database connections and run a test script) for the duration of his script rather than starting/stopping it once for every row in a file he was processing.
I recalled I made a coprocess example for folks at... (2 Replies)

csp_scp_keep_mode
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!
