Fixing a Broken yaourt and pacman on Arch linux, building package

My Arch system was not updated for quiet a while, the package manager was giving me trouble and failing.

Then i proceeded to recompile my yaourt package installer from scratch.
Here's how I went about my  job..

Note: Do not elevate to root user

wiz@Arch-DOC:~$ git clone https://aur.archlinux.org/yaourt.git

wiz@Arch-DOC:~$ cd yaourt/
wiz@Arch-DOC:~/yaourt$ ls
PKGBUILD
wiz@Arch-DOC:~/yaourt$ pwd
/home/wiz/yaourt


Now go on to building the package:

See some output for yourself..

Thus I completed rebuilding the yaourt and was able to fix the package manager

enable synaptics tapping on Gnome in Archlinux

Before proceeding with tweaking the touchpad, lets search for touchpad packages are available for us in the repository..

wiz@Arch-DOC:~$ sudo pacman -Ss touchpad
extra/xf86-input-synaptics 1.8.1-1 (xorg-drivers xorg) [installed]
    Synaptics driver for notebook touchpads
community/gpointing-device-settings 1.5.1-5
    GUI tool for setting pointing device such as TrackPoint or Touchpad
community/kcm-touchpad 1.1-1
    KCM, daemon and applet for touchpad
community/libsynaptics 0.14.6c-6
    Library for accessing synaptics touchpads


Im on Gnome and my touch pad doesn't seem to do what I intend it to behave,
Now it took quiet a bit of time finding the corresponding packages..
Lets fetch and install the gpointing-device-settings

wiz@Arch-DOC:~$ sudo pacman -S community/gpointing-device-settings

Some cool tricks with AWK and CUT

This following script prints out the sum of the disk utilization of total directories

[root@Arch-DOC ~]# du -sh /home/wiz/
184G    /home/wiz

[root@Arch-DOC ~]# du -sh /home/wiz/* | egrep  '[0-9]G'
2.5G    /home/wiz/Docs
6.9G    /home/wiz/Documents
19G    /home/wiz/Downloads
19G    /home/wiz/ISO IMAGES
5.3G    /home/wiz/Music
59G    /home/wiz/r-drive
45G    /home/wiz/Videos
18G    /home/wiz/VirtualBox VMs

[root@Arch-DOC ~]# du -sh /home/wiz/* | egrep  '[0-9]G'  | awk '{print $1}' | cut -d'G' -f1| awk '{sum+=$1} END {print sum}'
174.7

Thus we can find the sum of the spaces of each individual directory utilization.

Renaming multiple files with extensions

Simple for loop is described as follows to bulk renaming files

[root@Arch-DOC test]# touch {a..z}

[root@Arch-DOC test]# for i in *; do mv $i $i.txt; done

a.txt  c.txt  e.txt  g.txt  i.txt  k.txt  m.txt  o.txt  q.txt  s.txt  u.txt  w.txt  y.txt
b.txt  d.txt  f.txt  h.txt  j.txt  l.txt  n.txt  p.txt  r.txt  t.txt  v.txt  x.txt  z.txt

[root@Arch-DOC test]# for i in *.txt; do sh -c "mv $i `echo $i| cut -d'.' -f1 `" ; done

[root@Arch-DOC test]# ls

a  b  c  d  e  f  g  h  i  j  k  l  m  n  o  p  q  r  s  t  u  v  w  x  y  z

[root@Arch-DOC test]# for i in *; do sh -c "mv $i `echo $i| cut -d'.' -f1`.pdf" ; done

[root@Arch-DOC test]# ls

a.pdf  c.pdf  e.pdf  g.pdf  i.pdf  k.pdf  m.pdf  o.pdf  q.pdf  s.pdf  u.pdf  w.pdf  y.pdf
b.pdf  d.pdf  f.pdf  h.pdf  j.pdf  l.pdf  n.pdf  p.pdf  r.pdf  t.pdf  v.pdf  x.pdf  z.pdf

Finding the list of Directories Recursively on your Linux Machine.

First of Lets create some directories..

[root@Arch-DOC test]# mkdir Dir{1..10}

[root@Arch-DOC test]# mkdir Dir1/dir1{a..z}
[root@Arch-DOC test]# mkdir Dir2/dir2{a..z}

Now we shall also create some more sub-directories under dir2.
[root@Arch-DOC test]# mkdir Dir2/dir2a/sub-sub-dir2a{1..10}

and also lets create some sample files..

[root@Arch-DOC test]# touch files{1..10}

Lets see what we have got..

[root@Arch-DOC test]# ls
Dir1  Dir10  Dir2  Dir3  Dir4  Dir5  Dir6  Dir7  Dir8  Dir9  files1  files10  files2  files3  files4  files5  files6  files7  files8  files9

Now that the directories and Sub-directories have been created. Lets run some commands to test it out.

[root@Arch-DOC test]# find ./ -maxdepth 1 -type d
./
./Dir7
./Dir9
./Dir8
./Dir4
./Dir5
./Dir2
./Dir10
./Dir1
./Dir3
./Dir6

[root@Arch-DOC test]#  ls -d */
Dir1/  Dir10/  Dir2/  Dir3/  Dir4/  Dir5/  Dir6/  Dir7/  Dir8/  Dir9/

Similarly, we can go on to the next level directories and get a list of only that particular sib directories.

[root@Arch-DOC test]#  ls -d */*/*
Dir2/dir2a/sub-sub-dir2a1   Dir2/dir2a/sub-sub-dir2a2  Dir2/dir2a/sub-sub-dir2a4  Dir2/dir2a/sub-sub-dir2a6  Dir2/dir2a/sub-sub-dir2a8
Dir2/dir2a/sub-sub-dir2a10  Dir2/dir2a/sub-sub-dir2a3  Dir2/dir2a/sub-sub-dir2a5  Dir2/dir2a/sub-sub-dir2a7  Dir2/dir2a/sub-sub-dir2a9

[root@Arch-DOC test]# find ./ -maxdepth 3 -type d | wc
     73      73    1031

Using Stream-editor and replacing the : with null value on each directory while printing to stdout.
[root@Arch-DOC test]# ls -R | grep ":" | sed -e s/://g | wc
     73      73    1030

Setingup Wifi on ArchLinux.

Before proceeding check for the wireless link status on your device.

[wiz@Arch-DOC ~]# iwconfig

[wiz@Arch-DOC ~]# netctl is-enabled wlp2s0b1-myrouter
Failed to get unit file state for netctl@wlp2s0b1\x2dh\x40Ck3r.service: No such file or directory

There's an even simple program called wifi-menu which scans and displays available SSID's in the vicinity.

This creates a profile in the /etc/netctl/ upon successful authentication  connection  with the
 [wiz@Arch-DOC netctl]# cat wlp2s0b1-myrouter
Interface=wlp2s0b1
Connection=wireless
Security=wpa
ESSID=myrouter
IP=dhcp
Key=myp@ssword


[wiz@Arch-DOC ]# netctl start wlp2s0b1-myrouter 

Type iwconfig, and it should listout the active wireless link details.



Now, to enable the wireless interface across restarts/reboots, do the following to ensure it is enabled and loaded

[wiz@Arch-DOC ]# netctl is-enabled wlp2s0b1-myrouter
Failed to get unit file state for netctl@wlp2s0b1\x2dmyrouter.service: No such file or directory

[wiz@Arch-DOC ]# netctl enable wlp2s0b1-myrouter

[wiz@Arch-DOC ]# netctl is-enabled wlp2s0b1-myrouter

Description-en: Media Transfer Protocol (MTP) library tools

 libmtp is a library for communicating with MTP aware devices in POSIX

 compliant operating systems.  It implements MTP Basic, the subset

 proposed for standardization.

 .

 The Media Transfer Protocol (commonly referred to as MTP) is a devised

 set of custom extensions to support the transfer of music files on

 USB digital audio players and movie files on USB portable media players.

 .

 This package contains tools for communicating with MTP devices.

Here's what the libraries intend

Description-en: Filesystem in Userspace (development)

 Filesystem in Userspace (FUSE) is a simple interface for userspace programs to

 export a virtual filesystem to the Linux kernel. It also aims to provide a

 secure method for non privileged users to create and mount their own filesystem

 implementations.

 .

 This package contains the development files.

Package: libmad0-dev

Description-md5: bf2478178701150aac144fa1b8a3ff5f

Description-en: MPEG audio decoder development library

 MAD is an MPEG audio decoder. It currently only supports the MPEG 1

 standard, but fully implements all three audio layers (Layer I, Layer II,

 and Layer III, the latter often colloquially known as MP3.)

 .

 This is the package you need to develop or compile applications that use MAD.

And we have one more package which is mtpfs filesystem, which can be downloaded from https://packages.debian.org/sid/amd64/mtpfs/download or you can enable the Testing SID repos and you can fetch it from. 

apt-get install mtpfs

Package: jmtpfs

Description-md5: 05e78b7506b9ac6b1d84a446189e832e

Description-en: FUSE based filesystem for accessing MTP devices

 jmtpfs is a FUSE and libmtp-based filesystem for accessing MTP (Media Transfer

 Protocol) devices. It was specifically designed for exchanging files between

 Linux (and Mac OS X) systems and newer Android devices that support MTP but

 not USB Mass Storage.

 .

 The goal is to create a well-behaved filesystem, allowing tools like find and

 rsync to work as expected. To enable certain Android apps to detect and use

 the transferred files, MTP file types are set automatically based on file

 contents using libmagic.

Package: mtpfs

Description-md5: 587c52dadb2cdcd42b55b3a80018a714

Description-en: FUSE filesystem for Media Transfer Protocol devices

 MTPfs is a FUSE filesystem that supports reading and writing from MTP (Media

 Transfer Protocol) devices, such as MP3 players, video players or digital

 cameras.

 .

 In addition to revealing media files on the connected device, MTPfs exposes a

 virtual directory called "/Playlists" which contains the device's playlists as

 m3u files.
