Install script for getwallpaper

install getwallpapers

#!/bin/bash
# user variable should be passed when invoking script
# this way the crontab can be installed for the appropiate user 
# while having permission to move getwallpaper to executable path
user=$1
# make directories
#mkdir ~/tmp 
if [ ! -d ~/Pictures/RWallpapers ]; then
  mkdir ~/Pictures/RWallpapers
fi

# get script and save to new tmp folder as getwallpaper
curl -o ~/getwallpaper https://gist.githubusercontent.com/kalkun/8386313/raw

# make new file getwallpapers executable
chmod +x ~/getwallpaper

# move to your path on MAC unix 
if [ -d /usr/local/bin ]; then 
  echo "moving script to /usr/local/bin"
  mv ~/getwallpaper /usr/local/bin/
elif [ -d /usr/bin ]; then
  echo "moving script to /usr/bin"
  mv ~/getwallpaper /usr/bin/
else 
 echo "Could not find a /usr/local/bin or /usr/bin folder."
 echo "Where do you want to put the script 'getwallpaper' ?"
 echo -e "\nYou can use ~ to indicate home folder as in:"
 echo "~/Desktop/"
 echo "to indicate your desktop."
 read folder
 mv ~/getwallpaper $folder
fi

# remove old script if exists:
if [ -f ~/tmp/getwallpapers ]; then
 echo "Deleting old getwallpapers script"
 rm ~/tmp/getwallpapers
 echo "deleting old getwallpapers script from crontab"
 # remove old getwallpapers call from crontab: 
 crontab -u $user -l | sed '/^.*getwallpaper.*$/d' >> tempfile
 crontab -u $user tempfile
 rm tempfile
fi

# install new crontab to execute the script every half an hour
echo "*/30  *   *   *   * 	        getwallpaper" >> tempfile

echo "installing crontab for $user"
crontab -u $user tempfile

# crontab is installed - remove tempfile
echo "cleaning up"
rm tempfile
rm tmp_install

Install wallpaper

To install just copy+paste the following code into your terminal:

curl -o tmp_install https://gist.githubusercontent.com/kalkun/8943594/raw; user=$USER; chmod +x tmp_install; sudo ./tmp_install $user;

That's it now the getwallpaper script is saved and scheduled to run every half an hour.

Syntax

Any subreddit can be targeted to fetch a wallpaper sorted in anyway that reddit provides with the following syntax:

    getwallpaper [subreddit [new/rising/controversial/hour/day/week/month/year/all]]

Both arguments are optional, if no arguments are passed then a wallpaper is fetched from r/wallpapers sorted by hot. If one argument is provided then that subreddit is targeted sorted by hot.

Example

The following will fetch a wallpaper from r/art sorted by new:

   getwallpaper art new

This example sets the wallpaper after what is hot on r/earthporn:

   getwallpaper earthporn

Settings

Scheduling

The script is by default set to run every half an hour, fetching a wallpaper from r/wallpapers.
This can be changed by editing the crontab in the following way.
To open your crontable with the scheduled cronjobs in editor mode:

   crontab -e

Then change the line that includes the getwallpaper script. Either to include the arguments you prefer, or to prevent the automatic setting of a new wallpaper, you may simply delete the line or insert an '#' in front of the line to uncomment it.

Log file

By default a log file is enabled this can be changed by setting the 'log' variable on line 29 to 'false'. The log file is saved to ~/tmp/log by default, this location can be changed by changing the 'logfile' variable.
To view the logfile type:

   cat ~/tmp/log

That's it :)
