I use this all the time for taking manual backups of stuff i want to keep but not important enough to backup regularly.

You can convert a FAT or FAT32 volume to an NTFS volume without formatting the drive, though it is still a good idea to back up your data before you convert.

host `hostname`
2009-02-18 05:48:29
User: rommelsharma
Functions: host

This is a useful command that gives the hostname and the IP Address of your machine, on many OS. Tested on Linux and Solaris.

host command here is followed by `hostname`. Note the ` in the command is a back quote (or grave accent or back tic that usually shares the space with the ~ key). No other options are specified. See sample output.

This command lets you view the cam on remote machine whilst connected via ssh. Note: must connect to remote machine with ssh -Y.

find . | grep deleteme | while read line; do rm $line; done
2009-02-18 00:55:57
User: tec
Functions: find grep read rm

This command deletes all files in all subfolders if their name or path contains "deleteme".

To dry-run the command without actually deleting files run:

find . | grep deleteme | while read line; do echo rm $line; done

Sends the microphone input from PC1 to the speakers of PC2. Do the same in reverse to have an actual conversation ;) ... maybe with another port tough

I know there are a lot of random password generators out there, but I wanted something that put out something besides hex. Set count equal to the number of bytes you want.

defaults write com.apple.dashboard mcx-disabled -boolean YES; killall Dock
2009-02-17 23:22:24
User: starchox
Functions: killall write

Dashboard is OS X utility application. When you hit F12, Dashboard springs forward, dimming the background, some people have claimed memory or performance problems. In my case, I just don't use it, there may be other reasons you?d rather not have Dashboard available.

Change YES to NO to restore the previous functionality.

defaults write com.apple.finder NSUserKeyEquivalents -dict 'New Finder Window' '@$N' 'New Folder' '@N'; killall Finder
2009-02-17 23:20:53
User: Vulpine
Functions: killall write

In Mac OS 9, the "New Folder" keyboard shortcut was Command+N, but in Mac OS X this was changed to "New Finder Window" instead, with "New Folder" taking the more awkward shortcut of Command+Shift+N. This command reverses their mappings.

defaults write com.apple.Dock no-glass -boolean YES; killall Dock
2009-02-17 23:01:58
User: Vulpine
Functions: killall write

Mac OS X 10.5 (Leopard) introduced a new, 3D, reflective Dock. For those of us who prefer the Dock to be a little less distracting, this command is the answer. The Dock will be rendered in the same style as when pinned to the left- or right-hand side of the screen. Replace YES with NO to restore the 3D Dock.

find . -name ".svn" -exec rm -rf {} \;
2009-02-17 23:00:30
User: mihaibojin
Functions: find rm

If you need to delete all redundant ".svn" directories from a given path and all its subdirectories, use this command !

Particulary useful if you want to upload to an ftp server, but don't use svn or if you need to update/backup some source code to another directory.

You can also try "svn export . /new/path/without/svn/dirs" (also from the CLI)

wget --random-wait -r -p -e robots=off -U mozilla http://www.example.com
2009-02-17 22:53:07
User: starchox
Functions: wget

-p parameter tells wget to include all files, including images.

-e robots=off you don't want wget to obey by the robots.txt file

-U mozilla as your browsers identity.

--random-wait to let wget chose a random number of seconds to wait, avoid get into black list.

Other Useful wget Parameters:

--limit-rate=20k limits the rate at which it downloads files.

-b continues wget after logging out.

-o $HOME/wget_log.txt logs the output

msiexec.exe /i product.msi /l* c:\folder\LogFileName.txt
mysqldump -uUserName -pPassword tudb | ssh root@rootsvr.com "mysql -uUserName -pPassword -h mysql.rootsvr.com YourDBName"
2009-02-17 22:36:06
User: elecboy
Functions: ssh

This option makes a copy of your current db and via ssh it transfer to the server you specify and upload the database to the specific User & Password you specify (Note the db User & Pass, can be different from the one you use in the other server)

If you are going to use "localhost" as your main db remove (-h) and youst add "localhost"

Use this command to find out a list of committers sorted by the frequency of commits.

echo "^[]0;My_Title_Goes _Here^G"
2009-02-17 20:46:06
User: TheNomad
Functions: echo

If you are using an xterm emulation capable terminal emulator, such as PuTTY or xterm on Linux desktop, this command will replace the title of that terminal window. I know it is not nice to have seventeen terminals on your desktop with title PuTTY, you can not tell which one is connected to which server and doing what.

Even though the string between the quotes is typed as literals, it needs a little more finesse to make it work. Here is how it is done key-by-key:

echo "( ctrl-v then ctrl-[ )0;Enter_Title_String_Here( ctrl-v then ctrl-g )"( enter )

ctrl-v : means hold down ctrl key and hit v at the same time like you are pasting in windoze ; also please don't type the parentheses, i.e., ( and )

ps -ef | grep $USERNAME | awk {'print $2'} | xargs kill [-9]
2009-02-17 20:35:35
User: TheNomad
Functions: awk grep kill ps xargs

This is a 'killall' command equivalent where it is not available.

Prior to executing it, set the environment variable USERNAME to the username, whose processes you want to kill or replace the username with the $USERNAME on the command above.

Side effect: If any processes from other users, are running with a parameter of $USERNAME, they will be killed as well (assuming you are running this as root user)

[-9] in square brackets at the end of the command is optional and strongly suggested to be your last resort. I do not like to use it as the killed process leaves a lot of mess behind.

ls -lrt
2009-02-17 19:51:08
User: guidouil
Functions: ls

Show you the list of files of current directory sorted by date youngest to oldest, remove the 'r' if you want it in the otherway.

concatenate local RSA to remote machine's authorized_keys

User: wesrog

You'll want to use this for passwordless logins. Same as ssh-copy-id, if you don't have it on your system.

find /home -uid 1056 -exec chown 2056 {} \;
2009-02-17 19:42:50
Functions: chown find

Finds all files in /home owned by UID 1056 and changes to 2056.

find . -size +10240k -exec ls -l {} \; | awk '{ print $5,"",$9 }'|sort -rn > message.out
2009-02-17 19:39:56
User: rommelsharma
Functions: awk find ls

This command specifies the size in Kilobytes using 'k' in the -size +(N)k option. The plus sign says greater than. -exec [cmd] {} \; invokes ls -l command on each file and awk strips off the values of the 5th (size) and the 9th (filename) column from the ls -l output to display. Sort is done in reversed order (descending) numerically using sort -rn options.

A cron job could be run to execute a script like this and alert the users if a dir has files exceeding certain size, and provide file details as well.
