Check These Out

Join lines
This command turns a multi-line file into a single line joined with <SOMETEXT>. To skip blank lines, use: $ perl -pe '(eof()||s/^\s*$//)||s/\n//g' file.txt

Check your bash shell for vulnerability to the ShellShock exploit
If this command prints 'x' then your shell is vulnerable. Null output confirms that you are protected. Further reading: http://allanmcrae.com/2014/09/shellshock-and-arch-linux/

To get the CPU temperature continuously on the desktop
No need for a colon, and one less semicolon too. Also untested.

Get windows IPv4 and nothing else
May be useful to get user's ip address over the phone, as users struggle to read through a long ipconfig result.

Debug SSH at the Maximum Verbosity Level
When debugging an ssh connection either to optimize your settings ie compression, ciphers, or more commonly for debugging an issue connecting, this alias comes in real handy as it's not easy to remember the '-o LogLevel=DEBUG3' argument, which adds a boost of debugging info not available with -vvv alone. Especially useful are the FD info, and the setup negotiation to create a cleaner, faster connection.

Copy uncommitted changes from remote git repository
Copy changed files from remote git repository, _including binary ones_, staged and unstaged alike. Note that this command doesn't handle deleted files properly.

find largest file in /var
find largest file in /var

Use nroff to view the man pages
Using nroff , it is possible to view the otherwise garbled man page with col command.

Change prompt to MS-DOS one (joke)

Pretty print SQL query with python in one line
You need to apt-get install python-sqlparse. This command simply formats a sql query and prints it out. It is very useful when you want to move a sql query from commandline to a shell script. Everything is done locally, so you don't need to worry about copying sql query to external websites.
