You might also find [https://www.amahi.org/apps/shellcheck 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 ==<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. <b><u>Dependencies Installed for Scripts</u></b> * sysinfo: pciutils and procinfo * smartchk: smartmontools * dsalert: smartmontools <b><u>dos2unix (installed with this application)</u></b> What is it? <blockquote>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. </blockquote> Why would I need this tool? <blockquote>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.</blockquote> 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. ===Disk Space===

=== 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.
# 11/8/2010
#
log = '/var/log/hda-updates.log' f = open(log, 'r')
lines = f.readlines()
f.close()
gotUpdates = False
firstUpdate = False
# 11/8/2010
#
# Updated by bigfoot65# 9/26/2014#
log = '/var/log/hda-updates.log'
line = '==============================================================================='
head = 'Package Arch Version Repository Size'
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
# A blank line terminates the updates for a particular date
if gotUpdates :
gotUpdates = False
continue
# Reformat the file info slightly
updateInfo = l.split()
print purple + l + white
print blue + line + white
Here is a snippet of its output on my system:
