Using tee causing need for extra newlines.
I am working on capturing lines of output from a korn script that is used to import optical disks into a jukebox. The script is running on Solaris 8. Insertdiscs calls the binary named vimport which starts up and prompts for a disk to be inserted. I am able to capture output with this line below which would be perfect except that as soon as insertdiscs is piped to tee (as opposed to running it alone) I need to hit enter twice to get it to start vimport (see below) for each loop.

Code:
#!/bin/bash
#In Solaris 8 only bash handles the below process substitution properly.
 insertdiscs | tee >(egrep Imported\|INFO >> /tmp/importdisclog.txt)

I have tried
Code:
printf "\n" | insertdiscs | tee >(egrep Imported\|INFO >> /tmp/importdisclog.txt)

as well as piping from echo "\n" and all that gets me is infinite new lines at every prompt from the interactive vimport script.


This is the insertdiscs script that is called from my code above:
Code:
#!/bin/ksh
while [ $TRUE ]
do
  vimport -j 1
  rc=$?
  if [ $rc -eq 0 ]; then
    log_message "G" "Volume import succeeded for jukebox using insertdiscs."
  else
    log_message "B" "Volume import failed for jukebox using insertdiscs."
  fi
done

Any help appreciated.
Thanks,
Brett

locale::codes::script5.18

Locale::Codes::Script(3pm)				 Perl Programmers Reference Guide				Locale::Codes::Script(3pm)

NAME

       Locale::Codes::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Codes::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Codes::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. A code set may be specified using either a name, or a constant
       that is automatically exported by this module.

       For example, the two are equivalent:

	  $script = code2script('phnx','alpha');
	  $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_SCRIPT_ALPHA
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.  It also includes additions to this set
	   included in the IANA language registry.

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       num, LOCALE_SCRIPT_NUMERIC
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Codes::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Codes::Script::delete_script  ( CODE [,CODESET] )
       Locale::Codes::Script::add_script_alias	( NAME ,NEW_NAME )
       Locale::Codes::Script::delete_script_alias  ( NAME )
       Locale::Codes::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Script::delete_script_code_alias	( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
