<b><u>Terminal Scripts Application README FILE</u></b>
 +
 
 +
The following scripts are included:
 +
* automysqlbackup: Backup multiple MySQL databases on a given schedule.
 +
* diskspace: Displays graphical depiction of all drive space used and remaining.
 +
* dnflog: Shows latest Fedora updates that have been applied.
 +
* dsalert: Sends email if a disk has used a set percentage of space. Requires the system have outgoing email capability.
 +
* folderspace: Displays how much space a specific folder occupies.
 +
* hdaupdates: Shows latest Amahi updates to your HDA.
 +
* smartchk: Provides health status of disks drives set in the script.
 +
* systeminfo: Displays various criteria about the system, to include host name, IP address, uptime, etc.
 +
* weather: Shows weather for a given location as preset in the script.
 +
 
 +
 
 +
ALL the above scripts may require some modification for your system.
 +
 +
* systeminfo and weather script has a variable that must be changed for your geographical area.
 +
* smartchk requires modification to list all mounted hard disk drives in your system.
 +
* automysqlbackup has various settings will need adjusted for your system.  See the [[https://wiki.amahi.org/index.php/Database_Backup:automysqlbackup]] page for details.

Here is a simple script that displays all of the file updates and additions made to your hda and the date they happened. It simply reads the hda-updates.log file and parses out only the relevant changes.
 +
 
 +
I use this script periodically so I can see what might have changed recently.
 +
 
 +
'''Installation'''
 +
 
 +
Log into your hda and create a bin directory under your home directory (if you don't already have one). The reason for this is that ~/bin is already in your $PATH when you log in, so it will automatically find any scripts you put there:
 +
    cd /usr/bin
 +
 
 +
Open up your favorite editor (I suggest gedit for this) and copy the code that follows into the editor. Save the file as '''hda-updates''' (or whatever you want to name it) and exit the editor.

This is recommended only for advanced users, proceed with caution.


The scripts below are now included in the Amahi Terminal Scripts application. You might also find ShellCheck helpful when developing scripts.

Use of script files provides many useful results. Below is a small collection that should enhance your command line experience.

README1ST

Terminal Scripts Application README FILE

The following scripts are included:

  • automysqlbackup: Backup multiple MySQL databases on a given schedule.
  • diskspace: Displays graphical depiction of all drive space used and remaining.
  • dnflog: Shows latest Fedora updates that have been applied.
  • dsalert: Sends email if a disk has used a set percentage of space. Requires the system have outgoing email capability.
  • folderspace: Displays how much space a specific folder occupies.
  • hdaupdates: Shows latest Amahi updates to your HDA.
  • smartchk: Provides health status of disks drives set in the script.
  • systeminfo: Displays various criteria about the system, to include host name, IP address, uptime, etc.
  • weather: Shows weather for a given location as preset in the script.


ALL the above scripts may require some modification for your system.

  • systeminfo and weather script has a variable that must be changed for your geographical area.
  • smartchk requires modification to list all mounted hard disk drives in your system.
  • automysqlbackup has various settings will need adjusted for your system. See the [[1]] page for details.


Dependencies Installed for Scripts

  • sysinfo: pciutils and procinfo
  • smartchk: smartmontools
  • dsalert: smartmontools


dos2unix (installed with this application)

What is it?

dos2unix is a tool to convert text files from DOS line endings (carriage return + line feed) to Unix line endings (line feed). It is also capable of conversion between UTF-16 to UTF-8. Invoking the unix2dos command can be used to convert from Unix to DOS. This tool comes in handy when sharing files between Windows and Linux machines.

Why would I need this tool?

While editing files on a machine running some form of Windows and uploading them to a Linux server is convenient, it can cause unforeseen complications. Windows-based text editors put special characters at the end of lines to denote a line return or newline. Normally harmless, some applications on a Linux server cannot understand these characters and can cause the service to not respond correctly. There is a simple way to correct this problem: dos2unix.

The dos2unix command is a simple way to make sure that files that have been edited and uploaded from a Windows machine to a Linux machine work and behave correctly.

HDA Updates

Here is a simple script that displays all of the file updates and additions made to your hda and the date they happened. It simply reads the hda-updates.log file and parses out only the relevant changes.

I use this script periodically so I can see what might have changed recently.

Installation

Log into your hda and create a bin directory under your home directory (if you don't already have one). The reason for this is that ~/bin is already in your $PATH when you log in, so it will automatically find any scripts you put there: 

   cd /usr/bin

Open up your favorite editor (I suggest gedit for this) and copy the code that follows into the editor. Save the file as hda-updates (or whatever you want to name it) and exit the editor.

Code: 

#!/usr/bin/python
#
# Dump update information from /var/log/hda-updates.log
#!/usr/bin/python
#
# Display the date and files that were modified/installed.
#
# Reads the hda-updates log file and parses out just the file updates/additions.
# It helps to see what has been modified and when.

log = '/var/log/hda-updates.log'
line = '==============================================================================='
head = 'Package                 Arch            Version           Repository     Size'
cyan = '\033[1;36m'
blue = '\033[1;34m'
purple = '\033[1;35m'
white = '\033[1;37m'
print blue + line + white
print cyan + head + white
print blue + line + white
f = open(log, 'r')
lines = f.readlines()
f.close()
gotUpdates = False
firstUpdate = False
dateInfo = ''
for ll in lines :
	l = ll.strip()
	# Ignore dependency heading
	if l == 'Installing for dependencies:' :
		continue
	if l == '' :
		# A blank line terminates the updates for a particular date
		if gotUpdates :
			gotUpdates = False
		continue
	if gotUpdates :
		if firstUpdate :
			# Display the date above the first update
			print '%s:' % dateInfo
			firstUpdate = False
		# Reformat the file info slightly
		updateInfo = l.split()
		print purple + l + white
		print blue + line + white
	if 'hda update attempt' in l :
		# This header appears once per hour in the log. Very few represent real updates.
		# Save the date information in case this is a real update.
		dateInfo = ' '.join(l.split()[5:])
	if 'Updating:' in l :
		# This is a real update, set up the flags
		gotUpdates = True
		firstUpdate = True

Make the file executable: 

   chmod +x hda-updates

Now you can run it.

   hda-updates
