No no no, that's really NOT how to use a forum.

all the lines starting with "vi" are to edit a file.

The rest are used to do what they do. refer to standard documentation or maybe actually describe why you want to know this. It's a *very* odd thing to ask with no reason, and I'm sure you would get more useful information if you asked a rational question.

why r u asking such random question...please be specific.....
you are really scaring me.....

this is someone doing network admin, and web proxy admin.
because lot of it is using vi, you have no way of knowing what they did inside those vi sessions, so no way of knowing what they actually did (unless you have a backup to compare those files with).

next time, to get more valuable answers, you should be more specific, just ask one question instead of copying and pasting 30 commands.

and give more context, such as "we think we had an intrusion on our proxy server, and would like to know what may have been hacked"
