Check These Out

create and md5 sum of your password
create and md5 sum of your password without it showing up in your terminal or history. Afterwards we overwrite the $p variable (thx to bazzargh)

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Recursively chmod all dirs to 755 and all files to 644

Get table column names from an MySQL-database in comma-seperated form

exclude a column with cut
Show all columns except 5th. This might help you save some typing if you are trying to exclude some columns from the output.

Sorted, recursive long file listing
Tells you everything you could ever want to know about all files and subdirectories. Great for package creators. Totally secure too. On my Slackware box, this gets set upon login: $ LS_OPTIONS='-F -b -T 0 --color=auto' and $ alias ls='/bin/ls $LS_OPTIONS' which works great.

execute your commands hiding secret bits from history records
$ wget --user=username --password="$password" http://example.org/ Instead of hiding commands entirely from history, I prefer to use "read" to put the password into a variable, and then use that variable in the commands instead of the password. Without the "-e" and "-s" it should work in any bourne-type shell, but the -s is what makes sure the password doesn't get echoed to the screen at all. (-e makes editing work a bit better)

back ssh from firewalled hosts
host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

Sort a character string
Sorts a character string, using common shell commands.

Automatically connect to a host with ssh once it is online
