Count and print all repeating words in a line
Gurus,
I have a file containing lines like this :
Quote:
GO:0005874 GO:0005634 GO:0007067 GO:0000778 GO:0005876 GO:0005874
GO:0005938 GO:0000776 GO:0007067 GO:0000092 GO:0007067
GO:0043332 GO:0008017 GO:0005737 GO:0008017 GO:0051301 GO:0005737
GO:0005874 GO:0007067 GO:0000555 GO:0005123
Now, number of words in each line varies. My need is, if a word repeats in a line get it printed. Also total number of repeats.
So, the output would be :
Quote:
GO:0005874 1
GO:0007067 1
GO:0008017 GO:0005737 2
Any help would be highly appreciated.
Thanks & Regards

look(1) General Commands Manual look(1)
NAME
look - Finds lines in a sorted list
SYNOPSIS
look [-df] [-tcharacter] string [file]
The look command prints all lines in a sorted file that begin with string.
OPTIONS
Uses dictionary order; only letters, digits, tabs, and spaces are used in comparisons. Searches without regard to case; treats uppercase
and lowercase as equivalent. Ignores character and characters following it in the search string. If you specify look -tC ABCDE, the
string ABCDE would become (in effect) AB, with CDE being ignored. This option is primarily for shell scripts, in which more than one
string is being processed.
DESCRIPTION
If no file is specified, look searches in the system word list /usr/share/dict/words, with the options -df assumed by default.
The look command uses binary search.
The -d and -f options affect comparisons as in sort.
NOTES
In order to use the -f option, you must first sort file with the sort -f command; otherwise, look displays only lowercase items.
If you do not specify -f, but specify a file (such as /usr/share/dict/words) that has been sorted with sort -f, look may not produce any
output.
EXAMPLES
To search a sorted file called sortfile for all lines that begin with the string as, enter: look as sortfile To search the system word list
for all words beginning with smi, enter: look smi
This might result in: smile smirk smith smithereens Smithfield Smithson smithy smitten
FILES
System word list.

Commands: grep(1), sort(1), spell(1)
