Check These Out

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

Execute a command with a timeout
A timeout is great, but what if the command is taking longer than expected because it's hung up or ran into some other problem? That's where the -k option comes in. Run "some_command" and timeout after 30s. If the command is still running after 1 minute, it will receive a kill signal.

grep -v with multiple patterns.
You can use -e to pass multiple patterns.

Copy data using gtar
It copies the entire current working directory to the destination directory with compression enabled.

list block devices
Shows all block devices in a tree with descruptions of what they are.

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.

Clone all repos from a user with lynx
https://wuseman.github.io/wcloner/

Install pip with Proxy
Installs pip packages defining a proxy

ping a range of IP addresses
nmap accepts a wide variety of addressing notation, multiple targets/ranges, etc.

Start an X app remotely
Launch a gui app remotely. In this example smplayer is installed on the remote machine, and movie.avi is in the remote user's home dir. Note that stdout/stderr is still local, so you'll have feedback locally, add '&>/dev/null' to suppress. This is surprisingly not well known (compared to running an X app locally via ssh -X). (NB. if your distro requires ~/.Xauthority file present, then try -fX if you have problems) Resubmitted (and trimmed, thanks sitaram) due to ridiculous voting on previous submission. Fingers crossed, it gets a better rating this time.

Stay in the loop…

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
