15 | # We have to find a command that prints all (effective |
16 | # and real) group names (not ids). The known commands are: | |
17 | # groups | |
18 | # id -Gn | |
19 | # id -a | |
20 | # Beware 1: some systems do just 'id -G' even when 'id -Gn' is used. | |
98cfb1fc JH |
21 | # Beware 2: id -Gn or id -a format might be id(name) or name(id). |
22 | # Beware 3: the groups= might be anywhere in the id output. | |
f62c0cf2 | 23 | # Beware 4: groups can have spaces ('id -a' being the only defense against this) |
702a0e5a | 24 | # Beware 5: id -a might not contain the groups= part. |
98cfb1fc JH |
25 | # |
26 | # That is, we might meet the following: | |
27 | # | |
f62c0cf2 GS |
28 | # foo bar zot # accept |
29 | # foo 22 42 bar zot # accept | |
30 | # 1 22 42 2 3 # reject | |
31 | # groups=(42),foo(1),bar(2),zot me(3) # parse | |
32 | # groups=22,42,1(foo),2(bar),3(zot me) # parse | |
98cfb1fc JH |
33 | # |
34 | # and the groups= might be after, before, or between uid=... and gid=... | |
