zegrep:tldr:adb24

The command "zegrep --with-filename --line-number "${search_pattern}" ${filename}" is used to search for a specific pattern within one or multiple files using zgrep.

Here is the breakdown of each component of the command:

• "zegrep": This is the command itself, which is similar to the standard "grep" command. However, it is used to search within compressed files (gzip, compress, etc.) without the need to manually decompress them first.

• "--with-filename": This option instructs zegrep to display the filename alongside each line that matches the search pattern. It helps to easily identify which file the matching line belongs to.

• "--line-number": This option tells zegrep to display the line number of each matching line. It prints the line number alongside the matched line and the filename (if --with-filename option is used).

• "${search_pattern}": This is a placeholder for the pattern you want to search within the file(s). You need to replace it with the actual pattern you are looking for. For example, if you want to search for the word "example", you would replace "${search_pattern}" with "example".

• "${filename}": This is also a placeholder that needs to be replaced with the name of the file or files you want to search within. If you want to search in a single file, you would replace "${filename}" with the actual file name. If you want to search within multiple files, you can provide a list of filenames separated by a space.

So, when you run this command with the correct search pattern and filename(s), it will search for the specified pattern within the file(s) and display the matching lines along with their line numbers and the filename if enabled.
