Question

Unix Shell script to count repeated 5th column value ( sed awk grep )

Asked by: sunhux

Hi,

I have a file with some sample lines as follows :

19753313 found in platter 3296
19753677 found in platter 3296
19841250 found in platter 3296
19858947 found in platter 3296
119923782 found in platter 3296
339179 found in platter 3298
18452855 found in platter 3298
18458688 found in platter 3298
18462255 found in platter 3298
8466573 found in platter 3298
18472719 found in platter 3298
19342755 found in platter 3302
19345699 found in platter 3302
19347692 found in platter 3302

I need a script to read the above file that will give me an output file as follows :
platter 3296 has 5 records
platter 3298 has 6 records
platter 3302 has 3 records

Basically I need to find out for each platter (ie 5th column value), how many records
 are on it.

Currently I can see that the file is sorted by platter number but I can't be certain this
is the case as I've only viewed the first few hundred lines of this input file (there
are thousands of lines in it)
