comment How to avoid a useless use of cat when parsing a file?
@ddeimeke, because I didn't remember if it is POSIX or just a common extension. Now I've checked and it is in SUSv2.

comment How to install LuaJIT on FreeBSD without using Gmake?
Why do you constraint yourself to not using gmake? I understand the developers who want more portability than just to gmake, but not a user who don't accept to use prerequisites of the developers. Would you ask the same question for ant or bjam or a 3rd party library?

comment Command to get cpu cores in LINUX IA64
Could you point me where in POSIX /proc/cpuinfo is specified? I've just looked in the SUSV4 and didn't find it.

comment How to avoid “make” redoing a library
@Max13, The principle of make is that it rebuilds files which are not uptodate with respects to their dependencies. I.E. all rules are file names. (Some make variant have a way to indicates that a rule hasn't the purpose to build a file, see .PHONY in GNUmake for instance, but then they are always executed)

Using mget with the basic ftp clients should work for one directory (but not sub directories).

comment Fastest way to determine if two sorted lists contain unique elements
If the OP doesn't want to know which line is present but just that there is one, adding -l should makes grep quit as soon as a match is found without reading the rest of the big file

comment Is using xargs faster than not using it?
Another point is that in the pipe version, the rm and find are working in parallel (at least if there is enough files to remove). I'd not be surprised that some times it helps, sometimes it hinders the performance.
