Purpose: Provides an additional layer of safety when executing Bash scripts, by: disabling aliases or functions whose name conflicts with built-in keywords; and enabling shell options that perform additional safety checks.
Unit Test Scripts: No unit test scripts exist for sanitize.
Requires Modules: None
Required By Modules: None
sanitize can be sourced by scripts to help protect against situations in which user-defined functions and aliases interfere with built-in Bash keywords. Additional shell safety options are also enabled. Sanitization is entirely optional, and does not require bashful.inc.sh to have been loaded first.
The calling script should execute the following statements to sanitize the script environment:
source "${0%/*}/bashful/bashful-sanitize.inc.sh" || exit 1
To be extra cautious against scenarios where the source keyword may have been overridden, execute the following statements:
POSIXLY_CORRECT=1 && builtin unset -f builtin source unset POSIXLY_CORRECT
source "${0%/*}/bashful/bashful-sanitize.inc.sh" || exit 1
