Today, a new version, i.e., GNU Bash 4.4 has arrived with a wide set of changes and feature additions. Let’s take a look at some of its new features:
- A new variable in the form of EXECIGNORE, which will cause matching filenames to be ignored while searching for commands.
- The ‘kill’ bulletin comes with a new ‘-L’ option.
- Just like other shells, command and process substitutions now turn off ‘-v’ option when executing.
- A new family of operators, ${[email protected]}, to transform the value of ‘parameter’.
- A new ‘–enable-function-import’ configuration option has been added for importing shell functions from the environment.
- Now Bash uses mktemp() when creating internal temporary files. On many Linux systems, it produces a warning at build time.
Apart from this small list of changes, one can find the complete list of features and changes since the version 4.3 in the Bash 4.4 change log.
Along with GNU Bash, many new changes have also been brought to GNU Readline, which is a software library that provides history and line-editing capabilities to Bash.
