On my Windows-10 PC, I have installed Ubuntu app. There I'd like to grep on the content of a group of zipfiles, but let's start with just 1 zipfile. My zipfile contains two files: a crashdump and an errorlog (textfile), containing some information. I'm particularly interested in information within that error logfile:
<grep_inside> zipfile.zip "Access violation"
Until now, this is my best result:
unzip -c zipfile.zip error.log
This shows the error logfile, but it shows it as a hexdump, which makes it impossible to launch a grep on it.
As proposed on different websites, I've also tried following commands: vim, view, zcat, zless and zgrep, all are not working for different reasons.
Some further investigation
This question is not a duplicate of this post, a suggested, I believe the issue is caused by the encoding of the logfile, as you can see in following results of other basic Linux commands, after unzipping the error logfile:
emacs error.log
... caused an Access Violation (0xc0000005)
cat error.log
. . . c a u s e d a n A c c e s s V i o l a t i o n ( 0 x c 0 0 0 0 0 0 5 )
Apparently the error.log file is not being recognised as a simple textfile:
file error.log
error.log : Little-endian UTF-16 Unicode text, with very long lines, with CRLF line terminators
In this post on grepping non-standard text files, I found the answer:
unzip -c zipfile.zip error.log | grep -a "A.c.c.e.s.s"
Now I have something to start from.
Thanks, everyone, for your cooperation.
