Sometimes we need to get part of the full path of a filename.

I'll use this full path in the examples:

/path/to/you/filename.ext

Say you want only the filename with extension, then you can use "basename":

basename /path/to/you/filename.ext

This results in

filename.ext

Now we can use this is scripts, like so:

~ $ echo $(basename /path/to/you/filename.ext)       

filename.ext
~ $ myfile=/path/to/you/filename.ext                    
~ $ echo $(basename $myfile)            

filename.ext

 

When using variables, you can do some neat tricks as well, if you want just the extension, or just the filename without extension, or a "double" extension (targ.gz for example):

~ $ myfile="example.tar.gz"

~ $ echo "${myfile%%.*}"
example

~ $ echo "${myfile%.*}"
example.tar

~ $ echo "${myfile#*.}"
tar.gz

~ $ echo "${myfile##*.}"
gz

Anyhoo ... hope this is useful to anyone - keeping it here for my own reference as well 😁
