Let the script name is x.sh
Below are some of the codes in it...
When i am trying to compile the script
I did some preliminiary research and from the "man bash" found out that
"Array variables may not (yet) be exported"
I am trying to find a work around for it.

Reason: added code tags
I am exporting data using a shell program. I am getting all of the records instead of getting a subset based on my query. The export_problem.par lists all of my tables. I tried the query with the ' and without it. How do I get the export to use the query?
Thanks!

Everything else seems to be working, but this isn't. Is it the "cat..." that is wrong of the condition? Thanks.

It is happening with my sessions already second time: a 'for'-loop for some reason stop to work as expected.
That means or it is looping without exitting, or it is not loop even once.

Hello all,
How can I invoke the bash shell (via command line) to execute another command by setting an exported environmental variable on the fly (as this env var would be used by the command -another script, the bash would execute).
This needs to be done in one single line as the same would... (4 Replies)
Hi,

lksh
LKSH(1) BSD General Commands Manual LKSH(1)NAME
lksh -- Legacy Korn shell built on mksh
SYNOPSIS
lksh [-+abCefhiklmnprUuvXx] [-+o opt] [-c string | -s | file [args ...]]
DESCRIPTION
lksh is a command interpreter intended exclusively for running legacy shell scripts. It is built on mksh; refer to its manual page for
details on the scripting language. It is recommended to port scripts to mksh instead of relying on legacy or idiotic POSIX-mandated behav-
iour, since the MirBSD Korn Shell scripting language is much more consistent.
LEGACY MODE
lksh has the following differences from mksh:
o lksh is not suitable for use as /bin/sh.
o There is no explicit support for interactive use, nor any command line editing or history code. Hence, lksh is not suitable as a user's
login shell, either; use mksh instead.
o The KSH_VERSION string identifies lksh as ``LEGACY KSH'' instead of ``MIRBSD KSH''.
o lksh only offers the traditional ten file descriptors to scripts.
o lksh uses POSIX arithmetics, which has quite a few implications: The data type for arithmetics is the host ISO C long data type. Signed
integer wraparound is Undefined Behaviour. The sign of the result of a modulo operation with at least one negative operand is unspeci-
fied. Shift operations on negative numbers are unspecified. Division of the largest negative number by -1 is Undefined Behaviour. The
compiler is permitted to delete all data and crash the system if Undefined Behaviour occurs.
o The rotation arithmetic operators are not available.
o The shift arithmetic operators take all bits of the second operand into account; if they exceed permitted precision, the result is
unspecified.
o The GNU bash extension &> to redirect stdout and stderr in one go is not parsed.
o The mksh command line option -T is not available.
o Unless set -o posix is active, lksh always uses traditional mode for constructs like:
$ set -- $(getopt ab:c "$@")
$ echo $?
POSIX mandates this to show 0, but traditional mode passes through the errorlevel from the getopt(1) command.
o lksh, unlike AT&T UNIX ksh, does not keep file descriptors > 2 private.

CAVEATS
lksh tries to make a cross between a legacy bourne/posix compatibl-ish shell and a legacy pdksh-alike but ``legacy'' is not exactly speci-
fied.
The set built-in command does not have all options one would expect from a full-blown mksh or pdksh.
Talk to the MirOS development team using the mailing list at <miros-mksh@mirbsd.org> or the #!/bin/mksh (or #ksh) IRC channel at
irc.freenode.net (Port 6697 SSL, 6667 unencrypted) if you need any further quirks or assistance, and consider migrating your legacy scripts
to work with mksh instead of requiring lksh.
