Extract files that start with number to a directory-CodePudding

I have many files in a directory that some of them starts with special characters, spaces , number etc. Now I want to find the files that starts with numbers and put them in a directory. Then find the files that starts with spaces and put them in a different directory, and then the same procedure for files start with capitals.

#!/bin/sh

for nfile in *.png ; do

if [ $nfile=^[0-9]*] ; then
   mkdir NUMBERS
   cp `echo $nfile`  NUMBERS

fi
done

CodePudding user response：

You don't need a loop. Do simply:

mkdir NUMBERS SPACES UPPER
cp [[:digit:]]*.png NUMBERS/
cp [[:space:]]*.png SPACES/
cp [[:upper:]]*.png UPPER/

etc.

Like this:

for space

find . -maxdepth 1 -name ' *' -exec cp {} space_dir \;

for numbers

find . -maxdepth 1 -name '[0-9]*' -exec cp {} number_dir \;

etc...
