Could anyone please explain why it organizations prefer korn shell instead of bash shell. Thanks!
OK, just one of the most annoying differences.
Suppose the following command lines, which could also be part of a script:
What is the content of "$x" after the loop? I every programming language i know (and ksh as well) it is "a b c". In bash it will be "" (empty string), because the content of "$x" is somewhat local to the code block. Notice the difference in the first "echo $x" and the last line.
Of course it would be possible to prevent this by replacing the pipeline with a redirection:
but i would like my while-loops not to be steered at the bottom. It is just hard to read if the loop is longer and you have to go three pages down to find out what is fed into the loop, then go back up to see what is done with the input.

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.
