This is my code, something in the rec_copy() function isn't working properly, the extension named folders are created in the destination folder but the files are not copied there.
#!/bin/bash if [ $# -ne 2 ] then echo "Usage: $0 <source> <destination>" exit fi if [ ! -d $1 ] then echo "Source folder does not exist" exit fi if [ -d $2 ] then rm -r $2 mkdir $2 else mkdir $2 fi extension=`ls -l $1 | grep -v "^d" | awk '{ print $10; }' | sed 's/^.*\.//g'` for f in $extension do if [ ! -d $1/$f ] then mkdir $2/$f fi done rec_copy(){ folder=`ls $1` for f in $folder do dest=`echo "$f" | sed 's/.*\.//g'` if [ -f $1/$f ] then cp $1/$f $HOME/$2/$dest elif [ -d $1/$f ] then rec_copy $1/$f fi done } rec_copy $1 
$10is the correct file name? What if file names contain spaces?
