Check These Out

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)

List Listen Port by numbers
Show TCP Listen ports sorted by number (bugs: IPV6 addresses not supported)

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Runs previous command replacing foo by bar every time that foo appears
To replace foo by bar, but not execute, do ^foo^bar^:p To replace all foo by bar, but not execute, do ^foo^bar^:&:p

check open ports without netstat or lsof

Access partitions inside a LVM volume
kpartx can be found inside of the multipath-tools package -a adds the mappings and -d deletes them

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

Run a program transparently, but print a stack trace if it fails
For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files. The one downside is that it does smoosh your program's stderr and stdout together.

FInd the 10 biggest files taking up disk space

Copy ssh keys to user@host to enable password-less ssh logins.
Same as original just no $ at start
