How to trim a string in unix shell script
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?
