| .SH DESCRIPTION | ||
| .I Bzcmp | ||
| and | ||
| .I bzdiff | ||
| are used to invoke the | ||
| .I cmp | ||

| program on bzip2 compressed files. All options specified are passed | ||
| directly to | ||
| .I cmp | ||
| or | ||
| .IR diff "." | ||
| If only 1 file is specified, then the files compared are | ||
| .I file1 | ||
| and an uncompressed | ||
| .IR file1 ".bz2." | ||
| If two files are specified, then they are uncompressed if necessary and fed to | ||
| .I cmp | ||

| .SH BUGS | ||
| Messages from the | ||
| .I cmp | ||
| or | ||
| .I diff | ||
| programs refer to temporary filenames instead of those specified. |

| .TH BZGREP 1 | ||
| .SH NAME | ||
| bzgrep, bzfgrep, bzegrep \- search possibly bzip2 compressed files for a regular expression | ||
| .SH SYNOPSIS | ||
| .B bzgrep | ||
| [ grep_options ] | ||
| .BI [\ -e\ ] " pattern" | ||
| .IR filename ".\|.\|." | ||
| .br | ||
| .B bzegrep | ||

| .IR filename ".\|.\|." | ||
| .br | ||
| .B bzfgrep | ||
| [ fgrep_options ] | ||
| .BI [\ -e\ ] " pattern" | ||
| .IR filename ".\|.\|." | ||
| .SH DESCRIPTION | ||
| .IR Bzgrep | ||
| is used to invoke the | ||
| .I grep | ||
| on bzip2-compressed files. All options specified are passed directly to | ||
| .I grep. | ||
| If no file is specified, then the standard input is decompressed | ||
| if necessary and fed to grep. | ||
| Otherwise the given files are uncompressed if necessary and fed to | ||
| .I grep. | ||
| .PP | ||
| If | ||
| .I bzgrep | ||
| is invoked as | ||
| .I bzegrep | ||
| or | ||
| .I bzfgrep | ||
| then | ||
| .I egrep | ||
| or | ||
| .I fgrep | ||
| is used instead of | ||
| .I grep. | ||
| If the GREP environment variable is set, | ||
| .I bzgrep | ||
| uses it as the | ||
| .I grep | ||
| program to be invoked. For example: | ||
|
|
||
| for sh: GREP=fgrep bzgrep string files | ||
| for csh: (setenv GREP fgrep; bzgrep string files) | ||
