RudiC's solution for Unix sed (that wants multi-line and a space after the w command and a ; before a })
With shell code
Now the experts question.
I am wondering if there could be a race condition - TMP is not yet flushed when cat opens it.
I think the order of the cat arguments makes it, first - then TMP.
But what happens if the stdout is closed before the TMP? And in the microsecond between the cat starts reading from TMP? Is this possible?
Can we find some of size of all files in a directry where file names start with an letter t*

Hi all.
I have 2 files like this:
f1
A 10
B 80
C 9
f2
A 11
B 700
C 10
What I want is the concatenation of the two files sorted by name (alphabetically) and size (numerically), so the result should be like this:
F3 (cat f1 f2 sorted)
A 10
A 11
B 80
B 700 (2 Replies)

shtool-mkshadow
SHTOOL-MKSHADOW.TMP(1) GNU Portable Shell Tool SHTOOL-MKSHADOW.TMP(1)NAME
shtool-mkshadow - GNU shtool create shadow tree using symlinks
SYNOPSIS
shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir
DESCRIPTION
This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating
the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via
relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to
create copies of source trees.
OPTIONS
The following command line options are available.
-v, --verbose
Display some processing information.
-t, --trace
Enable the output of the essential shell commands which are executed.
-a, --all
Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files,
etc.
EXAMPLE
# shell script
shtool mkshadow -v -a . /tmp/shadow
HISTORY
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later
revised and taken over into GNU shtool.
