ok fair enough, filepath.Ext()
agrees:
The extension is the suffix beginning at the final dot in the final element of path
Bash has a few different ways of getting the extension, depending on what you want:
~% FILE="example.tar.gz"
~% echo "${FILE%%.*}"
example
~% echo "${FILE%.*}"
example.tar
~% echo "${FILE#*.}"
tar.gz
~% echo "${FILE##*.}"
gz
It may be a good safeguard to have filename go through filepath.Base() first
return strings.TrimSuffix(filepath.Base(fileName), filepath.Ext(fileName))

@missinglink if I were writing software to handle gzipped files, then it should properly find the name to be
foo.tar
after removing its.gz
extension, so yes the function should returnfoo.tar
. Also, what about users that make files likeFootage from 04.04.83.mp4
? Presumably you don't want this function returningFootage from 04
. Extension should always be logically construed to mean "the last extension."@chmike I hate .tgz because tar and gzip are two different things. Bothers my OCD, and my ability to find all the gzipped files in a directory. 😂 Two extensions totally makes sense to me in this case.
