sed files

#1 Post by hermie » Sun Sep 07, 2014 12:06 pm

I have noted in looking in my files via Dolphin that several files such as; sedf7joMm; sedTWjX8W show up and cannot be opened by the usual applications. All these files seem to the the same size of l.6 GiB. A window pops up when trying to open them that presents various applications that might be tried, but I can find none that open these files. They are preceeded by an icon that has what looks like 4 windows with the right lower corner turned up with a small yellow symbol in the turned up area that I can not make out what it is. In trying to find out something about them, the only info that turns up for a "sed" search is that: "sed-a non-interactive text editor" that has something to do with large complicated files.

What are these files, can they be safely deleted and can they be prevented from being stored in the file system? Thanks for any insight on this perplexing matter. I am currently using KWheezy distro.

My guess is some app might have created one or more temporary sedxxxxxx files (the last six characters 'xxxxxx' as random characters) and might not have removed them when it was done using them.

Where are they showing up at?

What did they say about those files on the KWheezy Forum?

I did a web search on "open linux sed files" and found this nice tutorial:

I suspect the "sed" they begin with and the sed stream editor don't have anything to do with each other, but is just coincidence. Maybe a screenshot of the icon they show (a link?) plus what directory they are in will tell us a lot--or opening it with a hex editor and looking for text strings.

They seem rather large, too. Maybe they are some sort of memory dumps? Edit: Maybe backups of the system?

I don't think you want to remove these.

At 1.6 GB each, you don't want too many of them accumulating. The root partition of my MX14 install is only 20GB, it would get filled up pretty quickly.

Agreed that they are very large files.
If a program is making them a path for those files might shed some light. And should allow an adjustment to said program that would remove them automatically.

Sed comes handy when working with log files. Especially, large files.
This tutorial includes a lot of helpful examples https://likegeeks.com/sed-linux/
Just use sed and pipe the result to a file to save and that's it.

You realize that this is a 4-year old thread, right?

Usually the only time we see that behavior is when dealing with spammers...

I thought first time posters were not allowed to post links, did we change that?
