[ILUG] more handy tips...

[John P . Looney]

 Thought I'd post a few more handy little tips, in the hope people would
post theirs:

 I've included something for your ~/.bashrc or ~/.kshrc - it's a simple
unarc shell function, so that you can do stuff like:

 $ cd ~/unarc
 $ unarc ~/thing.zip ~/linux-2.2.12.tar.gz
 Unarchiving pkzipped file thing.zip ...
 Unarchiving gzipped file linux-2.2.12.tar.gz
 Done in 34 seconds.
 $

 Here is my prompt (view it: http://www.RedBrick.dcu.ie/~valen/kates.gif).
It's got pretty colours, based loosely on the rasterman's one, and prints
the username, hostname, and directory into the titlebar of your terminal.
The important bit, I suppose is that you can use the following escape code
to set a terminals' titlebar:

 ^[]2; title ^G

 So, it's escape, end-square-bracket, the numeral two, a semi-colon, and
then the text you want in the titlebar. To return to the terminal itself,
end with a control-G character. Easy!

 Get annoyed with all the different audio formats around ? 

# ln -s /dev/audio /dev/audio.au

 Now, to play *any* sample:

$ sox sample.wac /dev/audio.au 

 Sorted :)

 Now, some source:

# The source of the unarc shell function:
unarc () {
   START=$SECONDS
   for i in $*
     do
        if [ "`echo $i | grep bz2`" != "" ] ; then
            echo Unarchiving bzipped tarfile $i...
            nice bzip2 -dc $i | tar xf -  2>&1
        elif [ "`echo $i | grep zip`" != "" ] ; then
            echo Unarchiving pkzipped file $i...
            nice unzip -q $i  2>&1
        elif [ "`echo $i | grep tar.gz`" != "" ] ; then
            echo Unarchiving gzipped tarfile $i...
            nice gzip -dc $i | tar xf -  2>&1
        elif [ "`echo $i | grep tgz`" != "" ] ; then
            echo Unarchiving gzipped tarfile $i...
            nice gzip -dc $i | tar xf -  2>&1
        elif [ "`echo $i | grep tar.Z`" != "" ] ; then
            echo Unarchiving gzipped tarfile $i...
            nice gzip -dc $i | tar xf -  2>&1
        else
            echo Unarchiving tarfile $i...
            nice tar xf $i`
        fi
     done
    echo Done in `expr $SECONDS - $START` seconds.
} # end unarc

The source for my prompt:

  GRAD1='\333\262\261\260'
  GRAD2='\260\261\262\333'
  YLOBRN='\033[01;33;43m'
  WHTBRN='\033[01;37;43m'
  REDBRN='\033[00;31;43m'
  REDBLK='\033[00;31;40m'
  BLKRED='\033[00;37;41m'
  PPLBLK='\033[01;35;40m'
  WHTBLK='\033[01;37;40m'
  NONE='\033[00m'
  E='\['
  R='\]'
  PS1='^[]2; \u on \h in \w ^G'${E}${WHTBRN}' '${R}${E}${REDBRN}${GRAD2}${BLKRED}' \u : \h : \w/ '${REDBLK}${GRAD1}${WHTBLK}${R}' \d \t '${E}${NONE}' \n'${PPLBLK}${R}'\h ['${?}'] '${E}${NONE}${R}' '

 Anyone else want to post some convienence stuff to the list ?
