gzip -cd <file> | more

Please note that this is only likely to work when there is only one file in the archive. When there are more than one, then only the first file is displayed and the rest of the files are likely skipped. In which case, following should work.

tar -tvf file_name

Similarly, if there are tar or tar.gz files, following holds true.

Task: List the contents of a tar file

Use the following command:
$ tar -tvf file.tar

Task: List the contents of a tar.gz file

Use the following command:
$ tar -ztvf file.tar.gz

Task: List the contents of a tar.bz2 file

Use the following command:
$ tar -jtvf file.tar.bz2

Where,

• t: List the contents of an archive
• v: Verbosely list files processed (display detailed information)
• z: Filter the archive through gzip so that we can open compressed (decompress) .gz tar file
• j: Filter archive through bzip2, use to decompress .bz2 files.
• f filename: Use archive file called filename

Simply, it works similarly the way that cp works, except that you need to indicate login credential and remote server name.

So to copy files from remote server to current server, a syntax would look something like ...

#scp remote_user@remote_server:/remote/directory/some_file /local/directory/

And to copy files from local to remote, it would look like ....

#scp /local/directory/somefile remote_user@remote_server:/remote/directory/

You can also use options like -r to copy directories as well.

#scp -r remote_user@remote_server:/remote/directory /local/directory

There are other options you can easily find from man pages...

But this can be avoided by using the flag –lock-tables=false into the command line.

$mysqldump --opt -u [user.ID] -p -A --lock-tables=false > [dump.filename]

After that, it was easy as just moving file from one server to another using any secure method you like and using following command to restore it on to the new server...

mysql -u root -p[root_password] [database_name] < dumpfilename.sql

Note: if no database exist in your new server [database_name] can be omitted.

And that's it, your new database is all new and shiny...

apt-get install rsync

to install the latest version.

Once installed you'll need two servers to properly test it. First of all, as you are accessing other server you will need an account on all servers. Also, since rsync doesn't have secure transfer by default, make sure to install open-ssh on both servers to transfer files securely.

Some common options are:

• --delete : delete files that don't exist on sender (system) (Use with caution!!!)
• -v : Verbose (try -vv for more detailed information)
• -e "ssh options" : specify the ssh as remote shell
• -a : archive mode
• -r : recurse into directories
• -z : compress file data
• progress: will show the percentage of the file copied

Example commands:

Copy files from local server to remote server

$ rsync -v -e ssh /[local folder]/[local file] [remote.user]@[remote.server]:~

Copy files from remote server to local server

$ rsync -v -e ssh [remote.user]@[remote.server]:~/[remote.file] /[local.folder]

Synchronize directories from local server to remote server

$ rsync -r -a -v -e "ssh -l [remote.user]" [remote.server]:/[remote.directory]/ /[local]/[directory]

Synchronize directories from remote server to local server

$ rsync -r -a -v -e "ssh -l [remote.user]" [remote.server]:/[remote.directory] /[local]/[directory]

There other features such as excluding files while syncing and mirroring folders. Also, this process can be easier if password less authentication is set up between two servers. However, most of the basic use is covered above.

Then comes Denis Kozlov and his nifty renamer.

This thing just puts all those years of trying to learn regular expression into shame.

There are many applications that he had created as a Hobby, which also deserves a mentions are as follows.

• Shutter: Shutter is a multifunctional shutdown utility, which has a user friendly and easy-to-use interface and supports many different Events and Actions. Events: Countdown, On Time, Winamp Stops, Low CPU Usage, User Inactive, Battery Low, Window Closes, Process Stops, Ping Stops, File Size Limit. Actions: Shutdown, Reboot, LogOff, Lock Workstation, Sleep, Hibernate, Monitor Turn Off, Mute/UnMute Master Volume, Hang Up, Alarm.
• CPUMon: CPUMon is a simple little gadget to monitor CPU performance from your desktop. It displays a real-time graph of CPU performance as well as current usage indicator. The display supports custom colors, alpha-blending, user defined update rates and more. Some of the features: transparency, alpha-blending, customizable colors, layout presets, form locking, constantly updated CPU speed for mobile processors, tray icon mode, statistics, memory usage, and much more.
• Hasher: Program emerged as a result of a BackUp Utility project break-up. Basic idea for this part of the project is to calculate hash/checksum for a file. Has a simple interface for comparing Hashes of two files dropped to the form sequentially, and it also can calculate a Hash for a string.
• Hooker: Lightweight keyboard spy. Some of the features: stealth mode, log encryption, capturing of clipboard changes and currently used process, log viewer. Public version has several limitations: program shows itself when started; stealth mode is deactivated when hot key is pressed (without password prompt).
• Colors: Color picker that helps users easily select a desired color using various pallets. It is able to pick color from the currently displayed screen content and supports a number of different color models, i.e. RGB, HSV, HLS, CMYK.
• Scripter: Script execution tool based on Pascal programming language. Contains wide range of built-in functions to simplify automation of common tasks. Supports command-line execution of scripts.
• RandPass: Random password generator. Simple tool for generating random passwords based on specified character set with customizable output format.

All of the applications are available to be downloaded from his website.
