Create a folder from a file name
 

I have a files called STMam.bam.

Now i want to create a directory with the same name as the file but it should exclude the .bam extension.

The folder created should be named as STMam.

erm... "mkdir STMam" will do that... if you're after help with scripting or programming, you need to provde more useful information here. the basename tool will probably help you a lot.

Sg like this

While I like the solution I am curious why the escape? A period is not special when globbing nor to the shell so the escape, as far as I can tell, serves no benefit.

FNAME=file.ext
DIRNAME=$(echo ${FNAME/.*/})
echo $DIRNAME will show you directory name


mkdir "${FN%.*}"

DIR_NAME=$(echo ${FILENAME} | awk -F. '{ print $4 }')
mkdir ${DIR_NAME}

I am not sure what you are trying to show here? Well apart from the fact that you are using your own solution and not the example by NevemTeve

Sure, I checked the manual again, dot doesn't have special meaning in this context, so it is unnecessary to escape it. My fault.
