I'm converting a bunch of (Progress) programs for use on linux (previously used on Windows) and I'm looking for a way to grep for program names with both uppercase and lowercase letters, such as "skip_xref.I" or "NO_dt2.i". How can I achieve this?

How could I downcase a non-English string in Ruby on Rails 3 ?

str = "Привет"    # Russian puts str[0].ord   # => 1055str.downcase!puts str[0].ord   # => 1055 (Should be 1087)

I want it to work in Ruby 1.8.7 as well as Ruby 1.9.2.

How do I take a string and convert it to lower or upper case in Ruby?

I am displaying the data from database using the JQGRID to the user and I have an field EMAIL in which I want to display all the data in lowercase even though the email data stored in DB is uppercase.I tried using the formatter and its throwing me some error

Uncaught TypeError: cellvalue.toLowerCase is not a function

Following is the jqgrid code which I am using to load the email.

{    name: "EMAIL_ID",    align: "center",    width: 140,    formatter: case_converter,    search: true},

following is the Formatter function I am using to convert the data into lowercase for that particular cell value.

//Convert Email Id to lowecasefunction case_converter(cellvalue, options, rowObject) {    var email_lower = cellvalue.toLowerCase();    console.log(email_lower);    return email_lower;}

Even though I am using the Standard javascript function I am getting this error.

I'm trying to create a short program that would convert all letters that are uppercase to lowercase (from the command line input).

The following compiles but does not give me the result I am expecting. What would be the reason for this??

Eg) java toLowerCase BANaNa -> to give an output of banana

public class toLowerCase{public static void main(String[] args){toLowerCase(args[0]);}public static void toLowerCase(String a){for (int i = 0; i< a.length(); i++){    char aChar = a.charAt(i);    if (65 <= aChar && aChar<=90){    aChar = (char)( (aChar + 32) );     }    System.out.print(a); } }   

}
