One nice way to save space in your filesystem is by running strip ( 24.13 ) on directly-executable (binary) files. You'll probably think of running it recursively with find ( 17.2 ) . Be careful. On some operating systems, using strip on a setuid file ( 1.23 ) will strip the setuid bit; the program won't be setuid anymore. It's best to tell find to skip setuid and setgid files. For instance, the command below finds all world-executable files ( 17.15 ) that are not setuid or setgid ( 17.16 ) :
%find . -type f -perm -0001 ! -perm -4000 ! -perm -2000
...
Other files that shouldn't be stripped include the UNIX kernel (like /vmunix ) and files that programmers need to debug.
