Re: Post your handy self made command line utilities

Some utilities for mounting stuff.

alias mta='sudo mount -a'
alias umta='sudo umount -a'
mt() {
    if [ ! -e /media/$1 ]; then
        sudo mkdir /media/$1
    fi
    sudo mount LABEL=$1 /media/$1
}
umt() {
    sudo umount /media/$1

yeah, all the sites i've seen mention both methods as being valid (dunno about your whole 'less weird' comment... wink); i could've been typoing something, but one time i remember i had to resort to the 2>&1 at the end to get tcprobe or vobcopy to stop spitting shit to screen when i was redirecting to a file, thereafter i just 'defaulted' myself to that way.

This to .bashrc. If no arguments given, it shows what daemon scripts you have in /etc/rd.d/ and running daemons and as you can see it starts, stops and restarts daemons.

Re: Post your handy self made command line utilities

hi ak-89,

Here is the function I'm using as well as the bash completion file I use:

# grep service .bashrc 
service () { /etc/rc.d/$1 $2 ; }     #alias 'service' to /etc/rc.d
# cat /etc/bash_completion.d/service 
_service_complete()
{
  local cur prev

  COMPREPLY=()
  cur=${COMP_WORDS[COMP_CWORD]}
  prev=${COMP_WORDS[COMP_CWORD-1]}

  if [ "$prev" == service ]; then
    COMPREPLY=( $(compgen -W "\
      $(  for service in /etc/rc.d/*; do
            echo ${service##*/}
          done )" -- $cur ) )
  else
    COMPREPLY=( $(compgen -W '\
      start
      stop
      restart
      reload' -- $cur ) )
  fi
}

Re: Post your handy self made command line utilities

Here's how I connect to my netcfg profiles in wmii.

#!/bin/bash
# wmii netcfg manager

# get current wmii color scheme
wmiictl='wmiir read ctl' 
font=`$wmiictl | grep font | sed 's/font //'`
norm=`$wmiictl | grep norm | sed 's/normcolors //'`
sel=`$wmiictl | grep focus | sed 's/focuscolors //'`
norm_bgcolors=`echo $norm | cut -d ' ' -f 2`
sel_bgcolors=`echo $sel | cut -d ' ' -f 2`
norm_fgcolors=`echo $norm | cut -d ' ' -f 1`
sel_fgcolors=`echo $sel | cut -d ' ' -f 1`

# get configured profiles
profiles=`ls /etc/network.d/ -1Ap \
    | grep -v /\$` 

# additional dmenu options can be set here
choice=`echo "$profiles" | dmenu -i -b \
    -fn "$font" \
    -nf "$norm_fgcolors" \
    -nb "$norm_bgcolors" \
    -sf "$sel_fgcolors" \
    -sb "$sel_bgcolors"`

# make sure the selection exists
for i in $profiles; do
    if [[ $choice = $i ]]; then 
        sudo netcfg -a 
        sudo netcfg $choice
    fi
done

This is my first 3< line  bash script, so I welcome suggestions to improve it!

Small function to install stuff from ABS.

        echo "Usage: absi <repo> <pkg>"
        return 1

}

Re: Post your handy self made command line utilities

A little script to start/stop httpd and mysqld, and optionally open/close port 80 if you're using firehol, plus update your DynDNS IP. I use it when I do web development locally. The part that opens port 80 assumes that you have a commented "server http accept" in /etc/firehol/firehol.conf

#!/bin/bash

. /etc/rc.conf
. /etc/rc.d/functions

DYNDNS=1  # Use DynDNS?
FIREHOL=1 # Use firehol?

case "$1" in
    start|restart)
        if [ $DYNDNS -eq 1 ]; then
            stat_busy "Updating DynDNS IP"
            dyndns.sh > /dev/null 2>&1
            stat_done #TODO: check if update was succesful
        fi
        if [ $FIREHOL -eq 1 ]; then
            stat_busy "Opening HTTP port"
            sed -e 's/^[ \t]*#[ \t]*server http accept/\    server http accept/' /etc/firehol/firehol.conf > /tmp/firehol.conf
            mv /tmp/firehol.conf /etc/firehol/firehol.conf
            /etc/rc.d/firehol start > /dev/null 2>&1
            stat_done
        fi
        ;;
    stop)
        if [ $DYNDNS -eq 1 ]; then
            stat_busy "Updating DynDNS IP to 127.0.0.1"
            dyndns.sh 127.0.0.1 > /dev/null 2>&1
            stat_done
        fi
        if [ $FIREHOL -eq 1 ]; then
            stat_busy "Closing HTTP port"
            sed -e 's/^[ \t]*server http accept/\    # server http accept/' /etc/firehol/firehol.conf > /tmp/firehol.conf
            mv /tmp/firehol.conf /etc/firehol/firehol.conf
            /etc/rc.d/firehol start > /dev/null 2>&1
            stat_done
        fi
        ;;
    *)
        echo "Usage: $0 {start|restart|stop}"
        exit 1;
        ;;
esac

/etc/rc.d/httpd $1
/etc/rc.d/mysqld $1

And the dyndns.sh used (most of it isn't mine, but I can't seem to find the original source). It has to be in your $PATH

#!/bin/sh
# This script uses "dyndnsupdate" available at http://www.bebits.com/app/2927

HOSTNAME=DYNDNS_HOSTNAME
NSLOOKUP=`/usr/bin/nslookup -sil $HOSTNAME | tail -2 | head -1 | cut -d" " -f2`

case "$1" in
    '')
        CURRENT_IP=`/usr/bin/lynx -dump http://www.netins.net/dialup/tools/my_ip.shtml | grep -A2 "Your current IP Address is:" | tail -n1 | tr -d ' '`
        if [ "$CURRENT_IP" = "unknown" ] ; then
            exit
        fi
        ;;
    *)
        CURRENT_IP=$1
        ;;
esac

# Is our current IP in the DynDNS DNS records? If not, update them.
if [ "$NSLOOKUP" != "$CURRENT_IP" ] ; then
   /sbin/dyndnsupdate -a $CURRENT_IP -h $HOSTNAME -m \
   $HOSTNAME\'s_mail_exchange.dyndns.org -s statdns \

Re: Post your handy self made command line utilities

Based on a script I saw somewhere, but never read, perhaps even in this thread, but entirely original code.

I know it probably isn't the most efficient way of going about it, but I'm still learning, and for all means and purposes, it works for me.

EDIT: Updated

First script saves the currently playing track to a list, second one selects a random track from that list and plays it.

It will probably break if your list contains one entry, and you try and invoke the second script while listening to that track (eval `$0` loop)

#!/bin/sh

gtrack=$(mpc | head -1)

if [ -e $HOME/.gslist ]
then
        touch $HOME/.gslist
fi

if [ "$(cat "$HOME/.gslist" | grep "^$gtrack$")" != "$gtrack" ]
then
        echo $gtrack >> $HOME/.gslist
        echo -e "Track added to gslist\007"
else
        echo -en "ERROR: Track is present in gslist\007"
        sleep 0.2
        echo -e "\007"
fi
#!/bin/sh

if [ -e "$HOME/.gslist" ]
then
        gline=$(wc -l "$HOME/.gslist" | awk '{print $1}')
        rand=$[ ( $RANDOM % $gline ) + 1 ]
        line=$(awk "FNR == $rand" "$HOME/.gslist")
        if [ "$line" != "$(mpc | head -1)" ]
        then
                num=$(mpc playlist | grep "$line" | awk '{print $1}' | sed 's/ |)//')
                mpc play $num
        else
                eval `$0`
        fi
else
        echo "ERROR: $HOME/.gslist is not present, add some songs"
fi

Re: Post your handy self made command line utilities

I wrote a weather script in Lua for my Conky. It's pretty much the first real script I've written in Lua, but it works well. The Lua version of this script can run in about .150 seconds, while a nearly identical Python version takes .250-.300. It uses Yahoo's weather API since it's not sending as much downstream and the RSS feed is easy to parse with a pattern. (Requires LuaSocket.)

#!/usr/bin/env lua
-- Lua weather downloader
-- Gets info from Yahoo! Weather API

require 'socket.http'

baseurl = 'http://weather.yahooapis.com/forecastrss?u=XYZ&p='

if #arg < 1 then
    print("Please specify a ZIP code or Yahoo location ID")
    os.exit(1)
end

zipcode = arg[1]

if #arg > 1 then
    if string.lower(arg[2]) == 'f' or string.lower(arg[2]) == 'c' then
        units = string.lower(arg[2])
    else
        units = 'f'
    end
else
    units = 'f'
end

pattern = [=[<yweather:condition%s+text=['"]([%s%w]+)['"].+temp=['"](%d+)['"]]=]

url = string.gsub(baseurl, 'XYZ', units) .. zipcode

weatherdata = socket.http.request(url)

condition, temp = string.match(weatherdata, pattern)

print(condition .. ", " .. tostring(temp) .. string.upper(units))

Thanks,

Re: Post your handy self made command line utilities

so, i found myself in need of a few awk printf strings this week.  i decided to write a little script to a) reinforce the syntax and b) quickly remind me when i need one of these awk lines some time in the future.  i hope to add more as i need/learn them.

NOTE: what's below is NOT the script; it is the script's output. wink

┌─[ 22:58 ][ blue:~ ]

from man 7z::

DO NOT USE the 7-zip format for backup purpose on Linux/Unix because :
        - 7-zip does not store the owner/group of the file.

       On Linux/Unix, in order to backup directories you must use tar :
        - to backup a directory  : tar cf - directory | 7za a -si directory.tar.7z
        - to restore your backup : 7za x -so directory.tar.7z | tar xf -

Re: Post your handy self made command line utilities

lolilolicon, i actually would've expected that to happen on overflow with one of the N.Ns's but as you can see it didn't, and i'm afraid the man pages are a bit greek to me...

maybe when you find out you can let me know so i can add it smile

Re: Post your handy self made command line utilities

I was expecting that too... strange. I think Procyon will come and tell us how to do that :-)

This to .bashrc. If no arguments given, it shows what daemon scripts you have in /etc/rd.d/ and running daemons and as you can see it starts, stops and restarts daemons.

Oh hoo!  Very nice.

substr can do that:
$ echo 123456 1234567890123456789 | awk '{printf "| %-10.10s | %-10.10s |", $1, substr($2,length($2)-9)}'

Re: Post your handy self made command line utilities

#!/bin/bash
test "$(whoami)" != "root" && {
    echo "Must be run as root."
    exit 1
}
bckdir=/media/Arch_Backups
bcknm="arch-$(date +'%d.%m.%y')"
echo "Backing up system..."
if ! mountpoint -q "$bckdir"; then
    echo "\"$bckdir\" not mounted."
    exit 1
elif test -e "$bckdir/$bcknm"; then
    echo "\"$bckdir/$bcknm\" already exists."
    exit 1
fi
cp -avx / "$bckdir/$bcknm"

Random little backup script I wrote a week or two ago. It'll only work if the destination directory is a mounted drive, due to some cp limitation or other.

Umm, I don't think I get it. If you want to backup everything (/dev? /proc?) and copy it to f.e. /home/backup, which itself will be also backed up to /home/backup ... 'cp -x' means "stay on this file system" so if you mount the bckdir it won't get copied in the loop-like fashion (haven't tested it, but that's what I infer from man pages).

Re: Post your handy self made command line utilities

You can't copy a directory into a subdirectory of itself unless the subdirectory is mounted. Allow me to show you what I mean:

peasantoid # cp -avx / /media/backups/arch-31.05.09
`/' -> `/media/backups/arch-31.05.09'
`/media' -> `/media/backups/arch-31.05.09/media'
`/media/cd' -> `/media/backups/arch-31.05.09/media/cd'
`/media/.hal-mtab' -> `/media/backups/arch-31.05.09/media/.hal-mtab'
`/media/dvd' -> `/media/backups/arch-31.05.09/media/dvd'
`/media/backups' -> `/media/backups/arch-31.05.09/media/backups'
cp: cannot copy a directory, `/', into itself, `/media/backups/arch-31.05.09'

(In this example, /media/backups is not mounted.)
