sed question

sphynx · 04-28-2004, 02:48 PM

Just started with sed. given a file

Fruit Price/lbs
Banana 0.89
Peach 0.79
Kiwi 1.50
Pineapple 1.29
Apple 0.99
Mango 2.29

i want to put a $ in front of all the amounts. there are two tabs between the two columns. anyone know how to put the $ in there? if necessary i could make the colums separated by a single space or one tab, but using two tabs keeps it looking orderly. I can't seem to find anything on how to put a $ in there using sed (and it must be sed).
thanks in advance.

Must be sed = homework? :)

yeah its a lab that we are doing. i have looked around and read the book, and found insert, change, substitute, append... only substitute or change looks like it will actually change the two tabs into two tabs with a $. but i can't seem to find how to specify the tabs. everytime i try i screw up the file.

sed 's/$[0-9]*\.[0-9]*$/$&/' fruit.txt

Seems to work for me :)
