Check These Out

mysql DB size

Which processes are listening on a specific port (e.g. port 80)

Check your unread Gmail from the command line
notice what happens when there is more than one unread message in a thread... also people please dont hardcode the password when you use curl. Leave it out and curl will ask you when it runs. Please...?

Create a git alias that will pull and fast-forward the current branch if there are no conflicts
This command will first add an alias known only to git, which will allow you to pull a remote and first-forward the current branch. However, if the remote/branch and your branch have diverged, it will stop before actually trying to merge the two, so you can back out the changes. http://www.kernel.org/pub/software/scm/git/docs/git-pull.html Tested on git 1.5.6.1, msysgit (Windows port) Actually this is not really the way I want it. I want it to attempt a fast-foward, but not attempt to merge or change my working copy. Unfortunately git pull doesn't have that functionality (yet?).

How many files in the current directory ?
A simple "ls" lists files *and* directories. So we need to "find" the files (type 'f') only. As "find" is recursive by default we must restrict it to the current directory by adding a maximum depth of "1". If you should be using the "zsh" then you can use the dot (.) as a globbing qualifier to denote plain files: zsh> ls *(.) | wc -l for more info see the zsh's manual on expansion and substitution - "man zshexpn".

Put a console clock in top right corner
Gives not only date but also some interesting status about the System

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Calculate N!
Same as the seq/bc solution but without bc.

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Title Case Files
All words of the filenames except "a", "of", "that" and "to" are capitalized. To also match words which begin with a specific string, you can use this: $ rename 's/\b((?!hello\b|t)[a-z]+)/\u$1/g' * This will capitalize all words except "hello" and words beginning with "t".
