If you installed some packages outside yum, not from repo’s, finding it using yum won’t yield much results.
# yum search lin_* No matches found
I know its installed just not where … Getting a list with installed rpm’s (from yum and not-yum) :
now just to filter out what I need :
rpm -qa |grep lin_*
[[email protected] ~]# rpm -qa | grep lin_* selinux-policy-3.13.1-60.el7.noarch libselinux-utils-2.2.2-6.el7.x86_64 selinux-policy-targeted-3.13.1-60.el7.noarch libpipeline-1.2.3-3.el7.x86_64 libselinux-2.2.2-6.el7.x86_64 readline-6.2-9.el7.x86_64 libnfnetlink-1.0.1-4.el7.x86_64 linux-firmware-20150904-43.git6ebf5d5.el7.noarch lin_tape-3.0.1-1.x86_64 hardlink-1.0-19.el7.x86_64 util-linux-2.23.2-26.el7.x86_64 libselinux-python-2.2.2-6.el7.x86_64
I was searching for lin_tape-3.0.1-1.x86_64; (tape related stuff) Getting more info : rpm -qi
[[email protected] ~]# rpm -qi lin_tape Name : lin_tape Version : 3.0.1 Release : 1 Architecture: x86_64 Install Date: Fri 23 Oct 2015 03:54:27 PM CEST Group : System Environment/Kernel Size : 3226031 License : GPL Signature : (none) Source RPM : lin_tape-3.0.1-1.src.rpm Build Date : Fri 23 Oct 2015 03:54:06 PM CEST Packager : IBM Tape SCSI Device Driver Development Vendor : IBM Summary : IBM Tape SCSI Device Driver for Linux Description : The IBM Tape Device Driver, lin_tape, product is a device driver that provides attachment for the IBM TotalStorage and System Storage tape devices to Linux compatible platforms.
I could also check what is in the package, but that I already explained. (rpm -qlp lin_taped.rpm)
Always works : rpm man
Another mystery solved.
