+title: Bash Autocomplete
+sort_key: C

+
+You can enable autocompletion in geth just running a bash script (Linux/MacOS) or a powershell script (Windows).
+
+### Linux/MacOS
+
+1.  Create a bash script file with the content below and save as `geth-autocompletion` anywhere in your computer (i.e. `/bin/geth-autocompletion`):
+
+    ```bash
+    #! /bin/bash
+
+    : ${PROG:=$(basename ${BASH_SOURCE})}
+
+    _cli_bash_autocomplete() {
+    if [[ "${COMP_WORDS[0]}" != "source" ]]; then
+        local cur opts base
+        COMPREPLY=()
+        cur="${COMP_WORDS[COMP_CWORD]}"
+        if [[ "$cur" == "-"* ]]; then
+        opts=$( ${COMP_WORDS[@]:0:$COMP_CWORD} ${cur} --generate-bash-completion )
+        else
+        opts=$( ${COMP_WORDS[@]:0:$COMP_CWORD} --generate-bash-completion )
+        fi
+        COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
+        return 0
+    fi
+    }
+
+    complete -o bashdefault -o default -o nospace -F _cli_bash_autocomplete $PROG
+    unset PROG
+    ```
+
+2.  Open and edit your **startup script** depending on the terminal in use (i.e. `~/.bashrc` or `~/.zshrc`).
+
+3.  Includes this command in the final of your **startup script**:
+
+    ```bash
+    # i.e. PROG=geth source /bin/geth-autocompletion
+    PROG=geth source /path/to/autocomplete/geth-autocompletion-script
+    ```
+
+### Windows
+
+1.  Create a powershell script file with the content below and save as `geth.ps1` anywhere in your computer.
+
+    ```bash
+    $fn = $($MyInvocation.MyCommand.Name)
+    $name = $fn -replace "(.*)\.ps1$", '$1'
+    Register-ArgumentCompleter -Native -CommandName $name -ScriptBlock {
+        param($commandName, $wordToComplete, $cursorPosition)
+        $other = "$wordToComplete --generate-bash-completion"
+            Invoke-Expression $other | ForEach-Object {
+                [System.Management.Automation.CompletionResult]::new($_, $_, 'ParameterValue', $_)
+            }
+    }
+    ```
+
+2.  Open the PowerShell profile (`code $profile` or `notepad $profile`) and add the line:
+
+    ```bash
+    & path/to/autocomplete/geth.ps1
+    ```
+
