I use the script like this:
./RetrieveID.ksh filein fileout
everytime as soon as dbFindChannel successed, the script exit. So it can only retrieve the first channel new id, but not all the successful one. Do I miss something here? Why did the script exit the while loop even in the <filein>, there are a lot of channel remains.
script that ask for "enter a file name" and removes that file
and asks for confirmation before deletion
if executed the output might look as
enter the filename you intent to deleted
remover file? Y

Hi,
First, let me explain the issue I am trying to solve. We have a lot of expect scripts with the duplicated send/expect commands. So, I'd like to be able to extract the duplicated code into the common scripts that can be used by other scripts.

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
