How do I count how many times a specific word appear in a file (ksh)?
I have a txt file with this:

Code:
./INV2143244.41006.ps
./INV18182.41006.ps
./INV18182.41008.ps
./INV75508.41006.ps
./INV2147827.41006.ps
./INV1803373.41006.ps
./INV2148121.41006.ps
./INV2151863.41006.ps
./INV43895.41006.ps
./INV446896.41006.ps
./INV78838.41008.ps

And as you can see from the above there are some line with digit 8 just before
Code:
.ps

So I want to count only those lines with digit 8 like
Code:
./INV78838.41008.ps

If I understand your requirement correctly, then below command will do:
Code:
grep -c "8\.ps" file
