 |
|
Hi!
I am fooling around trying to automatically create a google sitemap (an xml file describing the site.)
I am going to generate this with a simple script using a sql dump as input, but i need to trim some stuff before generating.
I have managed to grep/awk out a textfile with page numbers looking like this
('323',
('400',
('243',
...
I have used SED to trim various ( and , but i cant get rid of the single qoute '. The syntax i used to get rid of the ( is sed 's/(//' but as you can see sed uses a ' in the command syntax.
What is the right syntax to get rid of both ' ? I have tried \ " but to no luck. I just want the numbers, nothing else.

You should be able to do sed 's/\'//g' |

sed 's/\'//g' does not work. Just getting a >

This should work in perl:
| Code: | | cat you_file | perl -n -e '/(\d+)/; print $1, "\n"' |

That did it. Double quotes. But with no \ before '. sed "s/'//g"
Will try the perl way too!
Thanks!

Yes, it seem so. It looks like i have to do some perl when converting unix timestamp to ordinary date/time.
