zgrep: Output count of lines containing matched pattern in a compressed file.
$ zgrep -c ${pattern} ${path-to-compressed-file}

The "zgrep" command is used to search for a pattern within a compressed file. Here is a breakdown of the command structure:

  • "zgrep": This is the command itself, indicating that we want to search within a compressed file.
  • "-c": This is an option for the "zgrep" command, and it specifies that we want to count the occurrences of the specified pattern. Instead of displaying the matching lines, it will output the count of matching lines.
  • "${pattern}": This is where you should provide the pattern you want to search for within the file. It can be a word, phrase, or regular expression.
  • "${path-to-compressed-file}": This is the path to the compressed file that you want to search within. It should be specified with the appropriate file extension (.gz, .bz2, etc.).

In summary, the "zgrep -c" command allows you to look for a pattern in a compressed file and find out how many times the pattern appears in the file, instead of displaying the matching lines.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
