Counting lines in a file containing exact fields
1999-02-18 10:06:13
Is there a korn shell function to count lines in a file that have one field
thats the same. For example, if my file looks as follows:
server1 NYHO
server2 NYHO
server3 NYHO
server4 RISC
server5 RISC
server6 NYMLB
server7 NYMLB
server8 NYMLB
server9 NYMLB
I want the script to read the file and count up that there are 3 NYHO, 2 RISC,
and 4 NYMLB. However theres a catch, in reality my files will be much larger
than this containing much more than 3 different instances. I don't want to have
to compare each line to the literal (ie. NYHO, RISC or NYMLB) because theres
just too many of them. Is there any easier way?
