YUM w/ Perl like Regular Expressions

snmcdonald · 11-27-2011, 09:19 AM

How can I use Perl like regex w/ YUM? I know Debian based package managers use regular expressions by default. I seem to be able to only use "wildcard" and "glob" like search expressions.

The manpage did not give an example. The CentOS and Fedora docs do not give an example and only state:

Quote:

Regular Expressions
Use Perl or Python regular expressions to carry out more complex queries.

Is there a switch/flag I need to activate? Can someone please post an example?

Unfortunately not, it just says "Use Perl or Python regular expressions to carry out more complex queries." without examples.

Code:

yum list | awk '$1 ~ /^openoffice\.org-[^l].*$/ { print $1 }' | xargs yum install

I suppose you could do something similar:

Code:

yum list | perl -ne '/regex/ && print'

It doesn't seem ideal, but it works.
