'~' is not supported in a vanilla Bourne shell but '$HOME' should
work. Furthermore you should be logged into your home directory, so
omitting it altogether should work.
~/bin/myprog Works in Korn, Posix, bash, etc. but not Bourne
$HOME/bin/myprog Works in all shells
bin/myprog Also works in all shells
This assumes that HOME exists. The first two give meaningful errors
if it doesn't, the third may silently find /bin/myprog. But if HOME
is not there we are just talking about how deep we are getting into
the proverbial.
Things are a bit trickier for '~joeuser'. The alternatives are now
~joeuser/bin/myprog Does not work in Bourne
$HOME/../joeuser/bin/myprog Might work in all shells
../joeuser/bin/myprog Might work in all shells
These assume that all home directories are in the same place and named
after their owner. If you really want to be robust, try something
like this.
JOEUSER=`ypcat passwd | awk -F: '$1 == "joeuser" {print $6}'`
or
JOEUSER=`awk -F: '$1 == "joeuser" {print $6}' /etc/passwd`
then
$JOEUSER/bin/myprog
