Command and error:
Code:
sed -i "1s/$/"$VAR"/" Input_file 
Error: sed: -e expression #1, char 20: unknown option to `s'

Hi Singh, I tried your three fixes and didn't work

Hi Greet sed, yes that is not my expected out, I have given my expected output above (tried with escap "\" and didnt work out) and want to edit in a file, I want to add the
Code:
$VAR

value in end of the first line
You have too many quotes (leaving the expansion of $VAR unquoted. Change:
Code:
sed -i "1s/$/"$VAR"/" Input_file

to:
Code:
sed -i "1s/$/$VAR/" Input_file
