Grep

[debigokan]

I want to extract the same or repeating lines as Grep.

For example:
4.2.2.4
4.2.2.4
4.2.2.4
1.1.1.1
2.2.2.2
1.1.1.1
3.3.3.3
4.2.2.4

It must be just one address from an ip address. How can I do that ?

If these addresses are in file "name", try

Code: Select all

sort name | uniq -d
