Given file names like these:
/the/path/foo.txt bar.txt I hope to get:
foo bar Why this doesn't work?
#!/bin/bash fullfile=$1 fname=$(basename $fullfile) fbname=${fname%.*} echo $fbname What's the right way to do it?

If you want to retrieve the filename without extension, then you have to provide the file extension as SUFFIX with `basename` command. Here, the extension is “. txt”.
Remove File Extension Using the basename Command in Bash If you know the name of the extension, then you can use the basename command to remove the extension from the filename. The first command-Line argument of the basename command is the variable's name, and the extension name is the second argument.
GetFileNameWithoutExtension(ReadOnlySpan<Char>) Returns the file name without the extension of a file path that is represented by a read-only character span.
You don't have to call the external basename command. Instead, you could use the following commands:
$ s=/the/path/foo.txt $ echo "${s##*/}" foo.txt $ s=${s##*/} $ echo "${s%.txt}" foo $ echo "${s%.*}" foo Note that this solution should work in all recent (post 2004) POSIX compliant shells, (e.g. bash, dash, ksh, etc.).

The basename command has two different invocations; in one, you specify just the path, in which case it gives you the last component, while in the other you also give a suffix that it will remove. So, you can simplify your example code by using the second invocation of basename. Also, be careful to correctly quote things:
fbname=$(basename "$1" .txt) echo "$fbname"
