Title: ed sometimes clears s bit
Post by: rare_j on June 27, 2006, 01:16:11 PM

Sometimes when I use ed to edit a script it clears the 's' protection bit, sometimes it doesn't.

Does anyone know why this is? Also is there a better program that I could use that doesn't mess with the file protection bits at all?

Ed is a very basic program, it does not care at all about protection bits. The bits are changed to ----RWED whenever you save a file.

As a replacement I'd suggest CygnusEd (http://www.vesalia.de/e_cygnused.htm). It is *the* text editor par excellence.

  Ed will only preserve the "S" bit if the name remains EXACTLY the same.

For example, if you have the "s" protection bit on the startup sequence you have to use:

ed S:Startup-Sequence

and not

ed s:startup-sequence

The later will change the upper-case to lower-case and give the file the default "RWED" protection bits.

Thanks - that's been bugging me for ages
