index isn't a literal command, it's part of the expr utility or builtin. Since many shells have it as a shell builtin, what features you get may depend on what shell you use.

You could try forcing it to use an external expr by giving expr's absolute path, i.e. /bin/expr

smd-server(1)						 Sync Mail Dir (smd) documentation					     smd-server(1)

NAME
smd-server - sends diffs and mails to smd-client SYNOPSIS
smd-server [--exclude glob] [-v|--verbose] [-d|--dry-run] [--get-mddiff-cmdline] [--stop-after-diff] [--override-db dbf] [--dump-stdin tgt] endpoint mailboxes DESCRIPTION
smd-server needs to know a name (endpoint) for the client (that must not be used by others) and a list of mailboxes (directories). smd-server first calls mddiff(1), then prints on stdout the generated diff. It then accepts from stdin a small set of commands a client may issue to request a file (or parts of it, like the header). smd-server is in charge of committing the db file used by mddiff(1) in case the client communicates a successful sync. OPTIONS
-v --verbose Increase program verbosity (printed on stderr) -d --dry-run Do not perform any action for real -n --no-delete Do not track deleted files --exclude glob Exclude paths matching glob --override-db dbf Use dbf as the db-file --get-mddiff-cmdline Print the command line used for mddiff and then exist --stop-after-diff Send the actions to the other endpoint and exit. If used in conjunction with --override-db, dbf is removed just before exiting --dump-stdin tgt Dump standard input to tgt and exit NOTES
smd-server is a low level utility. You should use higher level tools like smd-pull(1) and smd-push(1) SEE ALSO
mddiff(1), smd-client(1), smd-pull(1), smd-push(1) AUTHOR
