i really don't understand your probl
assumed this is true: two files with same name and same file content try something like: Code:
#!/bin/sh
mkdir -p ${d3:=third-directory} ¦¦ exit 1
cmpme()
{
for one in `ls $1`
do for two in `ls $2`
do case $one in $two) ;; *) continue;; esac
cmp $1/$one $2/$two ¦¦ continue
# one and two have the same NAME and CONTENT
[ -f $d3/$one -o -d $d3/$one ] && continue # $one still present in $d3, Q should one and two be removed ?
mv $1/$one $d3
rm -rf $2/$two
done
done
}
# main program
cmpme dirone dirtwo
cmpme dirtwo dirone
exit 0
NOT TESTED, just an idea there is sure a better way, explain the probl.
