How do I find out which package an app is in?
 

I use pdftest. It's in the poppler package in Slackware, but not in CentOS. I don't know CentOS.

Centos has this very convenient feature:
If that results in too much output (unlikely for this particular example), use wildcards:
In Centos 8 you can use dnf instead of yum. Instead of whatprovides, lazy typers get away with provides.

Same for Fedora (probably dnf only).

Note that it will only discover packages that are in the currently configured repositories.

for me the usual way is to look for <distro package search> on the net. you will quickly find a good answer. Like this: https://linuxhint.com/centos_package_search/

Is that different from 'provides', which 'yum -help' returned, so I already tried. It returns: Which seems unlikely.


returns no matches.

Returns no matches. I guess it doesn't have it. I already built it, but it's vulnerable to upgrades of dependencies, why I wanted a package version.

Thanks to both of you.

do you mean this: https://github.com/codeborne/pdf-test? Or something else?

Are you sure? I don't see it in the file list. There's one utility, pdfdetach, that Slackware ships in xpdf, whereas other distros have it in poppler, poppler-utils or poppler-tools. But I don't see pdftest in the file list of xpdf either. The Poppler project has a test utility, but it's called test-poppler.

I meant pdftotext. My brain failed. I don't have the coronavirus, so I don't have a diagnosis. Apologies. It's in poppler-utils, which isn't a Slackware package, but 'yum provides' returns it, so I should have had it before I asked.
