After _every_ iteration, 'changed' is always 'false'. We don't need to
have it outside of the loop.
See:
$ grepc update_gshadow_file . \
| grep -e changed -e goto -e continue -e break -e free_ngrp -e '{' -e '}' \
| pcre2grep -v -M '{\n\t*}';
{
bool changed;
changed = false;
while ((sgrp = sgr_next ()) != NULL) {
if (!was_member && !was_admin && !is_member) {
continue;
}
if (was_admin && lflg) {
changed = true;
}
if (was_member) {
if ((!Gflg) || is_member) {
if (lflg) {
changed = true;
}
} else {
changed = true;
}
} else if (is_member) {
changed = true;
}
if (!changed)
goto free_nsgrp;
changed = false;
}
}
This was already true in the commit that introduced the code:
$ git show 45c6603cc:src/usermod.c \
| grepc update_gshadow \
| grep -e changed -e goto -e break -e continue -e '\<if\>' -e '{' -e '}' \
| pcre2grep -v -M '{\n\t*}';
{
int changed;
changed = 0;
while ((sgrp = sgr_next())) {
* See if the user was a member of this group
* See if the user was an administrator of this group
* See if the user specified this group as one of their
if (!was_member && !was_admin && !is_member)
continue;
if (was_admin && lflg) {
changed = 1;
}
if (was_member && (!Gflg || is_member)) {
if (lflg) {
changed = 1;
}
} else if (was_member && Gflg && !is_member) {
changed = 1;
} else if (!was_member && Gflg && is_member) {
changed = 1;
}
if (!changed)
continue;
changed = 0;
}
}

shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
