Deleting string within a file that finishes with .log

Hello,

This is my first post. Nice forum!

I have a file trls.results
small exemple of content (actually the file can be very big):
./security/htaccess.htm ./security/ipcount.log ./adhoc/sql/datamod06.sql

So there is 3 paths to 3 different files... I want to remove every string that has a ".log" in it...

After manipulation, it should look like this:
./security/htaccess.htm ./adhoc/sql/datamod06.sql

End results: It's important to keep all inline with 1 space between since I will be adding them to array after...

TO do this... Should I use sed, tr, vi with search and replace, awk ? I want to keep it as simple as possible.

Any Ideas!?!?

The server is a HP-Unix.

Thanks
jake

Works like a charm...

I will research this part 's/ [^ ]+\.log//g' in order to understand it..

Thanks

There is one issue with it though. It will not delete .log entry if it is first one in the line, like:
Code:
./security/ipcount.log ./security/htaccess.htm ./adhoc/sql/datamod06.sql

If you want, I can come up with a fix to that Smilie

sed

Code:
sed -e 's/ [^ ]*\.log//g' -e 's/  / /g' -e 's/^ //' file

To modify file in place
Code:
sed -i -e 's/ [^ ]*\.log//g' -e 's/  / /g' -e 's/^ //' file

If -i option isn't available, you can redirect outpu to a file.

both (perl and sed) works but like you said both won't delete .log entry if it is first one in the line.

It would be greatly appreciate it if you help me with a fix for that...

Thanks
