helpful-unix-like-scripts

Helpful Linux and macOS shell scripts for sysadmins, developers and the forgetful.

The clean command script previously located clean-command-history is now part of this repository. Less for me to maintain and just makes sense. It's helpful and a Unix-like shell script. 🙂

• bash_aliases.sh
• caffeinate.sh
• clean.sh
• git-sync.sh
• swupdate.sh
• theme-helper.sh
• whatsmyip.sh
• zsh_aliases.sh

Install Script

Install the bash_aliases, zsh_aliases, and others scripts using the included INSTALL script with:

./INSTALL

macOS Support

When using the default zsh shell on newer macOS releases. You will likely, need to add the following code snippet to the hidden ~/.zshrc file.

# Disable the sessions save and restore mechanism.
SHELL_SESSIONS_DISABLE=1

# Include zsh_aliases if available.
if [[ -f "$HOME/.zsh_aliases" ]]; then
	source "$HOME/.zsh_aliases"
fi

Here's my custom ~/.zshrc file, which includes some other helpful aliases and zsh settings: automatic completion, some basic color support, use nano or pico as the default text editor, some ls aliases found in Ubuntu, etc.

# System-wide profile for interactive zsh(1) login shells.

# See zshbuiltins(1) and zshoptions(1) for more details.

zstyle ":completion:*" completer _complete _ignored
zstyle :compinstall filename "$HOME/.zshrc"
autoload -Uz compinit; compinit

# Disable the sessions save and restore mechanism.
SHELL_SESSIONS_DISABLE=1

# Enable default text editor
export EDITOR="nano"
export VISUAL="$EDITOR"

# Enable color support for ls and other commands.
alias egrep="egrep --color=auto"
alias fgrep="fgrep --color=auto"
alias grep="grep --color=auto"
alias ls="ls --color=auto"

# More handy aliases for the ls command.
alias l="ls -CF"
alias la="ls -A"
alias ll="ls -AlhF"

# Include zsh_aliases if available.
if [[ -f "$HOME/.zsh_aliases" ]]; then
	source "$HOME/.zsh_aliases"
fi

On macOS, If you want these scripts to execute using zsh instead of bash, must change the shabang from #!/usr/bin/env bash to #!/usr/bin/env zsh for each script. This extra step is not currently required. However; likely to prevent issues, should Apple remove their legacy version of bash from the operating system.

OpenWrt and LEDE Support

On OpenWrt based devices and similar, you may need to change the shabang from #!/usr/bin/env bash to #!/usr/bin/env sh for each script, or whatever shell is supported on the device. Like the changes outlined above for macOS, force these scripts to execute using sh the default shell for the operating system.
