Java to shell script
Greetings to all.Firstly I am new to the forum and I am new to UNIX/Linux and shell scripting.I need help from experts over here.I did not go much through this forum thanks to my lack of time.I need your help in converting a java file to a shell script file.I have pasted my code below.Its a standalone file.It gets two arguments from the user as input.If it is Value1 it will call Help and if it is Value2 it will call another functionality.Another functionality will load the data from the folder by iterating through each file.Finally after finding the results they are written in a file and the name of the file is finally printed.
