I would like to collect opinions: For those who desperately wish to have grep, od, tr, xargs in libcmd: Would it be acceptable to bind these built ins to /opt/ast/bin/grep, /opt/ast/bin/od, /opt/ast/bin/tr and /opt/ast/bin/xargs? /opt/ast/bin is a special path (controlled at build time via the SH_CMDLIB_DIR cpp variable; Solaris uses /usr/ast/bin instead) which can enable built ins even if they are not present as files in the file system.

I'm in a wheelchair with grey hair when this happens. We've elaborated the options and came to the conclusion that none will work: External AST grep is too slow, the .paths solution so desperately defended by David and Glenn is not deployable on a site like CERN (b'cause we can't guarantee that nothing else breaks except ksh93 when there is an extra .paths file in /usr/bin) and generally if the default ksh93 builtin doesn't include it the we have to convince every Linux vendor under this Sun to adopt the same patches or deploy our own ksh93 binaries for every single installation at our site. That's possible but costly. The solution for us was to abandon ksh93 and port the affected applications to perl instead. That's ugly but we've left with no other acceptable choice.
