did you ever wanted to know for shure what process is bringing up your disc led now?

Code:
alias blockdump="echo 1 > /proc/sys/vm/block_dump && tail -f /var/log/messages;  echo 0 > /proc/sys/vm/block_dump"


ctrl-c makes everything like before.

I don't think you can make aliases that use arguments unless you're using csh, you're only option is to write a function:
Code:
cdls () { cd $* && ls --color=auto }

This works in zsh and it should work in bash too.

Thanks that you moved this thread to its apropriate place (I just didnot know where to place it best)

To XENTRIC:
Nice I have adopted your clear, exit, chmod and chown aliases:)

cd fun
====

With all the 'cd' related aliases, I don't recall seeing:

# processes symbolic links first AND (best of all) tells you where you are physically, instead of logically
alias cd='cd -P'

Also, to go back to the prior folder, no mention of:

cd -

oracle fun
======
- entering sql to take user to same folder every time, great for accessing favorite sql scripts and using the same user-defined configuration every time.
- requirements:
folder in home directory called sql+
file called login.sql in sql+ directory
must have ex (vi)
following 2 aliases defined:
Code:
alias zz='echo "%s/\(set sqlprompt\).*/\1 \"SQL [${ORACLE_SID}]> \"/
%s/\(set linesize\).*/\1 `tput cols`/
wq" | ex -s ${HOME}/sql+/login.sql'
alias sql='(zz; cd ~/sql+; sqlplus /; cd -'

- login.sql must contain
Code:
set sqlprompt "SQL [any SID since this is updated by zz]> "
set linesize 135

Both these lines are updated by zz
Put in any other favorites, such as (sample):
Code:
prompt login.sql loaded
!( echo "currently in \c"; pwd)
prompt
set sqlprompt "SQL [any SID since this is updated by zz]> "
set linesize 135
set pagesize 40000
set trimspool on
set timing on
column question_name heading "Question|Name" format a8
set echo on

- notes
I use with ops$ account for instant access based on *nix login, not tested with login/password entry
- helpful shell script to save afiedt.buf in a numbered fashion, cool since you're always in the same working folder and probably want to keep those hot scripts trapped in the buffer
Code:
#! /bin/sh
# run [b]kb[/b] from command line or from sqlplus as [b]!kb[/b]

[ -f "afiedt.buf" ] || exit 1

NUM=$(ls afiedt.[0-9]* 2> /dev/null | cut -d "." -f2 | sort -rn | line)
[ -z "${NUM}" ] && NUM="0"
NUM=$(printf %03d $(expr ${NUM} + 1)
mv afiedt.buf afiedt.${NUM}

i wanted to find a way of estimating how far a certain emerge was in compiling, so i created this - any suggestions/improvements?
/usr/bin/count:
Code:
#!/bin/sh

O=`find $1 -name *.o | wc -l`
CCOUNT=`find $1 \( -name "*.c" -o -name "*.cc" -o -name "*.cpp" -o -name "*.cxx" \) -print | wc -l`


echo $O / $CCOUNT


eg count /var/tmp/portage/foo-2.4.1

Something I made up:

First part here I got in this thread I think:
Code:
i18n_purge() {
pushd . >/dev/null 2>&1

cd /usr/share/locale

for dir in `\ls --ignore=bg* --ignore=ja* --ignore=en* --ignore=ru* --ignore=de* --ignore=locale.alias --ignore=C --ignore=POSIX`
do rm -rf $dir
done

cd /usr/share/man

for dir in `\ls --ignore=bg* --ignore=ja* --ignore=en* --ignore=ru* --ignore=man*`
do rm -r $dir
done

popd >/dev/null 2>&1; echo "Done."
}


I'd like to strip out a bit more, but I don't know what I can remove and what not...

Now for the big one:

Code:
sysclean() {
echo -n "Running sysclean. First step: emerge --depclean\n\n\n"
sleep 5
echo -n "Running emerge --depclean...\n\n\n"
emerge --depclean -v

echo -n "\n\n\nSecond Step: revdep-rebuild\n\n\n"
sleep 5
echo -n "Running revdep-rebuild...\n\n\n"
revdep-rebuild

echo -n "\n\n\nThird Step: i18n_purge\n\n\n"
sleep 5
echo -n "Running i18n_purge...\n\n\n"
yes | i18n_purge

echo -n "\n\n\nFinal Step: eclean-dist -d\n\n\n"
sleep 5
echo -n "Running eclean-dist -d...\n\n\n"
eclean-dist -d

echo "\n\n\nDone. System has been cleaned.\n\n\n"
}


Bet you can't guess what that does!

The logic in the order:

Once you've run --depclean, running revdep-rebuild will (hopefully) resolve any issues before going through (and thus hopefully avoiding the hassle of a recompile) with removing locales, and the distfiles. I use i18n_purge instead of localepurge because well, it does the same thing, and does it just as well, without requiring one to run perl..

Edit: Added some additional info

for those who use screen with rtorrent:

run rtorrent as:

nice --adjustment=15 rtorrent

to save yourself some headaches when checking a hash.

It could be anything from an awesome script like unfoo, to something really useful shell utils like CTRL+C, bg, fg and jobs, or absolutely useless like "/usr/bin/yes" or "/usr/games/banner"

ctrl+s & ctrl+q

ctrl+s will freeze the console,
ctrl+q will thaw it back up.

pretty useful if you have a lot of output scroll by really fast and you need to examine something in the middle that's getting pushed outta that annoyingly small scrollback buffer too fast.

it's a terminal function... works on "real" virtual terminals on tty1 and the like, and on virtual terminals like xterm... at least those're the only ones i tried it on.

EDIT: try with a script like this one:
Code:
while sleep 1; do echo .; done

What does yes do? Just do a Y and carriage return?
