OK Long script here, but it is one I built up myself over alot of years, there have been several contributors from people I know, I left them out to protect the guilty.

The script basically waits for input, any input it gets gets a datetime-stamp on the entry. Good for tracking just what the hell you were doing or writing about or thinking, I think of it as the captains log from star trek:

A neat little Perl script for listing files in the Dir and Subs from smallest to largest with a little Asterick graph

 du -k | sort -n | perl -ne 'if ( /^(\d+)\s+(.*$)/){$l=log($1+.1);$m=int($l/log(1024)); printf  ("%6.1f\t%s\t%25s  %s\n",($1/(2**(10*$m))),(("K","M","G","T","P")[$m]),"*"x (1.5*$l),$2);}'

Awebb, allow me to steal yours and modify it slightly to query translate.google.com (EN->DE)

Awebb · 2012-08-07 14:46:17

It's basically a showcase for using xdg-open in a script. You can even pass output to it with a pipe and xargs. I'm not too fond of reading from STDOUT in bash, so xargs is a must.

Hmm.. OK so what's wrong with reading from stdout?

...and what's so great about xargs? Seems a bit hacky to me. Handy for something quick in a terminal, but there's usually another way.

Machinebacon, what does -O- do?

machinebacon · 2012-08-08 20:35:13

Tuna, -O- prints directly to standard output (the second - is stdout). You could also direct into a file first (use -O) :

wget -q -O tuna.txt "http://rss.allrecipes.com/daily.aspx?hubID=80"
cat tuna.txt | grep '<title>' |  sed 's/<title>//g' | sed 's/<\/title>//g' | sed 's/Allrecipes Logo//g'

Take my script and and echo "beer" | thatscript. It won't work, because it does not produce an argument that can be passed as $1. You need xargs, to create an argument. I am not too fond, as I said, because, well, I don't know how :-D

cat <filelocation>/<filename> | curl -F 'sprunge=<-' http://sprunge.us

great way to let others see files (configs etc) (no pictures though)

mynis01 · 2012-08-22 13:07:11

Ever monitor disk read/writes with conky and wonder wtf is writing to your disk? Check out pidstat. I'm probably going to work this into conky somehow at some point.

^ Or use iotop, from package of the same name:

sudo iotop -d 2 -o

arclance · 2012-08-22 14:15:07

Or you could use ${top_io} in conky.

top_io     type num     Same as top, except sorted by the amount of I/O the process has done during the update interval

@awebb Getting stdin into a script:
*) some commands will take stdin no problem, eg cat, sed, awk or read:

read -t 1 input1 input2

will read two words from stdin or exit with error after 1 second, so you can do

read -t 1 input1 input2
[[ $input1 ]] || get_input_some_other_way

*) /dev/stdin is a file, so access it as you would a file. In your script

$query="$( < /dev/stdin )"

might work.

eg this works

cat /etc/init.d/* | leafpad /dev/stdin

to see all the init.d files at once.

-------------------------------------------------

@anyone
comm: a handy utility for comparing two lists. (see man comm)
NB the two lists have to be sorted, so you often have to pipe some output to sort and do a process substitution:

comm <( do_something | sort ) <( do_something_else | sort )

Not my own, bloom (I think he's registered here as baskerville) posted it on the arch-forums.
It takes a file as an argument and uploads it to ompldr.org, then prints the url + bbcodes to stdout and puts the latter in your clipboard. (It even has a nice progress-bar!)
If you run bash, simply change the shebang, it works.

#! /bin/dash

bbcodes=$(mktemp)
tmpout=$(mktemp)

while [ $# -gt 0 ] ; do
    if [ -t 1 ] ; then
        printf '%s \033[1;36m%s\033[0m\n' "Chomping" "$1"
    else
        echo "Chomping $1"
    fi
    curl -# -F "file1=@$1" http://ompldr.org/upload -o "$tmpout"
    if [ $? -eq 0 ] ; then
        awk '/BBCode:/ { gsub(/<[^<]*?\/?>/, ""); $1=$1; sub(/^[^:]*:/, ""); print }' "$tmpout" >> "$bbcodes"
        if [ -t 1 ] ; then
            awk '/Info:|File:|Thumbnail:|BBCode:/ { gsub(/<[^<]*?\/?>/, ""); $1=$1; sub(/^/, "\033[1;30m"); sub(/:/, "\033[0m: "); print }' "$tmpout"
        else
            awk '/Info:|File:|Thumbnail:|BBCode:/ { gsub(/<[^<]*?\/?>/, ""); $1=$1; sub(/:/, ": "); print }' "$tmpout"
        fi
    fi
    shift
done

if [ -s "$bbcodes" ] ; then
    cat "$bbcodes" | xsel -bi
fi

rm "$tmpout" "$bbcodes"

Here is what I use, very simple, nothing fancy:

#!/bin/bash

WALLPAPERS="/home/iann/downloads/wallpaper"
ALIST=( `ls -w1 $WALLPAPERS` )
RANGE=${#ALIST[@]}
let "number = $RANDOM"
let LASTNUM="`cat $WALLPAPERS/.last` + $number"
let "number = $LASTNUM % $RANGE"
echo $number > $WALLPAPERS/.last

feh --bg-scale $WALLPAPERS/${ALIST[$number]}

It uses feh to set the wallpaper, since I have that installed anyway, but you could change it to nitrogen.

^ I dislike necro posts as much as the next guy (maybe more) but I don't really think posting a new script in a script thread qualifies. There is really no dated information in this thread, and iann just added his own script.

brontosaurusrex · 2013-07-06 00:04:57

here is one called "where is my Nvidia?"

iann · 2013-07-06 00:11:13

I posted in the wrong thread anyway. So now I'm going to get in trouble for double-posting

DebianJoe · 2013-07-06 00:17:49

@pids. I would have preferred to see the script in a new thread that referenced this one. I agree, though, bash is never deprecated.
