How to pass multiple arguments to multiple Flags using Bash Script on Oracle Linux 9.2

To Pass Multiple Arguments To Multiple Flags Using Bash Script On Oracle Linux 9.2

Introduction:

In Bash scripting, flags are used to specify options for a script. Arguments are the values that are provided to those flags. When passing multiple arguments to a flag, you can either use a space-separated list of arguments or an array.

Procedure:

Step 1: Check the OS version by using the below command.

[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="9.2"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="9.2"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Oracle Linux Server 9.2"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:9:2:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 9"
ORACLE_BUGZILLA_PRODUCT_VERSION=9.2
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=9.2

Step 2: Create a script file named multiple by using vim text editor.

[root@linuxhelp ~]# vim multiple
Insert the following Line 
# !/bin/bash
case $1 in
     --number|-n)
         shift
         echo "You entered number as: $1"
         shift
         ;;
     --collect|-c)
         shift
         echo "You entered collect as: $1"
         ;;
     --timeout|-t)
        shift
        echo "You entered timeout as: $1"
         ;;
     *)
        show_usage
        ;;
esac
~

Step 3: Now give the executable permission to the script file by using the below command.

[root@linuxhelp ~]# chmod +x multiple

Step 4: Again long list the files to check the permission of the script file which has given below

[root@linuxhelp ~]# ll
total 8
total 8
-rw-------. 1 root root 1067 Nov 13 07:39 anaconda-ks.cfg
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Desktop
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Documents
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Downloads
-rwxr-xr-x. 1 root root  347 Nov 30 02:36 multiple
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Music
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Pictures
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Public
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Templates
drwxr-xr-x. 2 root root    6 Nov 13 07:49 Videos

Step 5: Again run the script with the flags which is mentioned in the script file by using the below command.

[root@linuxhelp ~]# ./multiple -n 5
You entered number as: 5

Step 6: Again run the script with the flags which is mentioned in the script file by using the below command.

[root@linuxhelp ~]# ./multiple -t 63
You entered timeout as: 63

Step 7: Again run the script with the flags which is mentioned in the script file by using the below command.

[root@linuxhelp ~]# ./multiple -c 6
You entered collect as: 6
