i'm just wondering how can we use awk to do exact matches.
for eg
$ cal 09 09 2009
September 2009
Su Mo Tu We Th Fr Sa
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30
$ cal 09 09 2009 | awk '{day="9"; col=index($0,day); print col }'
17
0
0
11
20
0
8
0
As you can see the above command outputs the index number of all the lines that contain the string/number "9", is there a way to make awk output index number in only the 4th line of cal output above.??? may be an even more elegant solution?
I'm using awk to get the day name using the cal command. here's the whole line of code:
$ dayOfWeek=$(cal $day $month $year | awk '{day='$day'; split("Sunday Monday Tuesday Wednesday Thursday Friday Saturday", array); column=index($o,day); dow=int((column+2)/3); print array[dow]}')
The problem with the above code is that if multiple matches are found then i get multiple results, whereas i want it to output only one result.
Thanks!
