Searching file contents

Command history

# fh - repeat history
fh() {
  eval $( ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}
# fh - repeat history
fh() {
  print -z $( ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}

Replacing eval with print -z will push the arguments onto the editing buffer stack, allowing you to edit the command before running it. It also means the command you run will appear in your history rather than just fh. Unfortunately this only works for zsh. See below for solutions working with Bash.

These have been tested in bash.

}

# fhe - repeat history edit
writecmd (){ perl -e 'ioctl STDOUT, 0x5412, $_ for split //, do{ chomp($_ = <>); $_ }' ; }

To search for windows and show which is currently active, add ftwind somewhere in your path. Then add eg bind-key f run -b ftwind to your tmux.conf.

v

Inspired by v. Opens files in ~/.viminfo

# v - open files in ~/.viminfo
v() {
  local files
  files=$(grep '^>' ~/.viminfo | cut -c3- |
          while read line; do
            [ -f "${line/\~/$HOME}" ] && echo "$line"
          done | fzf-tmux -d -m -q "$*" -1) && vim ${files//\~/$HOME}
}

With fasd.

Suggested by @epiloque

v() {
  local file
  file="$(fasd -Rfl "$1" | fzf -1 -0 --no-sort +m)" && vi "${file}" || return 1
}

Suggested by @mazinbokhari

# fasd & fzf change directory - open best matched file using `fasd` if given argument, filter output of `fasd` using `fzf` else
v() {
    [ $# -gt 0 ] && fasd -f -e ${EDITOR} "$*" && return
    local file
    file="$(fasd -Rfl "$1" | fzf -1 -0 --no-sort +m)" && vi "${file}" || return 1
}

cd

Integration with zsh-interactive-cd.

Fish like interactive tab completion for cd in zsh.

zsh-interactive-cd-demo

Interactive cd

Suggested by @mgild Like normal cd but opens an interactive navigation window when called with no arguments. For ls, use -FG instead of --color=always on osx.

function cd() {
    if [[ "$#" != 0 ]]; then
        builtin cd "$@";
        return
    fi
    while true; do
        local lsd=$(echo ".." && ls -p | grep '/$' | sed 's;/$;;')
        local dir="$(printf '%s\n' "${lsd[@]}" |
            fzf --reverse --preview '
                __cd_nxt="$(echo {})";
                __cd_path="$(echo $(pwd)/${__cd_nxt} | sed "s;//;/;")";
                echo $__cd_path;
                echo;
                ls -p --color=always "${__cd_path}";
        ')"
        [[ ${#dir} != 0 ]] || return 0
        builtin cd "$dir" &> /dev/null
    done
}

autojump

Integration with autojump

like normal autojump when used with arguments but displays an fzf prompt when used without

j() {
    if [[ "$#" -ne 0 ]]; then
        cd $(autojump $@)
        return
    fi
    cd "$(autojump -s | sed '/_____/Q; s/^[0-9,.:]*\s*//' |  fzf --height 40% --reverse --inline-info)" 
}

z

Integration with z.

like normal z when used with arguments but displays an fzf prompt when used without.

unalias z 2> /dev/null
z() {
  [ $# -gt 0 ] && _z "$*" && return
  cd "$(_z -l 2>&1 | fzf --height 40% --nth 2.. --reverse --inline-info +s --tac --query "${*##-* }" | sed 's/^[0-9,.]* *//')"
}

Here is another version that also supports relaunching z with the arguments for the previous command as the default input by using zz

unalias z
z() {
  if [[ -z "$*" ]]; then
    cd "$(_z -l 2>&1 | fzf +s --tac | sed 's/^[0-9,.]* *//')"
  else
    _last_z_args="$@"
    _z "$@"
  fi
}

zz() {
  cd "$(_z -l 2>&1 | sed 's/^[0-9,.]* *//' | fzf -q "$_last_z_args")"
}

Since z is not very optimal located on a qwerty keyboard I have these aliased as j and jj

alias j=z
alias jj=zz

With fz.

It's yet another z integration. In this version, fuzzy search is enabled with tab completion.

fz-demo

With fasd.

Suggested by @l4u and @epiloque

z() {
  local dir
  dir="$(fasd -Rdl "$1" | fzf -1 -0 --no-sort +m)" && cd "${dir}" || return 1
}

Suggested by @mazinbokhari

# fasd & fzf change directory - jump using `fasd` if given argument, filter output of `fasd` using `fzf` else
z() {
    [ $# -gt 0 ] && fasd_cd -d "$*" && return
    local dir
    dir="$(fasd -Rdl "$1" | fzf -1 -0 --no-sort +m)" && cd "${dir}" || return 1
}

Shell bookmarks

Yet another useful application for fzf: shell bookmarks. It looks as follows: cdg_demo

Google Chrome (OS X/linux)

Browsing history

# c - browse chrome history
c() {
  local cols sep google_history open
  cols=$(( COLUMNS / 3 ))
  sep='{::}'

  if [ "$(uname)" = "Darwin" ]; then
    google_history="$HOME/Library/Application Support/Google/Chrome/Default/History"
    open=open
  else
    google_history="$HOME/.config/google-chrome/Default/History"
    open=xdg-open
  fi
  cp -f "$google_history" /tmp/h
  sqlite3 -separator $sep /tmp/h \
    "select substr(title, 1, $cols), url
     from urls order by last_visit_time desc" |
  awk -F $sep '{printf "%-'$cols's  \x1b[36m%s\x1b[m\n", $1, $2}' |
  fzf --ansi --multi | sed 's#.*\(https*://\)#\1#' | xargs $open > /dev/null 2> /dev/null

vs(){
  #List all vagrant boxes available in the system including its status, and try to access the selected one via ssh
  cd $(cat ~/.vagrant.d/data/machine-index/index | jq '.machines[] | {name, vagrantfile_path, state}' | jq '.name + "," + .state  + "," + .vagrantfile_path'| sed 's/^"\(.*\)"$/\1/'| column -s, -t | sort -rk 2 | fzf | awk '{print $3}'); vagrant ssh

Search for academic PDFs by author, title, journal, institution

Search for all pdf files. FZF will match the query against any text found on the first page of the PDF. For instance, one can query for author names, article title, journal, institutions, keywords. It works by extracting the text on the first page of the PDF using pdftotext.
The selected file is then opened by the default pdf viewer.

Requires the pdftotext command line tool. Tested on Ubuntu 17.10 on bash and zsh.

The script is now given at https://github.com/bellecp/fast-p
