http://www.unix.com – Hi All, I am trying to run a grep command which creates an output file. Then I will run a java file which take that file and process that. My java file uses other java files and library jars. I have tried below code but I am getting compilation error,it can not find other java files in same directory. Please suggest? Code: grep -e keyword1 test.txt -e keyword2| cut -f 2,5,14 | sort| uniq |awk '{$1=$1;print}' OFS=,> /Users/kmajumder/Documents/Shell/java/com/test/opcomma.xls export CLASSPATH=$CLASSPATH:/Users/kmajumder/Documents/Shell/java/lib/*.jar:/Users/kmajumder/Documents/Shell/j (HowTos)
