Removing character ' from a variable
Hello there,

I have a variable in the form of '/example/file.txt' . I want to remove the ' characters from the beginning and the end so that the my new variable becomes /example/file.txt . How can I do it in a script?

I know this is a fairly easy question, but i wasn't able to implement it.

You can use tr, read the man page.

or

search the forums Smilie

am sure there are multiple threads about the same topic or related to that

using sed to search and replace the character(s)

in your case its going to be searching " ' " and replacing with ""

test example - note that you have to "escape" the ' character or the shell eats it, so to speak. \ = "escape" character
Code:
echo \'hello\'
echo \'hello\'  | tr -d \'
