Receive 2 positional parameters, check if you receive 2 positional parameters (number of positional parameters), check if 1st positional parameter is a valid name of file (file exists), if the file exist, you can assume that it holds a valid AWK program. you can assume that 2nd positional parameter is a valid name of the file with SED program (do not check for its validity). Run from within your script AWK program which name was passed to the script in the 1st positional parameter. input file to be processed by the AWK program is in_AWK. file. save the output of the AWK program to out_AWK. file. Run from within your script SED program which name was passed to the scripts in the 2nd positional parameter. input file to be processed by the SED program is in_SED. file
