execline
Software
skarnet.org
 The execline-cd program 
execline-cd changes the current working directory to a
given directory, then executes a program.
 Interface 
     execline-cd dir prog...
execline-cd performs a
chdir()
system call on dir, then execs into prog....
 Notes 
 -  By default, execline-cd can also be invoked as cd:
there is a cd program which is a symbolic link to execline-cd. 
-  When execline has been configured with the --enable-pedantic-posix
option, the cd binary is a symbolic link to the
posix-cd binary instead, so a cd command
in an execline script will invoke posix-cd instead
of execline-cd. 
-  Existing scripts that call cd will keep working no matter the
chosen configuration.
