Check These Out
txt2regex can be interactive or noninteractive and generates regular expressions for a variety of dialects based on user input. In interactive mode, the regex string builds as you select menu options. The sample output here is from noninteractive mode, try running it standalone and see for yourself. It's written in bash and is available as the 'txt2regex' package at least under debian/ubuntu.
You need to have fortune and cowsay installed. It uses a subshell to list cow files in you cow directory (this folder is default for debian based systems, others might use another folder).
you can add it to your .bashrc file to have it great you with something interesting every time you start a new session.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
Installs pip packages defining a proxy
you can put almost any command.
$notify-send -t 0 "MOTD" "$(sed -n '/#^4/,/#$4/{/#^4\|#$4/!p}' motd2 | cut -d# -f2)"
$notify-send -t 0 "readfile" "$(while read mess; do echo $mess;done < motd2)"
If are a Bash user and you are in a directory and need to go else where for a while but don't want to lose where you were, use pushd instead of cd.
cd /home/complicated/path/.I/dont/want/to/forget
pushd /tmp
cd thing/in/tmp
popd (returns you to /home/complicated/path/.I/dont/want/to/forget)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Splits the input based on commas and prints it in a nice column format. This would not work for CSV rows that have "," between quotes or with newline characters. Use only simple simple csv files.
A bitcoin "brainwallet" is a secret passphrase you carry in your brain.
The Bitcoin Brainwallet Private Key Base58 Encoder is the third of three functions needed to calculate a bitcoin PRIVATE key from your "brainwallet" passphrase.
This base58 encoder uses the obase parameter of the amazing bc utility to convert from ASCII-hex to base58. Tech note: bc inserts line continuation backslashes, but the "read s" command automatically strips them out.
I hope that one day base58 will, like base64, be added to the amazing openssl utility.
