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 zgrep +is invoked as +.I zegrep +or +.I zfgrep +then +.I egrep +or +.I fgrep +is used instead of +.I grep. +If the GREP environment variable is set, +.I zgrep +uses it as the +.I grep +program to be invoked.
