All, Doing maintenance on the Leap 154 --keep files from packman, duplicate removal is almost impossible as the file naming convention for packman rpms is all over the place. For example, in the past year I have filenames of: pdftk-3.3.2-pm154.10.4.noarch.rpm pdftk-3.3.3-150400.10.pm.6.noarch.rpm pdftk-3.3.3-pm150400.10.4.noarch.rpm pdftk-3.3.3-pm154.10.2.noarch.rpm Where pdftk-3.3.3-150400.10.pm.6.noarch.rpm is the current. However, trying to either sort, or iterate in awk is impossible with some filenames containing "pm154" some just containing "150400" and still others containing "pm150400". That before we get to some with ".pm." and others not. How do you handle parsing duplicates from filenames such as this? also Will the ".. 150400.10.pm.X .." filenames be consistent going forward? -- David C. Rankin, J.D.,P.E.
