+XZGREP(1)                          XZ Utils                          XZGREP(1)

+NAME
+       xzgrep - search compressed files for a regular expression
+
+SYNOPSIS
+       xzgrep [grep_options] [-e] pattern [file...]
+       xzegrep ...
+       xzfgrep ...
+       lzgrep ...
+       lzegrep ...
+       lzfgrep ...
+
+DESCRIPTION
+       xzgrep  invokes  grep(1)  on  files which may be either uncompressed or
+       compressed with xz(1), lzma(1), gzip(1), bzip2(1), lzop(1), or zstd(1).
+       All options specified are passed directly to grep(1).
+
+       If  no file is specified, then standard input is decompressed if neces-
+       sary and fed to grep(1).  When reading from  standard  input,  gzip(1),
+       bzip2(1), lzop(1), and zstd(1) compressed files are not supported.
+
+       If  xzgrep  is invoked as xzegrep or xzfgrep then grep -E or grep -F is
+       used instead of grep(1).  The same applies to  names  lzgrep,  lzegrep,
+       and  lzfgrep,  which  are provided for backward compatibility with LZMA
+       Utils.
+
+EXIT STATUS
+       0      At least one match was found from at  least  one  of  the  input
+              files.  No errors occurred.
+
+       1      No  matches  were  found from any of the input files.  No errors
+              occurred.
+
+       >1     One or more errors occurred.  It  is  unknown  if  matches  were
+              found.
+
+ENVIRONMENT
+       GREP   If  the GREP environment variable is set, xzgrep uses it instead
+              of grep(1), grep -E, or grep -F.
