create multiple folders using existing file names in linux

问题

i have downloaded several pdf files(with various names) and stored them in a specific directory (for example, Downloads/directory1).

i would like to create folders to store these files under the same directory, using the names of the original files, but without the extension pdf.

for example, for a file named maths.pdf, i want to create the folder maths and store the pdf in it.

i made several attempts creating a script using commands as basename and for, but i didn't have any luck.

回答1:

You can do:

Assuming you're getting:

filename='Downloads/directory1/math.pdf'

f="${filename##*/}"
dir="${f%.*}"

mkdir -p "$dir"

will create mathdirectory

回答2:

try with:

  cd Downloads/directory1
  for f in *.pdf; do
     fname=${echo $f | sed "s/.pdf//" }
     echo "Creating directory [$fname]"
     mkdir "$fname"
  done
