.inputrc

Make Tab autocomplete regardless of filename case

set completion-ignore-case on

List all matches in case multiple possible completions are possible

set show-all-if-ambiguous on

Immediately add a trailing slash when autocompleting symlinks to directories

set mark-symlinked-directories on

Use the text that has already been typed as the prefix for searching through commands (basically more intelligent Up/Down behavior)

"\e[B": history-search-forward
"\e[A": history-search-backward

Ctrl left, ctrl right for moving on the readline by word

"\e[1;5C": forward-word
"\e[1;5D": backward-word

Do not autocomplete hidden files unless the pattern explicitly begins with a dot

set match-hidden-files off

Show all autocomplete results at once

set page-completions off

If there are more than 200 possible completions for a word, ask to show them all

set completion-query-items 200

Show extra file information when completing, like ls -F does

set visible-stats on

Be more intelligent when autocompleting by also looking at the text after the cursor. For example, when the current line is "cd ~/src/mozil", and the cursor is on the "z", pressing Tab will not autocomplete it to "cd ~/src/mozillail", but to "cd ~/src/mozilla". (This is supported by the Readline used by Bash 4.)

set skip-completed-text on

Allow UTF-8 input and output, instead of showing stuff like $'\0123\0456'

set input-meta on
set output-meta on
set convert-meta off

Use Alt/Meta + Delete to delete the preceding word

"\e[3;3~": kill-word
