Rc is a command interpreter for Plan 9 that provides similar facilities to UNIX’s Bourne shell, with some small additions and less idiosyncratic syntax. This paper uses numerous examples to describe rc’s features, and contrasts rc with the Bourne shell, a model that many readers will be familiar with.
direnv is an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory. Load 12factor apps environment variables. Create per-project isolated development environments. Load secrets for deployment.
Before each prompt, direnv checks for the existence of a .envrc file in the current and parent directories. If the file exists (and is authorized), it is loaded into a bash sub-shell and all exported variables are then captured by direnv and then made available to the current shell.
It supports hooks for all the common shells like bash, zsh, tcsh and fish. This allows project-specific environment variables without cluttering the ~/.profile file.
Because direnv is compiled into a single static executable, it is fast enough to be unnoticeable on each prompt. It is also language-agnostic and can be used to build solutions similar to rbenv, pyenv and phpenv.
A set of shell scripts and aliases that improve your shell usage. Automatically prints system status reports when a shell boots up, does basic monitoring, sets useful aliases, can even print an ASCIIfied logo when you log in. Tries to be configurable; you can pick only the stuff you want when you install it and has its own configuration files. Called from your ~/.bashrc file. Easy to uninstall, too:
- (remove the calls to synth-shell from your ~/.bashrc file)
rm -rf ~/.config/synth-shell/
Does not work so well on OSX. Seems to be Linux-specific, regardless of the fact that it uses bash.
A quick, fast, and easy reverse shell generator for bash, Lua, netcat, PHP, and other tools and languages.
Eternal Terminal (ET) is a remote shell that automatically reconnects without interrupting the session. A layer in between an application and unix TCP sockets that make the sockets robust to TCP disconnects including roaming and connection failure. Implements some of the tmux user experience, even works with the tmux control center (tmux -CC). Buffers bytes written and read so they can be replayed in the event of a disconnection. Starts with SSH to make the initial connection and authentication. After that, it uses its own encrypted network protocol.
An alternative initramfs for Linux that offers additional technical capability. Boot from systems with some combination of encrypted storage, softraid, and LVM. Has a minimal rescue environment that you can SSH into. Even supports booting into and restoring suspended systems.
SecLists is the security tester's companion. It's a collection of multiple types of lists used during security assessments, collected in one place. List types include usernames, passwords, URLs, sensitive data patterns, fuzzing payloads, web shells, and many more. Some of this stuff can be used to prime discovery operations.
How to make cronjobs run stuff in shells with full sets of environment variables.
An open source GUI app for Linux which helps you clean out old tempfiles and logs that are taking up disk space. The fact that this also makes for good personal information hygine is parenthetical. Can clean out files for Firefox, bash, Beagle, Flash, and more.
