bash - 打印与用户名关联的名称和主目录路径

Question

我需要询问用户名并打印与该用户名关联的名称和主目录路径

echo Please enter your username
read username

我不确定如何使用 $username 来查找有关其主目录和名称的信息。

Answer 1

awk -F: -v v="$username" '{if ($1==v) print $6}' /etc/passwd

没有awk：

cat /etc/passwd | grep "$username" | cut -d ":" -f6

用户名：

cat /etc/passwd | grep "$username" | cut -d ":" -f5

Answer 2

echo Please enter a username
read username

cat /etc/passwd | grep "$username" | cut -d ":" -f6
cat /etc/passwd | grep "$username" | cut -d ":" -f5

Answer 3

采用getent

read -p "username: " username
IFS=: read username password uid gid gecos homedir shell < <(getent passwd "$username")
echo "fullname=${gecos%%,*}"
echo "homedir=$homedir"
