[Slackbuilds-users] Very simple way of finding dependency

[Ythogtha]

If you have a git clone of the SBo repository, you could go there and use this
kind of command line :

-> Get all SBo packages requiredby a specified package, here is wxGTK3 :
grep -E "REQUIRE.*wxGTK3" */*/*.info | cut -d. -f1 | rev | cut -d / -f1 | rev

-> Get all the ones installed on your system :
for pkg in $(grep -E "REQUIRE.*wxGTK3" */*/*.info | cut -d. -f1 | rev | \
cut -d / -f1 | rev); \
do ls /var/log/packages/$pkg-*SBo; done 2>/dev/null

/var/log/packages/audacity-2.1.3-x86_64-2SBo
/var/log/packages/codelite-8.1-x86_64-1SBo
/var/log/packages/filezilla-3.27.1-x86_64-1SBo

-> Get only the names by adding at the end of the previous one :
 | rev | cut -d- -f4 | cut -d/ -f1 | rev
It'll show :
audacity
codelite
filezilla

Put that in a script, and there you are :)
