its my input file. suppose if i check rice item from input file. it will display the rice item and rice item price also.And if i write non -available item from the file like " sugar " item . it will display the "item is not found".

Answer 1

you can also do it in perl:

perl -F"|" -ane 'BEGIN{$f=0}if(/Rice/){print;$f=1}END{print "not found\n" unless($f)}' your_file

Answer 2

awk -v item=Rice -F "|" "$0 ~ item {i++; total = total + $3}; END { 
if (i>0) print \"item name\",item,\"NO OF ITEMS\",i,\"total amount \",total; else print \"item not found\"}" datafile

output answer:

item name Rice NO OF ITEMS 8 total amount 667

In my program searching for rice. After that searched for pattern matching form input file. Next I used for counting number of rice items, total is used for total amount's of all rice. Initial item is variable, rice is value to assigned to variable item. Finally it displays the item, count of items, total amount of item.

Answer 3

awk -v item=Rice '$0 ~ item { i++; print }
                  END       { if (i == 0) print item " not found" }' data

If you want selected fields, you'll have to identify what each field contains. The 1 is presumably the price? (OK: no, it is fairly unlikely to be the price, but you should not expect us to divine the meaning of the columns in your data; — you should tell us the meanings.) It is not clear whether the item is in field 1 or field 4 or both.

That is not case-insensitive — if you want case-insensitivity, read the manual for your version of awk; it may or may not be possible.
