bzgrep: Search `stdin` for lines that do not match a pattern.

$ cat ${-path-to-bz-compressed-file} | bzgrep --invert-match "${search_pattern}"

try on your machine

This command is used to search for lines that do not match a specific pattern inside a compressed file.

Here's a breakdown of the command:

cat: This command is used to concatenate files and display their content. In this case, it is used to read the contents of the compressed file.
${-path-to-bz-compressed-file}: This is a placeholder for the actual path to the bz-compressed file. You would need to replace it with the path on your system.
|: This vertical bar symbol is a pipe. It connects the output of the cat command (the content of the file) to the input of the next command (bzgrep).
bzgrep: This command is used to search for a pattern inside a bz-compressed file. It works similar to the grep command but is specifically designed to handle bz-compressed files.
--invert-match: This flag is used with bzgrep to perform an inverted or negative match. It displays lines that do not match the provided search pattern.
"${search_pattern}": This is a placeholder for the actual pattern you want to search for within the file. You would need to replace it with your specific search pattern enclosed in double quotes.

So, by running this command, the contents of the specified bz-compressed file will be read using cat, then bzgrep will search for lines that do not match the given search pattern, and those lines will be displayed as output.
