Re: file owner group names
Thinking it over, we could build a caching mechanism and only fall back to stat if we don't have the id in our cache already. Just what I was thinking. PS: ls -l on my machine doesn't truncate the user name.

Jan, But you can use a single stat command to list the property for all your files. Using the format options for the stat call you can tailor the output of the command to suit your needs of parsing. For example, if all you want is group information then you can do something along the lines of: stat --format=%n|%U|%G list of files for example, look at this usage scenario: stat --format=%n|%U|%G base.csv callgraph.dot examples.desktop the output is: base.csv|agarzia|agarzia callgraph.dot|agarzia|agarzia examples.desktop|agarzia|agarzia which is a nice parsable format using cr and pipes. First is the file name, then the owner name, then the group name. I think that a single stat call querying multiple files is easier than ls -l or parsing the detailed files and then checking the /etc/ stuff. :D -- http://www.andregarzia.com All We Do Is Code. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Cheers Monte Well, just to wrap things up, I implemented the caching mechanism with calls to 'stat' to fetch additional user and group names based on the uid/gid from the detailed files.

file owner group names
Hi I'm wondering if there is a way to translate the numeric owner and group returned in the detailed files into the actual names. At present I'm thinking of parsing ls -l but if there's another way to do it I'd be interested to know.

Re: file owner group names
On Unix machines you can lookup - the name of group id by parsing the file /etc/group - the name of a user id by parsing the file /etc/passwd Should be fairly straightforward to read into a variable and turn that into something searchable. In both files, the line delimiter is a newline character and the item delimiter is a colon character - and in both files the id is the third item.

Why not use shell(stat the file) to acquire the information? Hi Andre, It looks like stat has the advantage over ls -l when it comes to displaying the complete user and group name - my user name is janschenkel which is cut down to 8 characters using ls -l so that's not a workable solution. The reason to avoid a shell call to stat is simple: calling it for each individual file in a big folder could prove an expensive operation, while a simple mapping method should suffice to convert 501 to janschenkel when you're already using the detailed files.
