    1 zstdgrep(1) -- print lines matching a pattern in zstandard-compressed files
    2 ============================================================================
    3 
    4 SYNOPSIS
    5 --------
    6 
    7 `zstdgrep` [*grep-flags*] [--] _pattern_ [_files_ ...]
    8 
    9 
   10 DESCRIPTION
   11 -----------
   12 `zstdgrep` runs `grep (1)` on files, or `stdin` if no files argument is given, after decompressing them with `zstdcat (1)`.
   13 
   14 The grep-flags and pattern arguments are passed on to `grep (1)`.  If an `-e` flag is found in the `grep-flags`, `zstdgrep` will not look for a pattern argument.
   15 
   16 Note that modern `grep` alternatives such as `ripgrep` (`rg`) support `zstd`-compressed files out of the box,
   17 and can prove better alternatives than `zstdgrep` notably for unsupported complex pattern searches.
   18 Note though that such alternatives may also feature some minor command line differences.
   19 
   20 EXIT STATUS
   21 -----------
   22 In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
