Ok i see you had did a read -p 'Please type ation:' x, that is not visible here .
You can either make sure the provided char inputs are non-caps, or use regex to catch both at once.
1) Make it small (is this posix?)
Code:
x=A
x=${x,,}
[ $x = a ] && echo "Add"
2) Or use Regex:
Code:
x=a
[ $x = [aA] ] && echo "Add"
Use either 1. or 2., this will save you from using if [ $x == 'B' -o $x == 'b' ] ; then for each of the A-F.
3) For menus or comparing 1 value with diffrent options, its quite easier to use a case statement
Code:
case $x in
a) echo "do add" ;;
b) echo "do sub" ;;
esac
4) Could use Regex here too (= instead)
Code:
case $x in
a|A) echo "do add" ;;
[bB]) echo "do sub" ;;
esac
edit: 5. Quotes:
I'd rather make the quotes around the variables, than around the letters.
If the variable is empty, or contains a special char (like arrow-up) it will produce and error message, rather than just not execute (as in not true ; not matching).

Locale::Codes::LangExt(3pm) Perl Programmers Reference Guide Locale::Codes::LangExt(3pm)NAME
Locale::Codes::LangExt - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangExt;
$lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic'
$code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langext_codes();
@names = all_langext_names();
DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. 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:
$lext = code2langext('acm','alpha');
$lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.
This is the default code set.
ROUTINES
code2langext ( CODE [,CODESET] )
langext2code ( NAME [,CODESET] )
langext_code2code ( CODE ,CODESET ,CODESET2 )
all_langext_codes ( [CODESET] )
all_langext_names ( [CODESET] )
Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] )
Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME )
Locale::Codes::LangExt::delete_langext_alias ( NAME )
Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
