A folder has a huge number of files; each pair of files has the same name but different extensions (.obj and .mtl). I want to make a folder for each pair of files with the same name, then move each pair of files into its matching folder.
File names always have letters; some also have underscores and numbers.

What I need to do is:

A) Read a file name

B) Make a subdirectory with the same name as the preceding file

C) Move the pair of files matching the filename into the matching subdirectory

D) Repeat for the next file

Example:

Files: Big_Column1.obj , Big_Column1.mtl

To be moved into subdirectory: Big_Column1

Here's a quick one-liner to accomplish this. We simply iterate over all files in the current directory using shell globbing (assuming they are the ones you want), create a directory with the name of the file before the period using cut to modify the name (mkdir -p not erroring if the directory already exists), and move the file there. There's not really much to it.

for file in *; do dir=$(echo $file | cut -d. -f1); mkdir -p $dir; mv $file $dir; done

Tested and worked fine

Finding out the all filname and segregating the filenames with same name but with different extensions andsorting out and creating directory and move the files to directory of same name

In below example Big_Column1,Big_Column2 directories are created

for i in `ls -ltrh directorypath| awk '{print $NF}'| awk -F "." '{print $1}'| sort| uniq`; do mkdir $i; yes|cp  $i* $i; done
