Re: Can you highlight the difference
grep command is used to search one or more files for particular character patterns. This is used in UNIX operating system. Actually grep command has three versions namely grep,egrep and fgrep. Among this egrep is the slowest and the functinality is similar to that of grep except that egrep supports extended regular expressions.
