send y /n to a procces after itīs running
Hello

Iīm a senior Unix technician, i have a problem: I need send "y" and "enter" to a proccess that are running in memory. I explain that.

I have a server with Suse 10.3 that itīs runnig informix 11.10, this server are a backup server of a database server, to ensure the integrity of data y need execute a command "ontape -l" this command is interactive, and ask you to send a "yes enter" when you change the backup tape.

Mi problem is that command can interrup, because itīs change the state of database when itīs aborted, well i need make script to execute dayli that send "yes enter" to this proccess.

I try redirectin standard input, but this itīs only valid for one execution, example:

temp.txt
[status printer1
stop printer 2
]

serverBD:/DATA/LOGS # lpc < kk.txt
lpc> hpmater1:
printer is on device 'socket' speed -1
queuing is enabled
printing is enabled
no entries
daemon present
lpc> hpmater11:
printer is on device 'socket' speed -1
queuing is enabled
printing is enabled
no entries
daemon present

but this solution not solve my problem because, i need lpc running always

I try with jobs, making invoke call similar to:

echo "y \n"|fg pid

but Iīm not capable to make it works

anyone have a idea?, how i can send "y n" to a proccess that have standar input in shell and can not be aborted never.

Very very thanks.

send-nntp

SEND-UUCP(8)						      System Manager's Manual						      SEND-UUCP(8)

NAME

       send-nntp, send-ihave - send Usenet articles to remote site

SYNOPSIS

       send-nntp [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename ..	]

       send-ihave [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename ..  ]

DESCRIPTION

       The send-* utilities are scripts that process the batch files written by innd(8) to send Usenet articles to a remote NNTP site.

       The sites to be fed may be specified by giving sitename hostname pairs on the command line.

       The sitename is the label the site has in the newsfeeds file, the hostname is the real hostname of the remote site, a FQDN (Fully Qualified
       Domain Name).  Normally, the sitename and the hostname are the same, and as such don't have to be specified as sitename:hostname pairs  but
       just as a sitename.

       send-nntp starts an innxmit to send the articles to the remote site.

       send-ihave  encapsulates  the articles in an ihave control message and uses inews to send the articles to a to.sitename pseudo-group. Using
       send-ihave is discouraged, nobody uses it anymore and even the author of this manpage is unsure as to how it  actually  works  or  used	to
       work.

       send-*  expect  that  the batchfile for a site is named <pathoutgoing in inn.conf>/sitename.  To prevent batchfile corruption, shlock(1) is
       used to ``lock'' these files.

OPTIONS

       -d     The ``-d'' flag causes nntpsend to send output to stdout rather than the log file <pathlog in inn.conf>/<program-name>.log.

NOTES

       You should probably not use send-nntp, but innfeed, or if that is not possible, nntpsend.

       The usual flags for a batch file for send-nntp are ``Tf,Wfm''.
