Stat each file in a directory
This will run stat on each file in the directory.

List .log files open by a pid
Uses lsof to display the full path of ".log" files opened by a specified PID.

AWK Calculator

Find the biggest files on your hard drive

Prepend a text to a file.

subtraction between lines
It's allways strange for me to see sed and awk in the same command line if you can avoid it

Kill multiple instances of a running process

View acceptable client certificate CA names asked for during SSL renegotiations
The key is to use the -prexit option at the command line, and then type "quit" instead of CTRL-C to exit OpenSSL. OpenSSL will then dump its last negotiated state, printing out the contents of the renegotiated handshake. Crucial for debugging client certificate configurations on web servers such as IIS, which renegotiate the SSL/TLS connection with the HTTP request in-flight to ask the client for a cert.

Match a URL
For the record: I didn't build this. Just shared what I found that worked. Apologies to the original author! I decided I should fix the case where http://example.com is not matched for the next time I need this. So I read rfc1035 and formalized the host name regex. If anyone finds any more holes, please comment.

When feeling down, this command helps
$ sudo apt-get install sl $ man sl
