How to fix a bunch of files with a space between the basename + extension e.g. file .pdf

[luckman212]

I was wondering if anyone has a sweet one-liner for scanning over a directory for any files that have a space between the basename and the extension, for example

/path/to/whatever/my nice file .pdf
/another/path/john's resume .docx

I inherited a bunch of these and want to clean them up.

I got as far as finding them with

fd ' \.'

But I wanted to pass an -x mv {...} {...} using placeholders and there doesn't seem to be a way to "grab" just the extension?

Scratched my own itch for now with a shell script

#!/usr/bin/env bash

if [[ -z $1 ]]; then
	cat <<-EOF
	helper script to fix spaced at the end of filenames between the name + extension
	see: https://github.com/sharkdp/fd/discussions/1589
	usage: fd ' \.pdf' -x extfix.sh {}
	EOF
	exit 0
fi

input=$*
basename=$(basename "$input")
dirname=$(dirname "$input")
ext=${basename##*.}
fname_noext=${basename%."$ext"}
fname_trimmed=${fname_noext%% }
final=$dirname/$fname_trimmed.$ext

cat <<EOF
input=         [$input]
dirname=       [$dirname]
basename=      [$basename]
ext=           [$ext]
fname_noext=   [$fname_noext]
fname_trimmed= [$fname_trimmed]
final=         [$final]

EOF

[[ -e $input ]] || exit
[[ -e $final ]] && exit

mv -v "$input" "$final"
