          Use bash parameter expansion:



          zip_file="${filename}"
          new_name="${zip_file%.*}"



          • new_name will contain the name test if the zip_file has test.zip



          • If the zip_file has test.foo.zip, new_name will have test.foo, if you want only test out of test.foo.zip use:



            new_name="${zip_file%%.*}"

          • This seems to include part of the path. I just want the file name. eg NOT ./Somefolder/Somefolder/FilenameminusExtn but FilenameminusExtn

          • @JohnnyBizzle With due respect why would you give the filename as test.zip, why don't you include the path or mention that there would be path before the file name? Please edit your question and add some examples (be precise) and your desired output (be precise)..

          heemayl is still right: example:



          full_path=/foo/bar/baz.zip
          file_name="${full_path##*/}"
          name="${file_name%.*}"

            Using sed:



            zip_file="$(<<< "${filename}" sed -r 's/^(.*)..*/1/')"




            • zip_file="$( [...] )": assigns the stdout of an invoked subshell to the variable zip_file as a string


            • <<< "${filename}" [...]: redirects the content of the variable ${filename} to the invoked subshell's stdin as a string


            • sed -r 's/^(.*)./1/': edits the content of the invoked subshell's stdin using extended regular expressions, by matching the whole string and replacing it with the substring matching every character from the start until the last dot
