<p>hello all,<br></p><p>firstly, i have a particular need to quickly query for package info given a batch of files so, i've tried the following:</p><p>rpm -qf `cat files.list` --nodigest --nosignature</p><p>where files.list contains approximately 650 files. this query took 1s on my machine to complete while repeatedly invoking the same query for each filename took 1 min. however, rpm man page doesn't mention the -f (--file) option can take a list of files so i'm quite hesitant to use this in my script. can i reliably depend on this behavior?</p>
<p>secondly, i'd like to have the package name and the filename used in the query to be printed in the format <package-name>:<filename>, so i've added a --qf '%{NAME}:%{FILENAMES}\n' to the query. this does what i want but it seems like a strange thing to do as FILENAMES is a list and should be enclosed in the [ ] brackets. i've read the doc and my usage should output something similarly to <package-name>: (array) instead. how can i print out the package name and filename properly? thanks alot.</p>
<p>cheers,</p><p>tan</p>
