Extract only part of a text just before delimiter '/'?

I need to find all the mime-type of all the files in the folder.I wrote a small snippet like this.

 for i in $(find /home/someFolder -type f);do file -b $i --mime-type;done

This is returning the following output.

text/html
application/msword
application/msword
text/html
text/html
text/html
application/msword
application/vnd.ms-excel

But can i get the extracted information from these output like only html or msword or png.

html
msword
msword

Are there any libraries which I can use to know the detailed information of the file which should include mime type,size,strings inside the file and any other behavioural information.Any suggestions will help.

Solution

  • Do this:

    find . -type f -print0 | xargs -0L1 file -b --mime-type | cut -d/ -f2

    Much faster and safer than your for approach. (Obviously, replace . with the path you want to start your search from.)
