Rename file with first line of file

[Elender]

Is it possible?

For example the first line of file contains a sentence wich uses all type of characters, even invalid ones like \ / : * ? " < > | which should be ignored.

For more details: I'm talking about txt files.

Greetings Elender.
Im not can do this in javascript, but thinking certainly its to be possible, since the exiftool does this with perl. The perl has readpipe() function, so maybe the javascript has related function() to conduct in similar design? If its not to be illegal, I can post exiftool solution, but not if the javascript already does this.
