+# CBMC Autocomplete Scripts for Bash
+This directory contains an autocomplete script for bash.
+## Installation
+1. Compile cbmc and
+
+2. `cd scripts/bash-autocomplete`
+
+3.  `./extract-switches.sh`
+
+4. Put the following at the end of you in your `~/.bashrc`, with the directories adapted to your directory structure:
+    ```bash
+    cbmcautocomplete=~/diffblue/cbmc/scripts/bash-autocomplete/cbmc.sh
+    if [ -f $cbmcautocomplete ]; then
+      . $cbmcautocomplete
+    fi
+    ```
+## Usage
+As with the usual autocomplete in bash, start typing a switch to complete it, for example:
+```
+cbmc --clas<TAB>
+```
+will complete to
+```
+cbmc --classpath
+```
+
+## Features implemented
+
+* Completing all switches
+* Completing values for `--cover`, `--mm` and `--arch`
+* When completing a name of a file to analyze, only files with supported extensions are shown.
