This is my collection of UNIX shell configuration files and utilities. These days I only use them with zsh and bash on Linux, but in the past I also used them on various Solaris and FreeBSD machines, and for the most part they should work on any POSIX-oriented UNIX.
-
Configuration files for zsh
.zshrc
- config for interactive instances only.zshenv
- config for non-interactive and interactive instances.zsh/
hierarchy, including:.zsh/functions/
- various handy interactive and completion functions.zsh/accounts.d/
- for configuring completion of (user, host) pairs.zsh/users.d/
- for configuring completion of users
-
Configuration files for bash
.bashrc
- config for interactive instances only.bash_profile
- config for interactive "login shell" instances only.bashenv
- config for non-interactive and interactive instances
-
Configuration files to be shared by any Bourne-compatible shell
.shared_env
- config for non-interactive and interactive instances.shared_rc
- config for interactive instances only
-
Mechanism for automatically switching between shells.
Useful for when you do not have root privileges and want to run a locally compiled version ofzsh
rather than a system-wide shell. See: -
Perl library
lib/perl5/Sh.pm
providing some handy native Perl replacements for shell-like operations. -
Hook-runner mechanism for building composite configuration out of multiple files in a
foo.d/
hierarchy. For more information see:doc/ConfigHooks.org
.zsh/functions/find_hooks
- find applicable hook files underneathfoo.d/
hierarchy.zsh/functions/run_hooks
- run hook files found byfind_hooks
, assuming that they contain shell codelib/libhooks.sh
- concatenate hook files found byfind_hooks
into a single configuration file which can then be consumed by an external program such asssh
,mutt
,crontab
etc.
-

less
rsync
ls
readline

This repository is designed to be stowed directly into your home directory:
git clone git:https://github.com/aspiers/shell-env.git
stow -d . -t ~ shell-env
However if you only want to cherry-pick bits and pieces then you can easily just copy or symlink them in manually. Just be aware that some of the files depend on other files, especially the shell configuration files.
