appending line with characters

[arunrr]

Hello,

I have the following input file...

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

Basically it is a monthly calendar (June 2011). I need to fill the blanks with 'X', meaning...

X X X 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 X X

I top row is straight forward, as the following does it...

sed 's/ / X /g'

Please help with the bottom row.

Thanks
Arun

Hi

Better tell us your goal so we can help with the solution.

This transformation seems quite pointless for now. What should happen next after you add the X's ?

Thanks for your reply. I am building an interactive cricket calendar. Here is a template...

The cells where there is no date ('X') is shaded as shown.

Thanks,
Arun

Hi,

This is done. Used the following...

cat input | sed '/^$/d' | awk '{if (NF<7) for(i=NF;i<7;i++) $0=$0" X"; printf $0"\n"}'

Thanks
AR

Hi

Well, it can be solved with [tt]sed[/tt] alone :

sed 's/   / X /g;:b;/.\{20\}/!{s/$/  X/;bb}' input

[gray]# or[/gray]

sed 's/   / X /g;:b;s/^.\{,19\}$/&  X/;tb' input

But I still have the feeling of walking the wrong way.

If this is for a web page you may be better of performing the whole task on the web server (perhaps with a PHP script)

I think further information is required before the best solution can be advised.

Hi

I agree.

I would add that a database would be a better storage for the calendar data. Searching and statistical queries would be easier to add later. Also web based calendars usually have different overview levels : year, month, week. Those would be also easier to achieve with PHP and SQL.
