sed question - replacing param values
Hello, Do you have any idea why the below sed command is also replacing the value of "PARAMETER2" instead of just "PARAMETER" in file1 ? Code:
% parameter=PARAMETER
% new_value=2
% cat file1
PARAMETER=1
PARAMETER2=1
% cat file1 | sed s/[^${PARAMETER}=]*$/${new_value}/1
PARAMETER=2
PARAMETER2=2
Thanks. |
