How do I list 'WORDS' containing a specific character? awk,sed,grep?
 
I have a large file containing thousands of lines, I want to list only strings containig "::".

File example:
Data::Compare 1.22 (1.2101 < 1.22)::
Data::Dumper::Concise 2.020 (1.100 < 2.020)
Hash::Merge 0.12 (0.10 < 0.12)::
Path::Class 0.18 (0.16 < 0.18)::
Service-now INC10056109 Install Perl Sort::Topological module Primary 0.02 5.8.8, 5.14.0 TESTING ::
String::Escape 0::
String::Escape 0::
Data::Compare 0::
----------------------
Expected output:
Data::Compare
Data::Dumper::Concise
Hash::Merge
Path::Class
Sort::Topological


How can I achieve it?

What about the line starting with Service? It does contain :: Or the one starting with Path?
What's wrong with it?
You need to be more specific

No matter how the line starts or ends, all I need is list of words containing '::' in it.

Try:
Code:
awk '$1 ~/::/ {print $1}' file

My solution above may work or may not. It's not exactly what I think you're after.

Is that what you want?
Code:
Data::Compare
Data:umper::Concise
Hash::Merge
Path::Class
Sort::Topological
String::Escape
String::Escape
Data::Compare

Many thanks.. That is exactly what I wanted. :)

What about that:

Code:
awk '{for (i=1;i<=NF;i++) if ($i ~/[a-z]::/) print $i}' file

Please note that the solution from post #4 will NOT give you the output from post #5
Try the solution from post #7

How about a little gem (pun):
Code:
ruby -ne 'puts $_.scan(/(\w+(::\w+)+)/)[0][0]' file

thank you all

Code:
$ grep -Eo '\b[^ ]+::[^ ]+\b' inputfile.txt
Data::Compare
Data:umper::Concise
Hash::Merge
Path::Class
Sort::Topological
String::Escape
String::Escape
Data::Compare
