```sh
find . -type f -print0 \
| grep -z -- '-min.jpg-[[:alnum:]]*$' \
| while IFS= read -r -d '' f; do
find "$f" -print0 \
| sed -z 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' \
| xargs -0 mv "$f";
done;
```
Or, if you prefer a one-liner:
```sh
find . -type f -print0 | grep -z -- '-min.jpg-[[:alnum:]]*$' | while IFS= read -r -d '' f; do find "$f" -print0 | sed -z 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' | xargs -0 mv "$f"; done;
```
The code above is hardened against malicious, broken, or otherwise non-portable file names. That makes it slightly more complex than necessary.
Never use whitespace in file names. They are non-portable. See POSIX: <https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_282>.
For the hardened version, find(1)'s `-print0` and xargs(1)'s `-0` are common enough that don't need explanation (do an online search). grep(1)'s and sed(1)'s `-z` are less common, but still common enough. read(1)'s `-d ''` is a trick explained here: <https://stackoverflow.com/questions/9612090/how-to-loop-through-file-names-returned-by-find#comment98776168_9612232>.
Here's a simpler version, which you can run if you know your file names are portable:
```sh
find . -type f \
| grep -- '-min.jpg-[[:alnum:]]*$' \
| while read f; do
echo $f \
| sed 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' \
| xargs mv $f;
done;
```
`find . -type f |`:
Find files
`| grep -- '-min.jpg-[[:alnum:]]*$' |`:
Filter those that have interesting file names.
`--` is necessary to avoid interpreting the pattern as an option to grep(1).
`| while read f; do`:
For each path name (each line), store the path name in `$f`, and run the nested commands on it.
`echo $f |`:
Echo the full path name.
`| sed 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' |`:
Remove the part of the file name that we don't like.
`| xargs mv $f;`:
Move the file $f (this was the old path name), to the path resulting of the previous filter.
`done;`:
Have a nice sleep :)

```sh
find . -type f -print0 \
| grep -z -- '-min.jpg-[[:alnum:]]*$' \
| while IFS= read -r -d '' f; do
find "$f" -print0 \
| sed -z 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' \
| xargs -0 mv "$f";
done;
```
Or, if you prefer a one-liner:

Never use whitespace in file names. They are non-portable. See POSIX: <https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_282>. If your file system contains files or directories whose names are dangerous (i.e., contain whitespace), you'll want to use this safer version of the script:
```sh
find . -type f -print0 \
| grep -z '-min.jpg-[[:alnum:]]*$' \
| while IFS= read -r -d '' f; do
find "$f" -print0 \
| sed -z 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' \
| xargs -0 mv "$f";
done;
```
find(1)'s `-print0` and xargs(1)'s `-0` are common enough that don't need explanation (do an online search). grep(1)'s and sed(1)'s `-z` are less common, but still common enough. read(1)'s `-d ''` is a trick explained here: <https://stackoverflow.com/questions/9612090/how-to-loop-through-file-names-returned-by-find#comment98776168_9612232>.

The first snippet is unsafe, and you should only run it if you know that the file names that find(1) will find don't contain any whitespace. If the filenames may contain unportable characters, use the snippet at the bottom of this answer.
```sh
find . -type f \
| grep '-min.jpg-[[:alnum:]]*$' \
| while read -r f; do
echo $f \
| sed 's/-min.jpg-[[:alnum:]]*$/-min.jpg/' \
| xargs mv $f;
done;
```
This should work. Be careful; I didn't try it, so it may need small corrections.

`| grep '-min.jpg-[[:alnum:]]*$' |`:
