| 33 .SH DESCRIPTION |
| 34 .B xzgrep |
| 35 invokes |
| 36 .BR grep (1) |
| 37 on |
| 38 .I files |
| 39 which may be either uncompressed or compressed with |
| 40 .BR xz (1), |
| 41 .BR lzma (1), |
| 42 .BR gzip (1), |
| 43 or |
| 44 .BR bzip2 (1). |
| 45 All options specified are passed directly to |
| 46 .BR grep (1). |
| 47 .PP |
| 48 If no |
| 49 .I file |
| 50 is specified, then the standard input is decompressed if necessary and fed to |
| 51 .BR grep (1). |
| 52 When reading from standard input, |
| 53 .BR gzip (1) |
| 54 and |
| 55 .BR bzip2 (1) |
| 56 compressed files are not supported. |
| 57 .PP |
| 58 If |
| 59 .B xzgrep |
| 60 is invoked as |
| 61 .B xzegrep |
| 62 or |
| 63 .B xzfgrep |
| 64 then |
| 65 .BR egrep (1) |
| 66 or |
| 67 .BR fgrep (1) |
| 68 is used instead of |
| 69 .BR grep (1). |
| 70 The same applies to names |
| 71 .BR lzgrep , |
| 72 .BR lzegrep , |
| 73 and |
| 74 .BR lzfgrep , |
| 75 which are provided for backward compatibility with LZMA Utils. |
