KSH to Bash conversion

KSH to Bash conversion

[Galen Boyer]

In KSH, I have the following statement:

typeset -u TableName=$2

Then, I was assured that immdiately when the parameter was
recieved by the script it was converted to uppercase.  I need the
corresponding statement in Bash.

Thanks,

Unfortunately this is OT for this mailing list. Please ask on
a mailing list which cares for bash or shell programming in
general.

Thanks,

Galen,

It looks like BASH once had a typeset built-in, but no more. However, it 
apparently never supported a "-u" option:

--====----====----====----====----====----====----====----====----====----====--
1004> help typeset
typeset: typeset [-afFrxi] [-p] name[=value] ...
     Obsolete.  See `declare'.

1005> help declare
declare: declare [-afFrxi] [-p] name[=value] ...
     Declare variables and/or give them attributes...

     The flags are:
       -a        to make NAMEs arrays (if supported)
       -f        to select from among function names only
       -F        to display function names without definitions
       -r        to make NAMEs readonly
       -x        to make NAMEs export
       -i        to make NAMEs have the `integer' attribute set
     ....
--====----====----====----====----====----====----====----====----====----====--


So, knowing no more "direct" solution here's what I'd do:

1008> "var=UpPeR- AnD LoWeR-CaSe"
1009> echo $var
UpPeR- AnD LoWeR-CaSe

1010> uVar="$(echo "$var" |tr 'a-z' 'A-Z')"
1011> echo $uVar
UPPER- AND LOWER-CASE

1012> lVar="$(echo "$var" |tr 'A-Z' 'a-z')"
1013> echo $lVar
upper- and lower-case

THIS IS DEFINITELY OFF TOPIC. Please don't ask more bash questions here.

Anyway since you have done your noise, here are some answers.

1. To convert to upper case you can use `tr' like this:
       TableName=`echo "$2" | tr "[a-z]" "[A-Z]"`
   Please note all the " and ` - they are essential.

2. Echo of escaped (backslashed) characters.
   Beside the -e argument you can:
   2.1  Use /bin/echo
   2.2  Set the xpg_echo option (shopt -s xpg_echo)
   2.3  Compile bash with --enable-usg-echo-default

Remember in Cygwin sh is not bash (it is ash). You can change this by
removing/renaming sh and sym-linking bash to sh (that's what I do).

I STRONGLY suggest you read the bash man page(s) carefully.

Ehud.

Actually, using Emacs, I searched the man page for about 1/2
hour, looking for things like, upcase, convert and ...  Actually,
I do read manuals quite religiously, but I also search manuals
quite religiously.  Almost all of the time, your efforts aren't
rewarded and newsgroups help out.  Everyonce in awhile, your
efforts aren't rewarded because you were dense.  The latter
happened here.

I apologize profusely.   

I am well aware that off-topic is taboo.  Be assured that this
won't happen again.

Signing off with my tail between my legs.
