xzgrep:tldr:42533

The command "xzgrep --fixed-strings "${exact_string}" ${path-to-compressed-file}" is used to search for an exact string within a compressed file using the xz compression format.

Here is an explanation of the components within the command:

1. xzgrep: This command is used to search for patterns in compressed files. It combines the functionality of 'grep' (a text search tool) and 'xzcat' (a decompression tool for xz files).

2. --fixed-strings: This is an option for xzgrep that specifies that the search pattern should be treated as a fixed string rather than a regular expression. This means that any special characters within the search string will be treated literally.

3. "${exact_string}": This variable should be replaced with the exact string you want to search for within the compressed file. It could be any sequence of characters.

4. ${path-to-compressed-file}: This should be replaced with the actual path to the compressed file you want to search within. It could be a file with the '.xz' extension.

So, when this command is executed, xzgrep will search for the exact string specified within the compressed file defined by the path provided. If a match is found, it will display the relevant line(s) containing the string.
