Reason being, i was thinking by arranging the variables under the each Columm name such as Title, Price and Author, it will arrange itself neatly. Let me show u what i meant.
Code:
Code:
echo Title Price Author
echo $Title $Price $Author
but for some reason, when i save the results in a variable, the formatting will be gone, instead of displaying the information in a neat columm, it displays the information on one line like the example below :
Code:
Code:
Title Price Author
PersiaFrancePersiaGermany
I tried using cut command but it also gives me the same problem. If i do not assign it to a variable, how am i able to format it to display it in the correct format?
You could do this all in one awk without declaring multiple awk results to shell variables. When using in printf in shell or awk etc., you can use decimal values etc. to format the output so you have fixed widths between the values.
Here an example:
Code:
awk -F: 'BEGIN{printf("%-20s%-20s%-20s\n", "Title", "Price", "Author")} {printf("%-20s%-20s%-20s\n", $1,$2,$3)}' infile
Title Price Author
Persia 42 John
France 50 Mabel
Persia 50 Rach
Germany 60 John
Thanks for the help guys. This question does not have anything to do with the post but i am just curious. i read up about sed command for delete and for it to delete, you need to specify one input.
for example :
Code:
sed '/$Title/d' fruit > fruittemp
but the problem with this is that it deletes entire rows which contain this information.
so i tried putting in another command which will narrow down which row needs to be deleted.
Code:
grep $Title fruit | grep $Author | sed '/$Title/d' fruit > fruittemp
but this also deletes any row which contains Persia as the title. How do i go about narrow down its seach to a specific row using two input and then deleting it?
Thanks again ahmad. I understand how this code works for the most part, but can i ask , what is the"next" command for in the line and what does the "1" stand for.
