How thoroughly do you want to cheat? $ size /usr/bin/perl /bin/bash text data bss dec hex filename 3840 792 16 4648 1228 /usr/bin/perl 923139 22092 60800 1006031 f59cf /bin/bash $ du -sh /usr/bin/perl /bin/bash 16K /usr/bin/perl 932K /bin/bash Gosh, how does the perl interpreter define an entire language core in 16kb??? Pure magic. Naturally, the loadable modules you mention are very significant either way. $ pacman -Qi bash perl Name : bash Version : 5.1.004-1 [...] Installed Size : 8.19 MiB [...] Name : perl Version : 5.32.1-1 [...] Installed Size : 57.63 MiB And, for extras, it turns out most of the size of perl's no-modules interpreter (that ever so tiny 16kb binary) is in $ du -sh /usr/lib/perl5/5.32/core_perl/CORE/libperl.so 3.7M /usr/lib/perl5/5.32/core_perl/CORE/libperl.so $ size /usr/lib/perl5/5.32/core_perl/CORE/libperl.so text data bss dec hex filename 3604395 77020 25352 3706767 388f8f /usr/lib/perl5/5.32/core_perl/CORE/libperl.so Which is indeed much larger than bash (one binary, no libbash.so, whether to count the separate libreadline.so in my vendor configuration is debatable). -- Eli Schwartz Arch Linux Bug Wrangler and Trusted User
