File Renaming

Lots of programs are available to use...

---
"mved" is a shell script basied on sed.

    mved =.01 =

  Script works, but is a little kludgy in some situations due to the
  messy conversions into sed regular expressions.  It is however simple
  and easy to use in most situations, compared to other solutions below.

---
"mv_perl"
  https://antofthy.gitlab.io/software/#mv_perl

    mv_perl 's/\.01$//' *.01

  This perl solution also allows you to is complex formulas...
  For example this will reformat ALL the numbers in a filename to
  width $w with leading zeros (using "sprintf()" ).

    mv_perl 's/\d+/sprintf "%0*d", $w, $&/eg'   *[0-9]

  These formulas can are often pre-defined in the command and can
  be accessed by renaming (or symlinking) the script to matching names.
  For example the above formula can be used if you rename (symlink) the
  script so it is called as "mv_renum".

---
"mv_renum"
  https://antofthy.gitlab.io/software/#mv_renum

  A more controlled version to the previous perl one above for handling numbers
  in filenames.  Basically it will only replace the first in filenames (-l for
  last number in filename).

  If renamed to "mv_reseq" it will remove gaps in number sequence, with
  controls the start and increment of the numbering, and can even reverse the
  numerical order of the files.

  The script ensures than numbers do not clash or overwrite each other.  If
  there is a filename clash, it initially assumes that file will be renamed
  later, and will try again to see if the destination file was renamed.
  This is especially important when incrementing numbers by 1 or reversing the
  number order.

---
"rename"

  There is a perl version (ubuntu) like "mv_perl" above
    rename 's/\.01$//' *.01

  But there is also a "util-linux" version (pure string replacement)
  Which is what is used on fedora and redhat machines.
    rename .01 ''  *.01

  Because of this multiple version availablility, using "rename" script
  is NOT recommended.

---
A bash solution (Remove ".01" from filename...

   for i in *.01; do mv "$i" "${i%%.01}";

File name editing...

For a whole directory it can be easier to create a script in vim

  ls > files.txt
  vi files.txt
    :%s/.*/mv -i & &/g
    :%s/.JPEG$/.jpg/g
    :wq
  # the resulting shell script can be visiually checked!
  bash files.txt

---
vidir - edit directories and filenames

  Small program to place a numbered directory of filenames in vim.

  You can edit the filenames and on exit it will rename all files as
  you have edited, linking names to the reference number in the file.

---
vim-rename

  A older directory editor like "vidir".

  https://github.com/qpkorr/vim-renamer

---
Vim File Explorer

  vim {directory}

    'R' to rename
    'D  to delete

---
For a single name.. you can replace the "mv" command with a bash function that
lets you edit a filename, if only one argument is given.

  function mv() {
    if [ "$#" -ne 1 ] || [ ! -e "$1" ]; then
      command mv "$@"
      return
    fi

    read -ei "$1" newfilename
    command mv -v -- "$1" "$newfilename"
  }
