 DESCRIPTION

The name egrep is an obsolescent version equivalent to grep -E.

A command invoking the egrep utility with the -e option specified is equivalent to the command:

grep -E [ -c| -l][-inv] -e pattern_list [file...]

A command invoking the egrep utility with the -f option specified is equivalent to the command:

grep -E [ -c| -l][-inv] -f pattern_list [file...]

A command invoking the egrep utility with neither the -e nor the -f option specified is equivalent to the command:

grep -E [ -c| -l][-inv] pattern_list [file...]
