+ This is Edition 5.2, last updated 11 April 2022, of 'The GNU Bash
Reference Manual', for 'Bash', Version 5.2.
Bash contains features that appear in other popular shells, and some
last command executed before the 'return'.
Variables local to the function may be declared with the 'local'
-builtin. These variables are visible only to the function and the
-commands it invokes. This is particularly important when a shell
-function calls other functions.
+builtin ("local variables"). Ordinarily, variables and their values are
+shared between a function and its caller. These variables are visible
+only to the function and the commands it invokes. This is particularly
+important when a shell function calls other functions.
+
+ In the following description, the "current scope" is a currently-
+executing function. Previous scopes consist of that function's caller
+and so on, back to the "global" scope, where the shell is not executing
+any shell function. Consequently, a local variable at the current local
+scope is a variable declared using the 'local' or 'declare' builtins in
+the function that is currently executing.
Local variables "shadow" variables with the same name declared at
previous scopes. For instance, a local variable declared in a function
variable is local to the current scope, 'unset' will unset it; otherwise
the unset will refer to the variable found in any calling scope as
described above. If a variable at the current local scope is unset, it
-will remain so until it is reset in that scope or until the function
-returns. Once the function returns, any instance of the variable at a
-previous scope will become visible. If the unset acts on a variable at
-a previous scope, any instance of a variable with that name that had
-been shadowed will become visible.
+will remain so (appearing as unset) until it is reset in that scope or
+until the function returns. Once the function returns, any instance of
+the variable at a previous scope will become visible. If the unset acts
+on a variable at a previous scope, any instance of a variable with that
+name that had been shadowed will become visible (see below how
+'localvar_unset'shell option changes this behavior).
Function names and definitions may be listed with the '-f' option to
the 'declare' ('typeset') builtin command (*note Bash Builtins::). The
'${PARAMETER:OFFSET:LENGTH}'
This is referred to as Substring Expansion. It expands to up to
LENGTH characters of the value of PARAMETER starting at the
- character specified by OFFSET. If PARAMETER is '@', an indexed
- array subscripted by '@' or '*', or an associative array name, the
- results differ as described below. If LENGTH is omitted, it
- expands to the substring of the value of PARAMETER starting at the
- character specified by OFFSET and extending to the end of the
+ character specified by OFFSET. If PARAMETER is '@' or '*', an
+ indexed array subscripted by '@' or '*', or an associative array
+ name, the results differ as described below. If LENGTH is omitted,
+ it expands to the substring of the value of PARAMETER starting at
+ the character specified by OFFSET and extending to the end of the
value. LENGTH and OFFSET are arithmetic expressions (*note Shell
Arithmetic::).
$ echo ${array[0]: -7:-2}
bcdef
- If PARAMETER is '@', the result is LENGTH positional parameters
- beginning at OFFSET. A negative OFFSET is taken relative to one
- greater than the greatest positional parameter, so an offset of -1
- evaluates to the last positional parameter. It is an expansion
- error if LENGTH evaluates to a number less than zero.
+ If PARAMETER is '@' or '*', the result is LENGTH positional
+ parameters beginning at OFFSET. A negative OFFSET is taken
+ relative to one greater than the greatest positional parameter, so
+ an offset of -1 evaluates to the last positional parameter. It is
+ an expansion error if LENGTH evaluates to a number less than zero.
The following examples illustrate substring expansion using
positional parameters:
than the maximum index of NAME, so negative indices count back from the
end of the array, and an index of -1 references the last element.
+ The '+=' operator will append to an array variable when assigning
+using the compound assignment syntax; see *note Shell Parameters::
+above.
+
Any element of an array may be referenced using '${NAME[SUBSCRIPT]}'.
The braces are required to avoid conflicts with the shell's filename
expansion operators. If the SUBSCRIPT is '@' or '*', the word expands
'read', the trap handler executes and 'read' returns an exit status
greater than 128.

+ 60. The 'printf' builting uses 'double' (via 'strtod') to convert

+ 61. Bash removes an exited background process's status from the list
of such statuses after the 'wait' builtin is used to obtain it.
There is other POSIX behavior that Bash does not implement by default
non-incremental history searches. The default is 'On'.
'enable-bracketed-paste'
- When set to 'On', Readline will configure the terminal in a
- way that will enable it to insert each paste into the editing
- buffer as a single string of characters, instead of treating
- each character as if it had been read from the keyboard. This
- can prevent pasted characters from being interpreted as
- editing commands. The default is 'On'.

Bash contains features that appear in other popular shells, and some
'read', the trap handler executes and 'read' returns an exit status
greater than 128.
- 60. Bash removes an exited background process's status from the list
+ 60. The 'printf' builting uses 'double' (via 'strtod') to convert

of such statuses after the 'wait' builtin is used to obtain it.
There is other POSIX behavior that Bash does not implement by default
