I always wonder how to assign multiple variables in for loop. Suppose I want to change the IP address of some users listed. [root@server4 ~]# cat test1 user1 user2 user3 user4 user5 [root@server4 ~]# cat test2 190.10.20.1 20.1.1.2 30.12.13.13 13.23.23.12 32.12.12.1 test1 are my users and test2 contains IP address that I want to assign [root@server4 ~]# xargs < test1 user1 user2 user3 user4 user5 [root@server4 ~]# xargs < test2 190.10.20.1 20.1.1.2 30.12.13.13 13.23.23.12 32.12.12.1 Now I am going define array [root@server4 ~]# a=(user1 user2 user3 user4 user5) [root@server4 ~]# b=(190.10.20.1 20.1.1.2 30.12.13.13 13.23.23.12 32.12.12.1) [root@server4 ~]# c=${#a[@]}  #length of array Lets see if it works [root@server4 ~]# for ((i=0;i<c;i++));do echo "${a[i]} ${b[i]}"; done user1 190.10.20.1 user2 20.1.1.2 user3 30.12.13.13 user4 13.23.23.12 user5 32.12.12.1 what if we implement
