Linux Simple

Fight Patents abuse by EC authorities - newamericancentury (indeed...) - Gegen Patentmißbrauch durch die EU-Behörden.

A few simple shellscripts which helped me getting hands on the Linux System...
many english docs, "HOWTO"s etc exist, already, thus much more in the german version

POP3-Filter
and the 2nd-ary filter "p3f", which is a "lib4th" example program used by "POP3-Filter", help getting rid of silly 'adverts' and other such stupid stuff in an easily configureable manner; applicable before actually receiving the (remaining) e-mails with a 'normal' reader.
POP3Filter - to which (yet?) no english docs are available - is a Perl program, which sends the mail header and the leading lines, as configured and received by the "TOP" pop3 command to the 2nd-ary filter and expects the return code 0 if it should delete the rsp. message; any other error code will be recived as a signal to not 'DELE'ting. This most simple decision rule enables filter scripts by any programming language, as convenient. - "p3f" is an experimental Forth script, demonstrating some of the "lib4th" string handling words and, scripting; very simple, useable but, not thoroughly tested...
The filter can be used as a 'precommand' for the KMail client (KDE), 'Network', 'Incoming Mail' configuration.
MK-allman
a group of short shell script to generating a linked w/ other man-sections index file, browsable w/ "pinfo", of the rsp man-directory where it was invoked from and, html-versions of the rsp. man-pages, eg.g for reference from within the "syscalls" pages..
fd
One of the greatest difficulties was just finding a certain program or a document supposed to be somewhere in the system but, due to the perfect file system standard which equally perfectly seems always to be superseded by certain distributors superior knowledge ("SuSE"!) were undiscoverably hidden. This could be solved with "find" which does everything and a lot more - which was made to preferably confuse any beginners to thus giving some splendour on those who succeed... :-((
"fd" grew out of my needs to greatly simplify the procedure and reduce the parameters to the most frequently needed. It always recurses (dives) into sub-directories. And because of the most confusing, stupid and quite annoying mannerism of filenames spelling with nicely intermixed capital and small letters, it always takes file/directory/path names and search-text case independently:
```
	searching the current working directory (c.w.d.):
	fd filename
	
	searching a certain directory, relative to c.w.d.:
	fd path filename

	searching a certain directory, absolute (beginning at "/"):
	fd /path filename

	searching for some content of some file in c.w.d.:
	fd "*" "content_text"
	
	same for partly known filenames where a certain text is suspected:
	fd "file*" "content_text"
```
I.e. syntax is:
```
	fd [ searchpath ] filename [ content ]
```
If any parameter contains characters which the shell would expand to something else, the asterisk "*", blank spaces, etc, the parameter concerned should be quoted (enclosed in double quotes <">).
"fd" requires "extname" (included) from "asmutils", which can be substituted, though - re file "fd".
hd-mount
tool to automattedly mount and unmount any accessible ext2/ext3(Linux) or dos/vfat (mickeysoft-ware) partitions to temporary directories - re file for further description.

Bash Shell Functions can be built from any independently executeable sequence of shell commands:

		# ---- convert any radix' number, build & echo any radix result string ----
		#	dot "radix_in#number" radix_out
		#	dot number radix_out	# implies decimal input
		#	dot number		# implies decimal   " & output
		# ---- < dot "36#MAUS" 16 > returns < fe074 > ----
		function dot () {
		   local num="$((${1}))" radix="$2" sign digit
		   [ -z "${radix}" ]&&radix=10
		   result=""
		   if [ $((num)) ];then
		      [ "${num}" == "${num#*-}" ]||{ sign="-";num=${num#*-}; }
		      while [ $((num)) ]
		      do
		         digit=$((num % radix))
		         num=$((num/radix))
		         [ $((${digit})) -gt $((9)) ]&&digit=$((digit+39))
		         result=$(echo -en "\x$(printf %x $(($digit+48)))")$result
		      done
		      result=$sign$result
		   else
		      result="0"
		   fi
		echo
		   echo $result
		}

fb - framebuffer - is some "advanced" entity in development state, most obviosly planned to become quite a promising substitute of the long time missing mickeysoft style of resources useage, to wasting whatever can be and to every possible extent, memory, swapspace, system resources and, users's time! - it doesn't offer anything which could be suspected to compensating those advanced features.
Which, once experienced, will certainly remain known. So the short patch, below, was made to fighting pengin abuse, suppressing its appearance ever so often at each system start, and to leaving the sometimes much more valuable system messages in place:
