Check These Out

Exit shell faster
Use ^D instead of exit. Also ^D ends input stream when you use terminal for typing into standard input.

reverse order of file

Diff two directories by finding and comparing the md5 checksums of their contents.
Compute the md5 checksums for the contents of two mirrored directories, then sort and diff the results. If everything matches, nothing is returned. Otherwise, any checksums which do not match, or which exist in one tree but not the other, are returned. As you might imagine, the output is useful only if no errors are found, because only the checksums, not filenames, are returned. I hope to address this, or that someone else will!

Convert filenames from ISO-8859-1 to UTF-8
Nothing advanced, it just finds filenames that are stored with ISO-8859-1 characters and and converts those into UTF-8. Recommended to use without the --notest flag first so you can see what will be changed.

socat TCP-LISTEN:5500 EXEC:'ssh user@remotehost "socat STDIO UNIX-CONNECT:/var/run/mysqld/mysqld.sock"'
Listens on local port 5500 and connects to remotehost with username user to tunnel the given socket file. Will work with anything, but can be useful if there's a need for a local application to connect with a remote server which was started without networking.

show the real times iso of epochs for a given column
When you have one of those (log)files that only has epoch for time (since no one will ever look at them as a date) this is a way to get the human readable date/time and do further inspection. Mostly perl-fu :-/

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

Countdown Clock
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

Shows space used by each directory of the root filesystem excluding mountpoints/external filesystems (and sort the output)
Useful to see at glance which directory under the root file is using most space

Adding specific CustomLog for each Virtual Domain of Apache
