how to pass commandline argument include "|" to java program

Question

One of the arguments passed to my java program is like this, ab|cd. Initially, when I run the java program, like this,

$ java className ab|cd

it fails, since | is interpreted in the linux shell as a pipe symbol. So only ab is passed into java program. So I made a second attempt:

$ java className "ab|cd"

This time, "ab|cd" is passed in, but the value includes the double quotes. What the program is really intended to have is ab|cd. How can I pass in the correct value without the quotes?

you can also quote("ab|cd" or 'ab|cd') the commandline arguments — Prince John Wesley

In the command shell, you can escape out characters using the '\' character.

 java className ab\|cd

Try (for Linux):

For Windows:

Try this,

"\" is used inorder to nullify the effect of the characters which have special meanings.

java className ab\|cd
