You may have been mislead by some of my guesses at what might be going on. The original statement was that the command:
(note the single set of parentheses) when processed by an unspecified version of the Korn shell produces the output
Note that psychocandy has yet to answer the question: What does the command
produce on a system where echo $(5.2+2.5) prints 6?

I am writing a script to keep check on free disk space, and I would like to find a way to parse $LINE (see code below) into a numeric value (for free disk space percentage) and a string value (for mount point). If possible, I would like to avoid sed or any additional use of awk since I am not very... (7 Replies)

sh(1) General Commands Manual sh(1)NAME
sh - overview of various system shells
SYNOPSIS
POSIX Shell
option] ... string] [arg ...]
option] ... string] [arg ...]
Korn Shell
option] ... string] [arg ...]
option] ... string] [arg ...]
C Shell
[command_file] [argument_list ...]
Key Shell
DESCRIPTION
Remarks
The POSIX .2 standard requires that, on a POSIX-compliant system, executing the command activates the POSIX shell (located in file on HP-UX
systems), and executing the command produces an on-line manual entry that displays the syntax of the POSIX shell command-line.
However, the command has historically been associated with the conventional Bourne shell, which could confuse some users. To meet stan-
dards requirements and also clarify the relationships of the various shells and where they reside on the system, this entry provides com-
mand-line syntax and a brief description of each shell, and lists the names of the manual entries where each shell is described in greater
detail.
The Bourne shell is removed from the system starting with HP-UX 11i Version 1.5. Please use the POSIX shell as an alternative.
Shell Descriptions
The HP-UX operating system supports the following shells:
POSIX-conforming command programming language and command interpreter
residing in file Can execute commands read from a terminal or a file. This shell conforms to current POSIX standards in
effect at the time the HP-UX system release was introduced, and is similar to the Korn shell in many respects. Similar in
many respects to the Korn shell, the POSIX shell contains a history mechanism, supports job control, and provides various
other useful features.
Korn-shell command programming language and commands interpreter
residing in file Can execute commands read from a terminal or a file. This shell, like the POSIX shell, contains a his-
tory mechanism, supports job control, and provides various other useful features.
A command language interpreter
that incorporates a command history buffer, C-language-like syntax, and job control facilities.
Restricted version of the POSIX shell command interpreter.
Sets up a login name and execution environment whose capabilities are more controlled (restricted) than normal user
shells.
restricted version of the Korn-shell command interpreter
Sets up a login name and execution environment whose capabilities are more controlled (restricted) than normal user
shells.
An extension of the standard Korn Shell
that uses hierarchical softkey menus and context-sensitive help.
+--------------+--------------------+
| To obtain: | Use the command: |
+--------------+--------------------+
| POSIX Shell | /usr/bin/sh ... |
| Korn Shell | /usr/bin/ksh ... |
| C Shell | /usr/bin/csh ... |
| Key Shell | /usr/bin/keysh |
+--------------+--------------------+
These shells can also be the default invocation, depending on the entry in the file. See also chsh(1).
WARNINGS
Many manual entries contain descriptions of shell behavior or describe program or application behavior similar to ``the shell'' with a ref-
erence to ``see sh(1)''.
