bashsh v0.1.5

Bashsh

Improves your Bash scripts.

Installation via NPM

npm install -g bashsh

Installation via bpkg

bpkg install -g mcrio/bashsh

Usage

The following shebang

#!/usr/bin/env bashsh-0

gives you:

• set -e by default:

  echo hello ; false ; echo world

  will only print hello.

• CMD for showing executed commands in bold on stderr:

  CMD git status

• CMD_STR prints the string in bold on stderr and runs it with eval:

  CMD_STR 'gitk --all &'

• ECHO prints the string in bold on stderr:

  ECHO wget ... example.com
  wget --cookies=on --load-cookies wget-tmp/cookies.txt --keep-session-cookies --save-cookies wget-tmp/cookies.txt example.com

• MSG prints a remark in bold on stderr, formatted as a comment:

  MSG hello world

  prints # hello world.

• READ_P works like read -p but prints the first parameter using MSG:

  READ_P 'What is your name? ' your_name

• QUOTED prints the given arguments in a way that is safe to pass to commands:

  echo "My arguments are: $(QUOTED "$@")"

You can find a few examples in the examples directory. Also, my ~/bin directory makes heavy use of this project.

Caveats / known limitations

You cannot just

npm install bashsh

and then use

#!/usr/bin/env ./node_modules/.bin/bashsh-0

as the path of the command supplied to env will be interpreted as relative to the working directory, not to the script's directory.
