Bash – Make Bash autocomplete guess the closest approximation

autocompletebash

I have a somewhat uncomfortable keyboard on my laptop, resulting in that I sometimes misspell things in Bash and when pressing Tab for an auto-completion nothing happens.

Is it possible to have Bash guess what I meant to type, by for example when wanting to change directory to Documents and then mistyping cd ocum[TAB], given no other folder beginning with "ocum" is present, Bash interprets it as cd Documents/ since it is the closest possible action to do?

Or is this idea terribly complicated to achieve?

On github there's an 11K fuzzy_bash_completion script that appears to match some of the spec:

For example:

mkdir pizza
mkdir jazz
cd zz<TAB>
# displays `pizza' and `jazz'
rm -r jazz
cd zz<TAB>
# completes the word `pizza'

Bash – How to Enable Autocomplete in SSH Session

In short: source /etc/bash_completion should do the trick (run it in the shell within the SSH session).

Long story: in order for bash completion to work, you have to tell bash how to complete each command's arguments. This requires a long sequence of invocations of the bash built-in command complete; therefore, they are usually collected in a separate script (or several ones in /etc/bash.complete.d/*) that loads them all.

Being a regular shell script, you can always load the bash_completion in any shell startup script (~/.bash_profile, ~/.bash_login, ~/.bashrc)

Bash – Custom bash autocomplete for git breaks other git autocomplete features

You could use __git_complete (defined in git-autocompletion.bash) to install your own function, and have your function fall back to the original function. Possibly like this:

function _ptid_git_complete_()
{
  local line="${COMP_LINE}"                   # the entire line that is being completed

  # check that the commit option was passed to git 
  if [[ "$line" == "git commit " ]]; then 
    # get the PivotalTracker Id from the branch name
    ptid=`git branch | grep -e "^\*" | sed 's/^\* //g' | sed 's/\-/ /g' | awk '{ print $(NF) }'`
    nodigits=$(echo $ptid | sed 's/[[:digit:]]//g')

    if [ ! -z $nodigits ]; then
      : # do nothing
    else
      COMPREPLY=("-m \"[#$ptid]")
    fi
  else
    __git_main
  fi
}

__git_complete git _ptid_git_complete_
