"infix" version in bash (4.x+)

Remove -v to make it silent.

BTW: The OP forgot to use "cat" and "nmap" ;-) I had a good laugh though.

buf () { cp $1{,$(date +%Y%m%d_%H%M%S)}; }

1. you don't need to prepend the year with 20 - just use Y instead of y

2. you may want to make your function a bit more secure:

buf () { cp ${1?filename not specified}{,$(date +%Y%m%d_%H%M%S)}; }

read -a ARR <<<'world domination now!'; echo ${ARR[2]};
read -a A <<<"8 9 5 10 6 0 3 11 7 4";B='.*.**..*....***';for C in $(date +"%H%M"|fold -w1);do echo "${B:${A[C]}:4}";done
for a in $(date +"%H%M"|cut -b1,2,3,4 --output-delimiter=" ");do case "$a" in 0)echo "....";;1)echo "...*";;2)echo "..*.";;3)echo "..**";;4)echo ".*..";;5)echo ".*.*";;6)echo ".**.";;7)echo ".***";;8)echo "*...";;9)echo "*..*";;esac;done

I used 110 as the port number in examples for clarity.

backslash+lessthan or backslash+b marks 'edge of the word'.

displays current time in "binary clock" format

(loosely) inspired by: http://www.thinkgeek.com/homeoffice/lights/59e0/

"Decoding":

8421

.... - 1st hour digit: 0

*..* - 2nd hour digit: 9 (8+1)

.*.. - 1st minutes digit: 4

*..* - 2nd minutes digit: 9 (8+1)

Prompt-command version:

PROMPT_COMMAND='echo "10 i 2 o $(date +"%H%M"|cut -b 1,2,3,4 --output-delimiter=" ") f"|dc|tac|xargs printf "%04d\n"|tr "01" ".*"'

no need to reinvent the wheel.

Thanks to the OP for the "obsolete" hint. 'declare' may come in pretty handy on systems paranoid about "up-to-dateness"

PROMPT_COMMAND='seq $COLUMNS | xargs -IX printf "%Xs\r" @'

Used it on daily basis, not sure if it's any better than the OPs version, tho'

One advantage is - you can replace 'bash' at the end of the line with eg. cat - to check if the generated command is OK.

awk 'func f(n){return(n<2?n:f(n-1)+f(n-2))}BEGIN{while(a<24){print f(a++)}}'

pushd and popd are your friends, but sometimes they're just incompatible with the way one works...

Two shell functions:

bm bookmarkname - "bookmarks" the current directory, just 'cd $BMbookmarkname' to return to it.

forget bookmarkname - unsets the 'bookmarkname' variable. It isn't mandatory, they cease to exist when the session ends.

echo "e("{1..8}");" | bc -l
mv -- -filename filename
