Hi
I just want to copy the file name from the input file. Below is the code I have used but the answer comes with quotation .

$ cat test.sh
file_name=\'$1\'
echo $file_name

$ sh test.sh grants.dat
'grants.dat'

How do I remove the quotation

Thanks

Remove the escaped single-quotes.

file_name=$1

Removing th quotation is NOT solving the problem
