date output [solved]

[devries]

I want to have an date output in this format: 2006-03-11

 

How do I do that?

 

The link is: http://files.ad.nl/strips/image.php?strip=...atum=2006-03-11

 

I have:

 

#! /bin/bash

url="http://files.ad.nl/strips/image.php?strip=dirkjan&datum="

printf "${url}$(date)"

 

But that doesn't work.

I did this, but it only works on the positioning of the characters of the url you specified. This was for testing, so you could see it works:

 

echo "http://files.ad.nl/strips/image.php?strip=dirkjan&datum=2006-03-11" | cut -c 57-67

 

and the results:

 

[ian@esprit ~]$ cat test
echo "http://files.ad.nl/strips/image.php?strip=dirkjan&datum=2006-03-11" | cut -c 57-67
[ian@esprit ~]$ ./test
2006-03-11

 

Obviously if the url length changes, you need to change the digits at the end which specify cutting characters from position 57 to 67. Or find a way of getting cut to calculate the position of the date based on a field character. See this example for pulling uid from /etc/passwd:

 

[ian@esprit ~]$ cat /etc/passwd | grep ian | cut -f 3 -d :
500

 

you might be able to get the same to work. To get the gid instead of uid, you change the "3" to a "4" and so on for other info. Actually, I just used that too:

 

[ian@esprit ~]$ cat test
echo "http://files.ad.nl/strips/image.php?strip=dirkjan&datum=2006-03-11" | cut -f 3 -d =
[ian@esprit ~]$ ./test
2006-03-11

 

and works, as there are two equals signs splitting it into 3 parts, so choosing the 3rd part, using delimeter =. If a third equals sign was listed, then the date would be in the fourth field part, and therefore having to change the "3" to a "4" to get it to work.

I want to have an date output in this format: 2006-03-11

 

#! /bin/bash

url="http://files.ad.nl/strips/image.php?strip=dirkjan&datum="

printf "${url}$(date)"

But that doesn't work.

Try this:

 

echo $url`date +%Y`-`date +%m`-`date +%d`

 

or

 

printf $url`date +%Y`-`date +%m`-`date +%d`

[paul]

date +%Y-%m-%d

result = 2006-03-12

[devries]

date +%Y-%m-%d

 

I tried that first because it looked the easist and what do you know... it worked. :D

 

the script now looks like:

 

#! /bin/bash

url="http://files.ad.nl/strips/image.php?strip=dirkjan&datum=$(date +%Y-%m-%d)"

imgname=/home/xxxxx/tmp/dirkjan.jpg

wget -qO $imgname "$url"

echo -n "$imgname"

 

Because komics uses kuickshow to show the actual comic and it needs for the file to have an extension. It's working again now so I hope the newspaper will keep this adress. I hate it when they change things.
