Manipulate o/p of a Linux command

Hi All,

I am having a heck of a time.

I have runaway processes that are hanging my rpm databases, and I have to issue kill commands.

Presently, I am outputting to a tmp file and manually putting in the kill command. but would like to automate it by the process id.

So, right now I am doing a pgrep -l rpm >/tmp/rpm

the o/p is

302 rpm
305 rpm
313 rpm
with about 9,000 processes behind it.

I would like it to be kill 302 305 313, etc.

if that is not possible.

kill 302

kill 305

any help would be appreciated.

rpmkeys - RPM Keyring SYNOPSIS
rpmkeys {--import|--checksig} DESCRIPTION
The general forms of rpm digital signature commands are rpmkeys --import PUBKEY ... rpmkeys {-K|--checksig} PACKAGE_FILE ... The --checksig option checks all the digests and signatures contained in PACKAGE_FILE to ensure the integrity and origin of the package. Note that signatures are now verified whenever a package is read, and --checksig is useful to verify all of the digests and signatures associated with a package. Digital signatures cannot be verified without a public key. An ASCII armored public key can be added to the rpm database using --import. An imported public key is carried in a header, and key ring management is performed exactly like package management. For example, all cur- rently imported public keys can be displayed by: rpm -qa gpg-pubkey* Details about a specific public key, when imported, can be displayed by querying. Here's information about the Red Hat GPG/DSA key: rpm -qi gpg-pubkey-db42a60e Finally, public keys can be erased after importing just like packages. Here's how to remove the Red Hat GPG/DSA key rpm -e gpg-pubkey-db42a60e SEE ALSO
popt(3), rpm(8), rpmdb(8), rpmsign(8), rpm2cpio(8), rpmbuild(8), rpmspec(8), rpmkeys --help - as rpm supports customizing the options via popt aliases it's impossible to guarantee that what's described in the manual matches what's available. http://www.rpm.org/ <URL:http://www.rpm.org/> AUTHORS
