So I just found out I can create log files of everything I do in screen (C-a H). Sounds like a nice way to keep track of potential goofs in a particular screen session. However, when I went to try it out the logfile is reported as being a binary file (and can’t be viewed like a regular text as such). So am I missing something? A quick man page looksee and searching Google (and SO) turns up nothing about this.
So my question is: How do I generate plain text log files in screen?
Assuming the answer is “What a noob… how about you try making them? RTFM.” my question becomes: How do I use less to view screen logfiles I’ve created (since less screenlog.0 does not work on a binary file)?
EDIT: So cat works fine but less complains that the file is binary… why?
SOLUTION: as jcomeau_ictx helpfully pointed out, you can view these logfiles fine with cat or more but with less you must add the -r flag less -r screenlog.0
I just found a screenlog.0 on the net; it is plain text, with some escape sequences. Just ‘cat’ the file, you should be able to view it just fine.
[after more checking]
Control-A H is what generates the screenlog on my system. And though ‘cat’ works, you’ll miss a lot of data. Use ‘more’ instead of ‘less’ to interpolate the escape codes.
