[solved] Remove last word of a string?


I have a string that may or may not have 4 dots.
The string is actualy a file within a folder, where multiple files are located.

Files may look like:
[root@dell nas]# ls *
creds:  someserver

shares:  someserver.sharefolder
[root@dell nas]#

I want to fill 2 variables, $SERVER and $SHARE.
Obviously either '' or 'servername' should be in $SERVER, while 'sharename' should become $SHARE.

Maybe i could just use another symbol than a dot as filename seperator between $SERVER and $SHARE?
But i nether want to use '-' nor '_' as they might occour in a share- or servername (right?), while i'm not sure how a coma as part of a filename works out.

Please note, the relevant code blocks are the function and the 'else' part.
	GetServerShare() { # SERVER | SHARE
	# Pass either Server- or Sharename
	# Returns SERVER/SHARE (list if multiple)
		# Look if ITEM is SERVER
		servers="$(ls $CONFIG_CREDS|grep $1)" 
		# Look if ITEM is SHARE
		shares="$(ls $CONFIG_SHARES|grep $1)"

		# The grep \. should print out only server.share item,
		# given the assumption the user has set them up already,
		# while grep $1 will reduce the list to match provided argument/string
		output="$(printf $servers $shares |grep \.|grep $1)"
		for ITEM in $output;do
		    printf "$ITEM\n" # Need code here
....... other code ....
	else	if ( [ $mode = mount ] && [ ! "" = "$(echo $1|grep '/')" ] ) || \
			( [ ! $mode = mount ] && [ ! "" = "$(echo $2|grep '/')" ] )
		then	# Adress contains slashes, thus contains server & share info
			if [ ! $mode = mount ] #|| [ $doEdit ] || [ $doUnmount ]
			then	export	SERVER=$(printf "$2"|sed s,'/',' ',g|awk '{print $1}') \
					SHARE=$(printf "$2"|sed s,'/',' ',g|awk '{print $2}')
			else	export	SERVER=$(printf "$1"|sed s,'/',' ',g|awk '{print $1}') \
					SHARE=$(printf "$1"|sed s,'/',' ',g|awk '{print $2}')
		else	# Its just the IP/NAS or the Share name
			STR=$(GetServerShare $server_info)
			# This export needs to be changed too,
			# if i'd change the sed from / to '.' i'd get only 127 as SERVER,
			# but it would work if the servername was used (but would required changes at /etc/hosts
			export	SERVER=$(printf "$STR"|sed s,'/',' ',g|awk '{print $1}') \
				SHARE=$(printf "$STR"|sed s,'/',' ',g|awk '{print $2}')
			echo $SERVER # DEBUG - debug::
			echo $SHARE # DEBUG - debug:: EMPTY
		# Current 'fix' as the above 'else' in combination with export produces a trailing dot
		[ "${CONFIG_SHARE:${#CONFIG_SHARE}-1}" = "." ] && \

As of now, within that elseblock, i need to split up $SERVER ( and make SHARENAME the $SHARE variable, which is currently empty.

Any ideas?
Thank you in advance

Always right after posting an idea pops up Smilie
I could just replace the dots with spaces (using sed), and then check how many words there are, and use the last word (like for word in line,do SHARE=$word;done) to be used as Variable $SHARE
No better solution comes to mind.

The loop works, though its not elegant, but once all is working, the scripts needs another rewrite anyway.

Assuming your STR will be something like this, you can use something like this
