** Summary changed:
- apt-mark showauto is slow
+ 'apt-mark showauto' and 'apt show' is slow
** Description changed:
- $ time apt-mark showmanual >/dev/null
+ $ time apt-mark showauto >/dev/null
- real 0m0.610s
- user 0m0.544s
- sys 0m0.024s
+ real 0m0.587s
+ user 0m0.552s
+ sys 0m0.016s
When I run the command first time, it is even much slower.
- I could do the job in fraction of a time using dpkg-query and awk.
+ I could do the job in fraction of a time using awk in POSIX shell
+ script:
+
+ auto_file='/var/lib/apt/extended_states'
+ eval $(apt-config shell auto_file Dir::State::extended_states/f)
+ awk '/^Package:/ {
+ pkg=$2
+ getline; arch=$2
+ getline
+ if($2==1) print pkg ":" arch
+ }' "$auto_file" | CL_ALL=C sort -u
+
+ real 0m0.019s
+ user 0m0.008s
+ sys 0m0.000s
+
+ That prints architecture for every package and shows entries in slightly
+ different order, though. And the file could be out of date showing
+ packages that are not installed?!?
+
+ Similarly
+
+ apt show <pkg>
+
+ is slow. (It also shows whether a package is manually or automatically
+ installed.
