I recently installed a minimal version of Fedora 23 Server edition. I use VIM as editor, and I noticed a strange behavior when I edit any text file that is not a new file during.

Whenever I open any existent text file with VIM it is like it performs automatically the keystroke sequence sg<esc>. This is the first time that I see something like this.

NOTE: all of this is happening in an ssh session.

What could be the causes of such a strange behaviour?

If it may be of interest this is the output of vim --version.

$ vim --version

    Rather than linking to pastbin, can you just paste the text result of vim --version into the question. – EightBitTony May 13 '16 at 9:39
  • Sure, I didn't want to bloat the question – Net_Raider May 13 '16 at 9:56

    Can you try running vim without custom initialisations? i.e. with vim -u NONE <filename>. If it fixes the problem, you can try loading different vimrcs individually, with vim -u ~/.vimrc <filename>, vim -u /etc/vimrc <filename> (or wherever your system vimrc's are kept). – Sparhawk May 13 '16 at 10:11
  • @Sparhawk If I do not use any rc file it seems to work ok. Since in my home directory I do not have any .vimrc, It must be something in the /etc/vimrc file right? – Net_Raider May 13 '16 at 11:07
  • I think that's the only other file used in initiation. What's in /etc/vimrc? – Sparhawk May 13 '16 at 11:21
