Hi,

1)How can we list files with filenames starting with "-" ?
2)what happens when "cat xyz > xyz" is given?
3) which file is used to perform start up instructions for vi editor?

With Regards,

Ans 1. use the option -- with any command to deal with files starting with" -"

Ans.2. it wont let you do that !!!!! If it worked somehow then the filesize will become zero.

Ans 3. Global: /etc/vimrc or depends on your instalation
User specific: $HOME/.vimrc

Hi,

How can we list files with filenames starting with "-" ?

I can't able to understand the answer for this question.
Say for example if a directory contains 3 files

anaconda-ks.cfg
vmlinuz-2.4.20
-xyz.log

All these 3 contains "-" at some instance. when I try to list using "ls | grep -", all the 3 files are listed. What I want is to list out only the file "-xyz.log", which contains "-" at the begining. How to use the "ls"
command ?
