+Bash-4.2 contains the following new features (see the manual page for

 distribution):
 
+o   `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+    leading #!.
+
+o   Subshells begun to execute command substitutions or run shell functions or
+    builtins in subshells do not reset trap strings until a new trap is
+    specified.  This allows $(trap) to display the caller's traps and the
+    trap strings to persist until a new trap is set.
+
+o   `trap -p' will now show signals ignored at shell startup, though their
+    disposition still cannot be modified.
+
+o   $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+o   declare/typeset has a new `-g' option, which creates variables in the
+    global scope even when run in a shell function.
+
+o   test/[/[[ have a new -v variable unary operator, which returns success if
+    `variable' has been set.
+
+o   Posix parsing changes to allow `! time command' and multiple consecutive
+    instances of `!' (which toggle) and `time' (which have no cumulative
+    effect).
+
+o   Posix change to allow `time' as a command by itself to print the elapsed
+    user, system, and real times for the shell and its children.
+
+o   $((...)) is always parsed as an arithmetic expansion first, instead of as
+    a potential nested command substitution, as Posix requires.
+
+o   A new FUNCNEST variable to allow the user to control the maximum shell
+    function nesting (recursive execution) level.
+
+o   The mapfile builtin now supplies a third argument to the callback command:
+    the line about to be assigned to the supplied array index.
+
+o   The printf builtin has as new %(fmt)T specifier, which allows time values
+    to use strftime-like formatting.
+
+o   There is a new `compat41' shell option.
+
+o   The cd builtin has a new Posix-mandated `-e' option.
+
+o   Negative subscripts to indexed arrays, previously errors, now are treated
+    as offsets from the maximum assigned index + 1.
+
+o   Negative length specifications in the ${var:offset:length} expansion,
+    previously errors, are now treated as offsets from the end of the variable.
+
+o   Parsing change to allow `time -p --'.
+
+o   Posix-mode parsing change to not recognize `time' as a keyword if the
+    following token begins with a `-'.  This means no more Posix-mode
+    `time -p'.  Posix interpretation 267.
+
+o   There is a new `lastpipe' shell option that runs the last command of a
+    pipeline in the current shell context.  The lastpipe option has no
+    effect if job control is enabled.
+
+o   History expansion no longer expands the `$!' variable expansion.
+
+o   Posix mode shells no longer exit if a variable assignment error occurs
+    with an assignment preceding a command that is not a special builtin.
+
+o   Non-interactive mode shells exit if -u is enabled an an attempt is made
+    to use an unset variable with the % or # expansions, the `//', `^', or
+    `,' expansions, or the parameter length expansion.
+
+o   Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+    fails, effectively searching the current directory.  Posix-2008 change.

+GNU Parallel, as its name suggests, can be used to build and run commands
+in parallel.  You may run the same command with different arguments, whether
+they are filenames, usernames, hostnames, or lines read from files.
+</P><P>
+
+For a complete description, refer to the GNU Parallel documentation.  A few
+examples should provide a brief introduction to its use.
+</P><P>
+
+For example, it is easy to prefix each line in a text file with a specified
+string:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>cat file | parallel -k echo prefix_string
+</pre></td></tr></table>The <SAMP>`-k'</SAMP> option is required to preserve the lines' order.
+</P><P>
+
+Similarly, you can append a specified string to each line in a text file:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>cat file | parallel -k echo {} append_string
+</pre></td></tr></table></P><P>
+
+You can use Parallel to move files from the current directory when the
+number of files is too large to process with one <CODE>mv</CODE> invocation:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>ls | parallel mv {} destdir
+</pre></td></tr></table></P><P>
+
+As you can see, the {} is replaced with each line read from standard input.
+This will run as many <CODE>mv</CODE> commands as there are files in the current
+directory.  You can emulate a parallel <CODE>xargs</CODE> by adding the <SAMP>`-X'</SAMP>
+option:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>ls | parallel -X mv {} destdir
+</pre></td></tr></table></P><P>
+
+GNU Parallel can replace certain common idioms that operate on lines read

+3.2.6 GNU Parallel
+------------------
+
+GNU Parallel, as its name suggests, can be used to build and run
+commands in parallel.  You may run the same command with different
+arguments, whether they are filenames, usernames, hostnames, or lines
+read from files.
+
+   For a complete description, refer to the GNU Parallel documentation.
+A few examples should provide a brief introduction to its use.
+
+   For example, it is easy to prefix each line in a text file with a
+specified string:
+     cat file | parallel -k echo prefix_string
+   The `-k' option is required to preserve the lines' order.
+
+   Similarly, you can append a specified string to each line in a text
+file:
+     cat file | parallel -k echo {} append_string
+
+   You can use Parallel to move files from the current directory when
+the number of files is too large to process with one `mv' invocation:
+     ls | parallel mv {} destdir
+
+   As you can see, the {} is replaced with each line read from standard
+input.  This will run as many `mv' commands as there are files in the
+current directory.  You can emulate a parallel `xargs' by adding the
+`-X' option:
+     ls | parallel -X mv {} destdir
+
+   GNU Parallel can replace certain common idioms that operate on lines
+read from a file (in this case, filenames):
+     	for x in $(cat list); do
+     		do-something1 $x config-$x
+     		do-something2 < $x
+     	done | process-output
+
+with a more compact syntax reminiscent of lambdas:
+     cat list | parallel "do-something1 {} config-{} ; do-something2 < {}" | process-output
+
+   Parallel provides a built-in mechanism to remove filename
+extensions, which lends itself to batch file transformations or
+renaming:
+     ls *.gz | parallel -j+0 "zcat {} | bzip2 >{.}.bz2 && rm {}"
+   This will recompress all files in the current directory with names
+ending in .gz using bzip2, running one job per CPU (-j+0)  in parallel.
+
+   If a command generates output, you may want to preserve the input
+order in the output.  For instance, the following command
+     { echo foss.org.my ; echo debian.org; echo freenetproject.org; } | parallel traceroute
+   will display as output the traceroute invocation that finishes
+first.  Using the `-k' option, as we saw above
+     { echo foss.org.my ; echo debian.org; echo freenetproject.org; } | parallel -k traceroute
+   will ensure that the output of `traceroute foss.org.my' is displayed
+first.

+@node GNU Parallel
+@subsection GNU Parallel
+
+GNU Parallel, as its name suggests, can be used to build and run commands
+in parallel.  You may run the same command with different arguments, whether
+they are filenames, usernames, hostnames, or lines read from files.
+
+For a complete description, refer to the GNU Parallel documentation.  A few
+examples should provide a brief introduction to its use.
+
+For example, it is easy to prefix each line in a text file with a specified
+string:
+@example
+cat file | parallel -k echo prefix_string
+@end example
+@noindent
+The @option{-k} option is required to preserve the lines' order.
+
+Similarly, you can append a specified string to each line in a text file:
+@example
+cat file | parallel -k echo @{@} append_string
+@end example
+
+You can use Parallel to move files from the current directory when the
+number of files is too large to process with one @code{mv} invocation:
+@example
+ls | parallel mv @{@} destdir
+@end example
+
+As you can see, the @{@} is replaced with each line read from standard input.
+This will run as many @code{mv} commands as there are files in the current
+directory.  You can emulate a parallel @code{xargs} by adding the @option{-X}
+option:
+@example
+ls | parallel -X mv @{@} destdir
+@end example
+
+GNU Parallel can replace certain common idioms that operate on lines read
+from a file (in this case, filenames):
+@example
+	for x in $(cat list); do
+		do-something1 $x config-$x
+		do-something2 < $x
+	done | process-output
+@end example
+
+@noindent
+with a more compact syntax reminiscent of lambdas:
+@example
+cat list | parallel "do-something1 @{@} config-@{@} ; do-something2 < @{@}" | process-output
+@end example
+
+Parallel provides a built-in mechanism to remove filename extensions, which
+lends itself to batch file transformations or renaming:
+@example
+ls *.gz | parallel -j+0 "zcat @{@} | bzip2 >@{.@}.bz2 && rm @{@}"
+@end example
+@noindent
+This will recompress all files in the current directory with names ending
+in .gz using bzip2, running one job per CPU (-j+0)  in parallel.
+
+If a command generates output, you may want to preserve the input order in
+the output.  For instance, the following command
+@example
+@{ echo foss.org.my ; echo debian.org; echo freenetproject.org; @} | parallel traceroute
+@end example
+@noindent
+will display as output the traceroute invocation that finishes first.  Using
+the @option{-k} option, as we saw above
+@example
+@{ echo foss.org.my ; echo debian.org; echo freenetproject.org; @} | parallel -k traceroute
+@end example
+@noindent
+will ensure that the output of @code{traceroute foss.org.my} is displayed first.
