The `posix-cd` program

+ +

+posix-cd changes the current working directory to a +given directory, then executes a program. +

+ +

Interface

+ +

+     posix-cd dir prog...
+

+ +

+posix-cd changes the current working directory to dir +according to the +POSIX +specification for a cd external utility. Then, if prog... is +not empty, it execs into it. +

+ +

Notes

+ +

posix-cd is only available when execline has been configured +with the --enable-pedantic-posix option, and in this case, the +cd binary is a symbolic link to it.
posix-cd fully conforms to the +POSIX +specification. When prog... is not empty, the behaviour of a +cd utility is not specified by POSIX, so posix-cd extends +the spec to be actually useful and usable in an execline program with the same +interface as the regular execline cd command.
Nobody ever executes or needs the external version (i.e. not a shell +builtin) of the POSIX cd command. Compared to the regular execline +cd, posix-cd is uselessly bloated and slow. +The only reason it exists is that some distributions refuse to package +execline correctly unless it is strictly POSIX-compliant; the +--enable-pedantic-posix configure option is there to appease them.
