Top Forums Shell Programming and Scripting Using tee causing need for extra newlines. Post 302551698 by buggin on Wednesday 31st of August 2011 10:17:28 AM

Thanks hfreyer. I don't think I described the problem very well. Basically my insertdiscs script calls the vimport binary in a loop which is always running in a terminal. vimport is an interactive program that prompts to insert magnetic optical disks in a jukebox one at a time (enter slot number or hit enter at prompts for next available jukebox slot). The screen output for vimport has information that I need to also capture to a file (egrep Imported\|INFO). So in order to still see the interactive text from vimport to load disks and also capture parts of the output to file for processing I can start the script with:
Code:
insertdiscs | tee >(egrep Imported\|INFO >> /tmp/importdisclog.txt)

Except now I have to hit enter an extra time to get back to the beginning of the loop running vimport. Piping to tee adds the need for an extra enter key press. So I was hoping to somehow automatically add one enter key press or for some other solution. Otherwise the script always looks like it has hung when in fact it is ready to insert the next disk (after hitting enter an extra time to see the "please insert disk" prompt again).
Piping from print "\n" or (sleep 1; print "\n") sends too many newlines, I was hoping for some way to just send one if possible. Unfortunately the system is an old Sun box running Sun 5.8 so no expect.

lmfsetup(8)						      System Manager's Manual						       lmfsetup(8)

Name
       lmfsetup - License Management Facility PAK registration script

Syntax
       /etc/lmfsetup [ template ]

Description
       The  script allows you to register data supplied by a Product Authorization Key (PAK).  The script prompts you for the data associated with
       each of the fields on a PAK.  When all the data has been entered, the License Management Facility (LMF) ensures there are  entries  against
       all  the mandatory fields, and that the Checksum validates all the license data.  If the data has been entered correctly, the PAK is regis-
       tered in the License Database.  If the data has been entered incorrectly, the appropriate error message is displayed and you are given  the
       opportunity to re-enter the data.

       The template option allows you to register license data from templates in A template containing a partially complete PAK is created by some
       products as part of their installation process.	The script only prompts you for data on the fields that are empty in the template.  If the
       script cannot find the specified template in it searches the current directory.

       The  script  is	provided as an alternative to the command.  This displays a template, which includes the fields on the PAK, and invokes an
       editor so that you can add the license data to the appropriate field.  The command also allows errors to be corrected without having to re-
       enter all the data.
