@Pysis Something that is not portable may well work on several system, especially if the shell environment is the same, no worries. By "portable" I mean (cd ...) works in all sh-type shells without using any non-POSIX features. On my machine, with ksh93, neither of popd and pushd exists...

@Pysis Yes, (cd dir && thing) is also much more portable than using pushd and popd.

This Q&A seems to speak of my situation, and may be an improvement on using a surrounding pushd and popd (also > /dev/null if you are trying to avoid the output messages as well), while also keeping the context clean!

@AnthonyGeoghegan Ah, that's true. I always use { ... } for consistency with longer functions though.

Excellent, comprehensive answer. I just thought I'd mention that the function definition only needs one method of grouping commands and the parentheses for the subshell are enough: cdrun () ( cd "$1" && shift && command "$@" ).
