I have downloaded some log files from my server which I want to search for a specific string for debugging purposes. All of them have the .log extension.
The problem is that one file has the plain text document (text/plain) mime type while the other has the Binary (application/octet-stream) mime type.
I can open the plain text document (text/plain) mime type log file in a text editor as plain text but the other I can't since it's in binary.
How can I view the binary .log files with application/octet-stream mime type?

From this answer in What makes grep consider a file to be binary?
If there is a NUL character anywhere in the file, grep will consider it as a binary file.
There might a workaround like this cat file tr -d '000' yourgrep to eliminate all null first, and then to search through file.
I first tried it with one file in a test directory:
And the result, a plain text document (text/plain) text mime file.
Then since I am working with multiple files, I tried running the same command for multiple files in a directory: Download boruto samehadaku.

And awesome, all my log files are now in a readable format!! :)
Based on your own answer, you seem to be referring specifically to searching files using grep, rather than to changing a file's mime-type - see What is the XY problem?.
If grep is simply misidentifying the files based on null bytes, then you can use the -a or --binary-files=text options to tell grep to treat them as text regardless, as described in the manual pages:
