       bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a
       regular expression


       bzgrep [ grep_options ] [ -e ] pattern filename...
       bzegrep [ egrep_options ] [ -e ] pattern filename...
       bzfgrep [ fgrep_options ] [ -e ] pattern filename...


       Bzgrep is used to  invoke  the  grep  on  bzip2-compressed  files.  All
       options  specified  are  passed  directly  to  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 grep.

       If bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is  used
       instead  of grep.  If the GREP environment variable is set, bzgrep uses
       it as the grep program to be invoked. For example:

           for sh:  GREP=fgrep  bzgrep string files
           for csh: (setenv GREP fgrep; bzgrep string files)
