We need to know how many times the string was found, but grepreturns a valuetelling us only if it matched zero times or many. To get around this, we store the output in a file, which will have one line per match, then count the lines in the file. The word count command, wc, has white space in its output, separating the number of lines, words, and characters in the file. We use the $(wc -l $temp_file)notation to extract thefirst parameter from the output in order to set the linesfoundvariable. If we wanted another, later parameter, we would use the setcommand to set the shell s parameter variables to thecommand output. We change the IFS (Internal Field Separator) to a comma so we can separate the comma-delimitedfields. An alternative command is cut. find_cd() { if [ $1 = n ]; thenasklist=nelseasklist=yficdcatnum= echo -e Enter a string to search for in the CD titles c read searchstrif [ $searchstr = ]; thenreturn 0figrep $searchstr $title_file > $temp_fileset $(wc -l $temp_file) linesfound=$l86Chapter
