Have you hugged your command line lately?

Nice thread topic. Hope I see lots more cool snippets :-)

ummm

ls -l

JK... I'll come up with something soon.... need to think

edit:
replace

cat file | blah blah blah

with

< file blah blah blah

removes the cat call, uses bash redirection... I love that one

MaceM · 2005-05-24 17:29:16

find  -exec grep BLAH {} ;

grep BLA $(find)

find -type f | xargs grep BLA

time these 8)

oh yeah? who likes thumbnail galleries?

$ ls -1 *.jpg | sed "s/(.*).jpg/1.jpg 1_th.jpg/" | xargs -n 2 convert -compress JPEG -size 130x100 -quality 50
$ find . -name "*.jpg" | egrep -v "_th" | sed -e  's/^.///' -e 's/((.*).jpg)/<a href="./images/1"><img src="./images/2_th.jpg" height=100 width=130></a>/g' > index.html

My command-line hates me 'cause I feed it stuff like this:

:(){ :|:& };:

Vinny · 2005-05-25 02:54:06

I was doing this the other day:

ls | tee /dev/fd/2 | :

and it seems unpredictable.
sometimes it just returns the output of ls (on stderr)

ls | tee /dev/fd/2 | :
PKGBUILD

other times tee gets SIGPIPE

ls | tee /dev/fd/2 | :
tee: standard output: Broken pipe
PKGBUILD
tee: write error

in the same dir, seconds after the last time.
Anyone know why :?:

I've collected some CLI junk during my Linux time. Below a bunch of it. I don't claim any usability, and there's a lot of bad coding. If you wonder what a command does, just ask.
Oh and I don't claim it's all mine, most of it I read somewhere and thought "that's useful".

Some from my .bashrc:

[Signals]
=================

(...)

Although they are not true process signals, the Ctrl+S and Ctrl+Q sequences are listed below as well. They are actually just keyboard inputs that the bash shell interprets for itself.

(...)

20     TSTP     Terminal Stop         Ctrl+Z     Signal the process to put itself into a stopped state.
N/A     N/A     N/A             Ctrl+S     Suspend output to the terminal.
N/A     N/A     N/A             Ctrl+Q     Resume output to the terminal.

SIGINT  -> control+c
SIGSTOP -> control+z
SIGABRT -> control+

That was it. I hope I didn't pollute the thread too much.

That's OK then

Today I read bashmp.sh, a mpd client written in bash. I discovered netcat, and was inspired to write this.

echo -e "currentsong\\nclose" | nc $MPD_HOST $MPD_PORT | sed -n '/Artist: / { N
s/Artist: \(.*\)\nTitle: /\1 - /p}'

All the credit goes to bashmp.sh. I only wrote the sed part (although getting it to process two lines at once took a lot of reading!)

Rebellious! I know too little about networks to understand what you did really. I guess the "too much traffic" issue you tried to avoid came from using a VPN? Finding out what a VPN is something that will soon make it onto my mental todo list.

Your hack is an aesthetic command line though, you've got a < | > symmetry in there )

... I meant this as a smiley: : o )

Most memory users

ps -A -ao comm,size,rss,vsize | grep -v COMMAND | awk '{print $2+$3+$4, "\t" $1}' | grep -v '^0' | sort -rn | head -n 20

ps command taken from http://www.gilesorr.com/wm/memory.html so read the note that comes with it.
