Top Forums Shell Programming and Scripting Checking whether program is installed Post 302293136 by kduffin on Monday 2nd of March 2009 12:58:31 PM

I don't think I'd recommend using 'which' in order to determine if software is installed - it is only going to see what is in the user's $PATH. rpm or other package managers can identify based on pattern matching.

rpmspec - RPM Spec Tool SYNOPSIS
QUERYING SPEC FILES: rpmspec {-q|--query} [select-options] [query-options] SPEC_FILE ... select-options [--rpms] [--srpms] query-options [--qf,--queryformat QUERYFMT] [--target TARGET_PLATFORM] QUERY OPTIONS The general form of an rpm spec query command is rpm {-q|--query} [select-options] [query-options] You may specify the format that the information should be printed in. To do this, you use the --qf|--queryformat QUERYFMT option, followed by the QUERYFMT format string. See rpm(8) for details. SELECT OPTIONS --rpms Operate on the binary package header(s). --srpm Operate on the source package header(s). SEE ALSO
popt(3), rpm(8), rpmdb(8), rpmkeys(8), rpmsign(8), rpm2cpio(8), rpmbuild(8), rpmspec --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
