Ashu's questions

I want to write a script which will accept a line of text and should tell me if any of the words are made up of the same letters. Here is an example:

How can you listen if you are not silent?

Here 'listen' and 'silent' are made up of exactly same letters with same frequency.

Any help?

Recently, i'd copied some text from browser and i was too lazy too go and paste it in file by using file explorer. i was wandering if i can paste it directly to the file by just using terminal and some commands. any suggestions?
