Shell Programming and Scripting

I am reading a string like $/folder1/folder2/filename from a file
And I am storing it in a variable say $path.
I want to store the path within single quotes in order to use the path within a command.
if i set like path="'"$path"'"
echo $path
It is printing like ' $/folder1/folder2/filename'
( instead of '$/folder1/folder2/filename'). There is a space between in the first quote and $. How to avoid this space.Is there any trim function?

Code:

$
$ x="          $/folder1/folder2/filename"
$ x="'`echo ${x## }`'"
$ echo $x
'$/folder1/folder2/filename'
$
$

Code:

x="'${x##* }'"

Thanks for the quick reply. But i face a different issue if i use
current_path="'${current_path##* }'"
if current_path="$/Main_folder/Sub folder/Release R3.0/filename"
then it sets current_path with "R3.0/filename" instead of "$/Main_folder/Sub folder/Release R3.0/filename". (I think this is becoz of the space between Release and R3.0)Can u pls explain me the meaning of "current_path##* " and tell me what has to be done to take the full path

Code:

x="'$(echo ${x#[ ]*})'"

Parameter Expansion

Code:

x="'$(echo $x)'"

would work but only for file names with single spaces, and it may give unexpected results if there are unusual characters in the name...

Code:

until [ "$x" = "${x# }" ]; do
  x=${x# }
done
x="'$x'"

Thanks a lot:-)
