UNIX for Dummies Questions & Answers

i am not able to understand the following code for awk:

$awk -F"|" '{ kount[$3]++}
>END { for (desig in kount)
> print desig,kount[desig] }' emp.list

the input file i.e. emp.list is ::
3432| p.k.agrwal |g.m |sales
4566|g.l.sharma |director|production
3433|r shah | g.m | production
4545|m.manjunath| director| account


the output is ::

g.m. 2
director 2

i specially did'nt understand the action part of awk {kount[$3]++}

Code:

awk -F"|" '{ kount[$3]++}

Split each input record on the '|' character to obtain fields, and on each record take the 3rd field and increase a counter for that field.

Code:

END { for (desig in kount)
print desig,kount[desig] }' emp.list

When done processing the input, iterate over the counter created above, and print the identifyer and it's associated count value.
