Re: Post your handy self made command line utilities

A script I just wrote to refresh pacman's mirrorlist when I see it's out of date.

#!/bin/bash

if [[ ${UID} -ne 0 ]] ; then
	echo "You must be root to update pacman's mirrorlist."
	exit 1
fi

(curl -s "https://www.archlinux.org/mirrorlist/?country=all&protocol=ftp&ip_version=4&use_mirror_status=on" | \
sed s/#Server/Server/g) > /etc/pacman.d/mirrorlist
pacman -Syy

Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity.
What profit hath a man of all his labour which he taketh under the sun?
All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

Re: Post your handy self made command line utilities

Made this to manage my university website with Markdown.

#!/bin/bash
#
#  Copies over files from a directory with markdown files
#  (ending with .md) transformed into HTML files. The
#  generated HTML files are prepended and appended
#  respectively with .pre.html and .post.html from the
#  source directory. TITLE in .pre.html is swapped with the
#  first line in the markdown file. 
#
#  This script requires a markdown implementation such as
#  discount.
#
#     http://www.pell.portland.or.us/~orc/Code/discount/
#  

function usage {
   echo 'Usage: makeweb.sh <source-directory> <destination-directory>'
}

function gettitle {
   title=$(head -n 1 $1 | sed 's/^\s*#*\s*//')
   if ! [ -n "$title" ]; then
      echo 'Untitled'
   else
      echo $title
   fi
}

if ! [ -n "$1" -a -n "$2" ]; then
   usage
   exit 1
fi

if ! [ -d $1 -a -d $2 ]; then
   usage
   exit 1
fi

srcdir=$(cd $1 && pwd)
destdir=$(cd $2 && pwd)

if ! [ -f $srcdir/.pre.html ]; then
   echo 'No .pre.html file in source directory!'
   exit 1
fi

if ! [ -f $srcdir/.post.html ]; then
   echo 'No .post.html file in source directory!'
   exit 1
fi

echo "$srcdir -> $destdir"
cd $srcdir

for src in $(find -type f); do
   if basename $src|egrep '.md$'; then
      dest=$destdir/$(echo $src|sed 's/md$/html/')
      cat $srcdir/.pre.html | sed "s/TITLE/$(gettitle $src)/" > $dest
      markdown -f html $src >> $dest

Re: Post your handy self made command line utilities

This script toggles several screensaver/power-saving features.
Be sure to put something like 

sed -i s/^SCREENSAVER.*/SCREENSAVER="on"/ $HOME/.screentoggle

in your startup script/.xinitrc.

#!/bin/bash

SCREENSAVER=on

case "$SCREENSAVER" in
	on)
	   xset s off
	   xset -dpms
	   setterm -blank 0 -powerdown 0
	   sed -i s/^SCREENSAVER.*/SCREENSAVER="off"/ $0
	   # Example Notification: twmnc -t "Screensaver:" -c "off" -l twmn-screen.conf
	   ;;
	off)
	   xset s on
	   xset +dpms
	   setterm -blank 20 -powerdown 30

Re: Post your handy self made command line utilities

As a relative newcomer to Arch, I am discovering the great satisfaction gained from writing small bash scripts to automate a job that would normally take a bit more manual labour. I thought I'd start a thread here where people can share their own scripts that save those few precious seconds by automating the mundane.

Here's one I use quite frequently. Very simple, no magic. It checks if my Virtual machines are online, if so, prompts me to close them, kills them, then upgrades my packages and rebuilds VirtualBox's kernel modules. After that, it checks to see if pacman has made a new rc.conf and if so will open them up side by side for comparison before removing the .pacnew version.

#! /bin/bash

#************************************************
#                    Syu.sh                      
#                  Nov 14, 2011                  
#                                                
#   System upgrade and reconfiguration script.   
#************************************************

function config ()
{
   # Kill VirtualBox.
    if ps ax | grep -v grep | grep VirtualBox > /dev/null
    then
        echo "Shut down all virtual machines then press Enter."
        read
        pkill VirtualBox
    fi

    pacman -Syu

    # Rebuild vbox kernel modules.
    sudo vboxbuild
    sudo modprobe vboxdrv
}

function check_root () 
{
    ROOT_UID=0
    EXIT_NOTROOT=87
    if [ "$UID" != "$ROOT_UID" ]
    then
    echo "Must be run as root."
    exit $EXIT_NOTROOT
    fi
}

function pacnew ()
{
    echo "New rc.conf available. Edit [y/n]?"
    read in
    if [ "$in" == y -o "$in" == Y ]
    then
        pacnew_edit
    fi
    if [ "$in" == n -o "$in" == N ]
    then
        end
    fi
    pacnew
}

function pacnew_edit ()
{
    meld /etc/rc.conf /etc/rc.conf.pacnew
    echo "Remove rc.conf.pacnew?"
    read in
    if [ $in == y -o $in == Y ]
    then
        rm /etc/rc.conf.pacnew
        echo "/etc/rc.conf.pacnew removed..."
    fi
    end
}

function end ()
{
    echo "System update complete."
    exit 0
}

check_root
config
echo ""
if [ -e /etc/rc.conf.pacnew ]
then
    pacnew
fi
end

Re: Post your handy self made command line utilities

I made a little script that is a wrapper for Imagemagick, Tesseract, hocr2pdf, and Ghostscript.

Essentially, I convert a color-scanned image to black-and-white TIF (I found that OCR is better this way and it doesn't seem to slow the process down too much), apply OCR to that file, then combine the OCR data with the color image to be a color OCR PDF.  It'll do this for all the JPGs in a directory, then combine the resulting PDFs into one multipage PDF and delete all the temporary working files.

It accepts a directory as an argument.

for file in $@*.jpg
    do
        echo 'Converting '${file}' to TIF format for OCR...'
        convert ${file} -normalize -colorspace gray -colors 2 +dither -type bilevel ${file%*.jpg}.tif
        echo 'Converting '${file%*.jpg}'.tif to hOCR format...'
        tesseract ${file%*.jpg}.tif ${file%*.jpg} nobatch hocr
        echo 'Combining hOCR with image data to produce output PDF...'
        hocr2pdf -i ${file} -o ${file%*.jpg}.pdf < ${file%*.jpg}.html
    done

echo 'Combining PDF documents...'
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=$@Combined-OCR.pdf $@*.pdf

echo 'Cleaning up '$@'...'
for file in $@*.jpg
    do
        rm ${file%*.jpg}.pdf &
        rm ${file%*.jpg}.html &
        rm ${file%*.jpg}.tif
    done

This is my first bash script so some of the syntax and the like is probably sloppy.

Re: Post your handy self made command line utilities

Been fooling around with a script to parse syslinux's config and easily load kernels via kexec:

#!/bin/bash
#
# kload - a syslinux.cfg parser for autoloading a kernel for kexec
#

bootloadercfg=/boot/syslinux/syslinux.cfg

error() {
  local mesg=$1; shift
  printf "==> ERROR: $mesg\n" "$@"
} >&2

die() {
  error "$@"
  exit 1
}

usage() {
  cat <<EOF
usage: ${0##*/} <label> [rootoptions]

${0##*/} parses syslinux's bootloader configuration and automates the process
of loading a new kernel for kexec. If specified, any root options will override
the APPEND line of the config for a given kernel.

  Options:
    -f <file>   use another config file (default: /boot/syslinux/syslinux.cfg)
    -h          display this help message.
    -l          display available kernels by label

EOF
  exit 1

    function longest(list,       listlen,i, len, maxlen) {

Re: Post your handy self made command line utilities

Well fairly new to arch, used linux before however never really took to bash and then recently got back into it, due to arch's nature things are alot easier with a little bash. This is one of my first bash scripts.

Here is my script 'pacaur.sh' which installs a package if given the AUR tarball address. It uses a directory as a home in which it makes the package, so before use make the dir pacaur/

Usage: ./pacaur.sh http://aur.archlinux.org/packages/ar/ar … hey.tar.gz
*used archey for example*

#!/bin/bash

#variables
PACAUR_HOME=$HOME"/pacaur"
PACKAGE_URL=$1

init() {
    cd $PACAUR_HOME
    rm -rf *
}

getpackage() {
    wget -q $PACKAGE_URL
}

makepackage() {
    tar -zxf $(ls *.tar.gz | cut -d ' ' -f1 | head -n1)
    cd $(ls -d */ | cut -d ' ' -f1 | head -n1)
    makepkg -s
    sudo pacman -U $(ls *.tar.xz | cut -d ' ' -f1 | head -n1)
}

init
getpackage
makepackage

comments/criticism and suggestions are welcome and appreciated big_smile

Re: Post your handy self made command line utilities

@warb0
Any reason why you don't figure out the download url for the user?

tar -zxf $(ls *.tar.gz | cut -d ' ' -f1 | head -n1)

Why? The directory has just one file, the one you downloaded, so ..??

sudo pacman -U $(ls *.tar.xz | cut -d ' ' -f1 | head -n1)

Why not e.g.  'sudo pacman -U *.tar.xz'? You can skip it altogether if you use 'makepkg -si'.


Using the output of 'ls' like this is bad practice. Read bash manual and some other resources https://wiki.archlinux.org/index.php/Le … sh.2FShell

Thanks for your input, as I said this is pretty much one of my first bash script other than basic things, I will take this into account, and probably submit a newer version at some point, however I see your point, some of my code here seems redundant. Also can you please explain how you would go about getting the url for the user? I'm assuming something along the lines of a wget/lynx --dump then cat/grepping the file for the url? Is there a better way for this?

URLs follow a standard format. Assuming $1 is whatever you're passing into the script or function, it'd look like:

http://aur.archlinux.org/${1:0:2}/$1/$1.tar.gz

Technically, you shouldn't rely on this -- you should be using the RPC interface to the AUR which returns json (and looking at the URLPath element in the reply object).

Ignoring the RPC, you could write something naive such as:

#!/bin/bash

if curl -s "https://aur.archlinux.org/${1:0:2}/$1/$1.tar.gz" | bsdtar xz - 2>/dev/null; then
  cd "$1" || { echo "error: failed to chdir to $1"; exit 1; }
else
  echo "error: $1 not found"
  exit 1

Re: Post your handy self made command line utilities

Ah, I simply didn't want a fully-featured package manager for AUR, with little need, as most of the things I use come from official repos. I've added features to that script, but later removed them because it felt like unneeded bloat.

Nothing wrong with Yaourt, just personal preference.

Re: Post your handy self made command line utilities

This is a little script I use to get a clearly arranged list of my mountpoints:

# Set header
header="<filesystem> <dir> <type> <options> <label>"

# Get all mountpoints
mounts_all=$(mount -l | tr -d "()[]" |awk '{print $1,$3,$5,$6,$7}')
# Get only virtual mountpoints
mounts_virt=$(echo  "${mounts_all}" |sed '/^\//d' |sort)
# Get only real mountpoints
mounts_real=$(echo  "${mounts_all}" |sed '/^[[:alnum:]]/d' |sort)


if [[ ${1} == "--full" ]] || [[ ${1} == "-f" ]]; then
	echo -e "${header}\n${mounts_virt}\n${mounts_real}" | column -t
else
	echo -e "${header}\n${mounts_real}" |column -t
fi

Example output:

<filesystem>  <dir>  <type>  <options>                 <label>
/dev/sda1     /boot  ext2    rw                        boot
/dev/sda3     /      ext4    rw,commit=0               root
/dev/sda5     /var   ext4    rw,commit=0               var
/dev/sda6     /tmp   ext4    rw,nosuid,nodev,commit=0  tmp
/dev/sda7     /home  ext4    rw,commit=0               home

You should take a look at findmnt.

Ah. Didn't know about it.
I am not able to get it to show any Labels. Besides the selection of real mountpoints is much easier in my script.
But still thanks for the information.

Configures an external monitor connected over VGA.

#!/bin/bash
mode="$(xrandr -q|grep -A1 "VGA1 connected"| tail -1 |awk '{ print $1 }')"
if [ -n "$mode" ]; then
    xrandr --output VGA1 --mode "$mode" --right-of LVDS1
    xrandr --output LVDS1 --primary
else
    xrandr --output VGA1 --off
fi
