[SOLVED] Remove first and last character of string only if they match in shell?

Issue

So I'm basically reading the first line from a file and I want the first and last characters to be trimmed but only if they are equal to a certain character. I'm looking to remove "{" and "}" from a string but ONLY IF THEY ARE THE FIRST AND LAST CHARACTERS RESPECTIVELY.

Input:

{Some_random_data_here, {more data here}, test}  

Output:

Some_random_data, {more data here}, test

Here's the full command I'm using which is able to remove the first one but not the last one.

$(head -n 1 "$filePath" | sed s/^{//;s/}$//)

Solution

Your solution worked when I tested it, I only had to escape the ;.

$ echo '{Some_random_data_here, {more data here}, test}' | sed s/^{//\;s/}$//
Some_random_data_here, {more data here}, test
