Batch convert files while retaining the name
I want to use the following command to convert ebooks from epub format to mobi format:
calibre-convert books/*.epub books/*.mobi
but i want to retain the same file name for all the files.
So book1.epub will create book1.mobi
book2.epub will create book2.mobi after conversion.
is this doable in the command line? or do i have to write a bash script?

( cd books && for file in *.epub; do calibre-convert "$file" "${file%epub}mobi"; done )
The main trick here is ${file%epub} which means "$file with epub at the end removed". This way ${file%epub}mobi translates the extension.
A subshell ((…)) is used so
- the current working directory of the main shell stays intact
- and the
filevariable in the main shell doesn't change.
Any directory that matches *.epub in books/ will be passed to calibre-convert as well. It's up to the tool what it will do with the directory. You probably have no such directory there; but if you do, be warned.
Note: I don't know calibre-convert at all; the syntax in my command is simply derived from your command.

@Tlink It's possible to do this recursively withfindor with**(aftershopt -s globstarin Bash). Formal note though: the example in your question is not recursive and my answer keeps things this way. Substantially changing the question after any answer is published (and upvoted, and even accepted by you) is not a good practice here. In my opinion a separate question will be good, where you explicitly ask for a recursive solution (maybe link to this question to provide context, but even then the new question should be standalone).

@Tlink It's possible to do this recursively with
find or with ** (after shopt -s globstar in Bash). Formal note though: the example in your question is not recursive and my answer keeps things this way. Substantially changing the question after any answer is published (and upvoted, and even accepted by you) is not a good practice here. In my opinion a separate question will be good, where you explicitly ask for a recursive solution (maybe link to this question to provide context, but even then the new question should be standalone).– Kamil Maciorowski
