awk -F':' '{ print $1}' /etc/passwd | while read -r line; do id "$line"; done
或者把下面的代码存为一个文件 ,再 /bin/bash 此文件
awk -F":" 'NR==FNR {
m[$1] = "";
next;
}
{
for (i in m) {
if ($4 ~ i || $1 == i) {
m[i] = m[i] $1 " ";
}
}
}
END {
for (i in m) {
print i ":", m[i];
}
}' /etc/shadow /etc/group

1 | A possible solution is for example with awk -F":" 'NR==FNR {
if ($2 !~ /\!/ && $2 !~ /\*/) {
m[$1] = "";
}
next;
}
{
for (i in m) {
if ($4 ~ i || $1 == i) {
m[i] = m[i] $1 " ";
}
}
}
END {
for (i in m) {
print i ":", m[i];
}
}' /etc/shadow /etc/groupYou can remove |
