d0f88fcc 32# We have to find a command that prints all (effective
33# and real) group names (not ids). The known commands are:
34# groups
35# id -Gn
36# id -a
37# Beware 1: some systems do just 'id -G' even when 'id -Gn' is used.
98cfb1fc 38# Beware 2: id -Gn or id -a format might be id(name) or name(id).
39# Beware 3: the groups= might be anywhere in the id output.
f62c0cf2 40# Beware 4: groups can have spaces ('id -a' being the only defense against this)
702a0e5a 41# Beware 5: id -a might not contain the groups= part.
98cfb1fc 42#
43# That is, we might meet the following:
44#
f62c0cf2 45# foo bar zot # accept
46# foo 22 42 bar zot # accept
47# 1 22 42 2 3 # reject
48# groups=(42),foo(1),bar(2),zot me(3) # parse
49# groups=22,42,1(foo),2(bar),3(zot me) # parse
98cfb1fc 50#
51# and the groups= might be after, before, or between uid=... and gid=...
