Understanding RPM Tags in Linux
Understanding RPM Tags in Linux
All rpm package comes with certain tags and can be used for better formatting and fetching the output as required by a Admin or day to day basis.
If we wanna see all the tags we can use
rpm --querytags
Some examples for using these tags are as below
1) Finding only name and version we can use
rpm -qa --queryformat "%{NAME} %{VERSION}\n"
2) Make output in better format in above command
rpm -qa --queryformat "%-30{NAME} %-10{VERSION}\n"
3) Find file names in a package with better format
rpm -ql --queryformat "%{FILENAMES}\n" bash
4) Find file names with size
rpm -ql --queryformat "[%{FILENAMES} %{FILESIZES}\n]" zip
5) Find package install date
rpm -q --queryformat "%{NAME} %{INSTALLTIME:date}\n" zip
6) File files in a package and the permissions
rpm -q --queryformat "%{FILEMODES:perms} %{FILENAMES}\n" zip
