zgrep is a command-line tool that searches the contents of gzip-compressed files for a pattern without decompressing them. Internally it decompresses the file and passes it to grep, so regular expressions and grep options such as -i and -n work as is, and it also handles uncompressed files. It is useful for searching .gz logs accumulated by log rotation; for zip files use zipgrep, and for bzip2 and xz use bzgrep and xzgrep.
