Does mac osx supports the “2>&1” syntax to redirect stderr?
In other words, does the following line of code work as expected in mac
osx?
output = some_command 2>&1

As long as you use bash instead of tcsh, yes.
bash -c ’ output = some_command 2>&1
; echo “$output” ’
Notice than nowdays we can use $(some_command 2>&1) instead of the
backquotes, which is nice because you can nest them:
bash -c ’ msg=$(printf “%dnd result = %s” $(( 1 * 2 * 3 * 7 )) “$(echo
“Do not panic”)” ) ; echo “$msg” ’
42nd result = Do not panic
Or use chsh to switch to bash:
